Unable to install on CompaQ D310
Hi all I tied to install 6.1 on a CompaQ D310. At the beginning I only got a BTX Halt. Then after googling around I found a similar problem on the D510 and disabled DMA in the BIOS. Now the system boots (the same with the floppy set), but when it comes to partitioning I got No disk drives found!. The ATA controller is found in the dmesg log and the CD is obviously working. The machine is a 2.4 P4 with 768Mb and 60Gb ata disk. Any ideas? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Any suggestion regarding /DEV wipe out on freebsd 4.7?
Hello, A few days ago I was not able to log into my machine using SSH. I got this following message Server refused to allocate pty. I was, somewhat fortunately, able to log using SCP. So SCP works. The file system looked good for the most part; until I checked out /DEV. Almost everything was GONE! Including MAKEDEV. Not sure what to do. Possible clue: Before this happened, last time I was actually logged in via SSH, I ran a dropdb command on one of my postgres databases and got an error message saying I did not have permission to /DEV/NULL. Not sure what to do, I set permissions to allow write on NULL. I have done dropdb many times before and had never seen that message. If anyone has any clue as do how I may restore /DEV; or how this could have happened. I would appreciate your input. I am running freeBSD 4.7 with 2GB of memory on an Intel Xeon machine. Only thing left in /DEV is a file for each harddrive partition.

Excuse for my English.
Pair ideas for promotion FreeBSD!
1)
Everyone search for a place in the organization desktop on base
FreeBSD
Probably, it is necessary to use as follows
On one computer to force to work at once some monitors, some keyboards
and mouses.
To whom it is necessary to those can work in a word-processor to you
OpenOffice, who on the Internet please Firefox, etc. if needs to get
access up to MS products (for example Navision) that please rDesktop.
It is possible to save on licenses and on hardware!
2)
The distributed{allocated} calculations to make the standard decision
I.e. all network as one computer! This a chesspiece! MS before will
not reach never. I.e. if not capacity that suffices buy one more
machine both put anywhere and you will receive result.
3)
Then so the idea to not compete with MS and to be in its{her} current
i.e.
To not try to replace MS Server, and to do{make} back Domen. To
do{make} Net Share.
4)
Then one more problem will be never solved windows by systems. It not
effective utilization HDD, i.e. a minimum now hdd on 40Gb, Windows c
the maximum borrows{occupies} with programs 10Gb, i.e. 30 stands idle!
And if at me the park of 50 machines that is received 30х50 = 1500Gb
decent space, naturally effective from them will be likely 500Gb but
too it is not bad! To use it it is possible for additional backups and
personal needs where it is not required to raised{increased}
reliability. Though it is possible to organize network RAID.

Mirroring: gvinum or gmirror?
I'm setting up a remote server with two identical hard drives, running FreeBSD-6.1. I want to set the drives up as a mirror for data redundancy. I also want to be able to break the mirror when I need to update the OS or installed software, so that if anything goes wrong with the update on one drive I can boot back to the other one, or if all is well, re-establish the mirror and synchronise to the updated system. I have serial console access including BIOS console redirection. Based on web and Usenet/mailing list searches, gmirror looks more straightforward for this simple case, gvinum more flexible but poorly documented, and the most recent comments I can find (still all 6+ months ago) seem to suggest that gvinum hasn't completely stabilised for production yet. Is this a fair assessment? Are there any factors I've missed? Which solution is likely to suit the situation better?

If your not doing SMP then recompiling the kernel for single processor mode will make things run a little quicker because the SMP code won't come into play. with HT disabling in FreeBSD is more for the security issues about a potential exploit whereby one process in one pipe can access the priveledged information of a process in another pipe because the two cores share one processor cache and thus one cache table. To my knowledge this hasn't been exploited yet. If you just install the generic kernel you it should be only the uniprocessor one. I would just do a: cd /usr/src make buildworld make KERNCONF=GENERIC buildkernel make KERNCONF=GENERIC installkernel as opposed to a binary version assuming you haven't updated yet you won't have to install world but I believe it must have the build in the source tree to build a kernel. On your P4 though the difference between SMP and uniproc may not be worth the trouble because I don't think much of a gain would be made. on a P1 a much different story... if you aren't concerned with bad users or hackers hitting the box I would just enable HT with the sysctl variable. This will not make things run slower at all, just (in theory) less secure, which is why the veriable was created in the first place as I recall. If you are concerned I would wait until you update your system and then just build a GENERIC/CUSTOM kernel without the SMP option set. -brian I will disable smp from bios. If I have a smp kernel, I suppose there will be no problem after all. Would that be ok? The problem with having SMP enabled is that the smp kernel only detects one cpu and the system monitor only features one cpu as well as gkrellm (in Linux it shows two cpus). When compiling the system monitor shows the cpu at a maximum of 50%, so what's going on with the other 50%? writing machdep.hlt_logical_cpus to 2 in loader.conf does not solve anything. I believe FreeBSD uses the other logical CPU to handle hardware interrupts, which can still help performance. You can check dmesg to see how it's actually handling it. -- -- Skylar Thompson ([EMAIL PROTECTED]) -- http://www.cs.earlham.edu/~skylar/ While that is one method of hamdling SMP I'm fairly certain FreeBSD does not use this model. The problem with one CPU handling interrupts and one handling processes is if your doing a 9000x9000 element matrix inversion to calculate say the wave function for uranium (yeah not right, but this be some nasty math so bear with me); then even if the math library is thread aware, one CPU will be frying eggs, and the other one will be twiddling it's thumbs waiting on interrupts to process. Most likely an ACPI_THERMALZONE... From memory on my readings of Implementation of FreeBSD 5.4 ( I think thats the title, but the Black Book written by the BSD gurus...) It was decided the SMP scheduler would handle processes and interrupts simultainiously as scheduled and modified with affinities to avoid switching which CPU cache has the running process. This might be why HT is slower because it only has one CPU cache so trying to keep things on one core doesn't improve performance at all because either core can access the cache. Since HT was not the brightest thing Intel could have done (kind of like 20-bit addressing...) and since AMD has Dual cores they need to compete with I don't think tweaking scheduler code to remove affinities on HT would be in the works. I don't even know if that would help either, just thinking out loud. But Interrupts are handled by both CPUs once the additional CPUs are launched by the boot CPU via the kernel. The scheduler is designed to keep all the pipes in the plant running with process/interuppts. -brian ___ freebsd-questions@freebsd.org mailing list

If your not doing SMP then recompiling the kernel for single processor mode will make things run a little quicker because the SMP code won't come into play. with HT disabling in FreeBSD is more for the security issues about a potential exploit whereby one process in one pipe can access the priveledged information of a process in another pipe because the two cores share one processor cache and thus one cache table. To my knowledge this hasn't been exploited yet. If you just install the generic kernel you it should be only the uniprocessor one. I would just do a: cd /usr/src make buildworld make KERNCONF=GENERIC buildkernel make KERNCONF=GENERIC installkernel as opposed to a binary version assuming you haven't updated yet you won't have to install world but I believe it must have the build in the source tree to build a kernel. On your P4 though the difference between SMP and uniproc may not be worth the trouble because I don't think much of a gain would be made. on a P1 a much different story... if you aren't concerned with bad users or hackers hitting the box I would just enable HT with the sysctl variable. This will not make things run slower at all, just (in theory) less secure, which is why the veriable was created in the first place as I recall. If you are concerned I would wait until you update your system and then just build a GENERIC/CUSTOM kernel without the SMP option set. -brian I will disable smp from bios. If I have a smp kernel, I suppose there will be no problem after all. Would that be ok? The problem with having SMP enabled is that the smp kernel only detects one cpu and the system monitor only features one cpu as well as gkrellm (in Linux it shows two cpus). When compiling the system monitor shows the cpu at a maximum of 50%, so what's going on with the other 50%? writing machdep.hlt_logical_cpus to 2 in loader.conf does not solve anything. I believe FreeBSD uses the other logical CPU to handle hardware interrupts, which can still help perormance. You can check dmesg to see how it's actually handling it. No! Kernel threads (e.g. handling interrupts) aren't that much different to normal processes. Logical CPUs on a single HTT capable CPU share most of the CPU logic, especially all the external stuff (handling interrupts). Scheduling handling of interrupts on the secondary/logical core wouldn't probably help performance at all (if that is at all possible). When FreeBSD sees logical CPUs it means HTT is either enabled in BIOS or that disabling HTT in BIOS does not hide the CPUs to FreeBSD (bug in BIOS/FreeBSD). Until you enable scheduler to schedule tasks to HTT cores (with machdep.hyperthreading_allowed=1 in loader.conf) (disabled by default due to mentioned security/performance reasons) machine won't utilize the logical HTT CPUs. Therefore total CPU utilization won't be more than 50%, because there are the (unused) logical CPUs which don't get scheduled tasks. are you sure about this??? I would have figured the scheduler wouldn't see the other core at all without this option set and so it wouldn't be used in calculating load at all. 50% on a compile is fairly normal from my experience. I don't have too much experience with HT as I always opt for true SMP so I can't speak with authority on the matter. but if top isn't showing CPU 1 or 0 next to a process then it isn't computing the load on multiple cores... Also if dmesg |grep cpu doesn't show application cpu1 (and on through all your cores)... launched then the system isn't looking at the HT core at all. -brian ___ freebsd-questions@freebsd.org mailing list

Re: shared cache -- Re: SMP detection
Core 2 Duos have the EM64T extensions. Core Duos (Yonah) are a mobile chip only, not a full line of processors like the Core 2 architecture (Merom, Conroe, Woodcrest). I suspect the Core 2 chips do not suffer from the same security implications as HT-enabled processors.

I could be wrong, but that seems backwards.
I know, that's also what I thought before I had the problem. (hence
the Tip of Day!)
It's quite easy to understand when you think about it. Let's say we
have the same disk drives as above in which ad0 is bigger then ad3.
So you install the OS on the smaller ad3 disk first. Then you setup
gmirror on the bigger disk ad0. You then dump(8) the OS from ad3 onto
the broken mirror gm0 which is made up of ad0. Next you reboot on gm0
(hence on ad0). You clear ad3 which is not used anymore and try to
`sudo gmirror insert gm0 /dev/ad3` = WRONG!
Why? Because what you're actually doing is trying to synchronise a
bigger submirror disk (ad0) onto a smaller submirror disk (ad3). Hence
gmirror(8) complains that the container is too small.
What you want to do is the oposite. Which is to first install FreeBSD
on the bigger drive, then setup a broken submirror gm0 onto the
smaller disk. Dump(8) FreeBSD onto this new gm0 mirror. Reboot on that
gm0 mirror. Then finally synchronise the small submirror onto the
bigger disk onto which you had FreeBSD installed first.
But be my guest, try it out and you'll see :)
Here's what you get once the whole thing is finished:

Netgear FA511 + Linksys BEFSR41 v.2 = 6.1-STABLE woes
Someone recently gave me a Linksys BEFSR41 v.2 10/100 four-port switch/NAT router. I had previously been using an eight-port 10baseT hub. To take advantage of the higher bandwidth now available on my LAN, I bought some NICs from eBay to upgrade the 10baseT ones to 100baseT. Unfortunately, I'm having problems with the Netgear FA511 Cardbus NIC I bought for the Dell Inspiron 8600 laptop I'm using. Sometimes, transfer speeds plummet (e.g., when doing an FTP across the LAN), and often it will have problems configuring via DHCP during boot (with dc0: watchdog timeout kernel messages appearing every so often during the process). To get it to configure via DHCP when it acts up like this, I have to eject and plug back in the card. Sometimes I have to do this several times before the NIC finally is configured via DHCP. :-( The trouble is, I don't know if the problem lies with the Netgear FA511 card or with the Linksys BEFSR41, or is a problem with the FreeBSD driver. I am running 6.1-STABLE, rebuilt very recently. When I plug in the Netgear FA511 I get the following console output: cardbus0: Resource not specified in CIS: id=14, size=400 dc0: Netgear FA511 10/100BaseTX port 0xd000-0xd0ff mem 0xf6001000-0xf60013ff irq 11 at device 0.0 on cardbus0 miibus0: MII bus on dc0 ukphy0: Generic IEEE 802.3u media interface on miibus0 ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto pcconf -vl says the following about the card: [EMAIL PROTECTED]:0:0: class=0x02 card=0x511a1385 chip=0x19851317 rev=0x11 hdr=0x00 vendor = 'ADMtek Inc' device = 'AN985 FastNIC CardBus 10/100 Fast Ethernet Adapter' class= network subclass = ethernet The strange thing is that the MAC address of the card is not probed successfully. I have an AN985-based Linksys LN100TX PCI NIC that reports much the same information (minus the cardbus0: ... line, and dc0: ADMtek AN985 10/100BaseTX ... instead of Netgear), but it also reports dc0: Ethernet address: 00:0c:41:21:... after the ukphy0 information. I get no such line with the Netgear NIC. The cardbus0: Resource not specified in CIS: id=14, size=400 does look worrying. The MAC address assigned to the card by the OS is 00:00:00:00:00:00, and this is also the MAC address reported in Windows. Surely this can't be right? The OUIs I could find assigned to Netgear are 00-09-5B, 00-0F-B5, 00-14-6C, and 00-18-4D; 00-00-00 is supposed to be Xerox. The card appears to work in Windows, but sometimes has speed problems, as in FreeBSD. Does the weird MAC address, along with the cardbus0: Resource not specified in CIS: id=14, size=400 indicate that perhaps the EEPROM is faulty/incomplete, or could it be the FreeBSD dc driver can't correctly probe the information? The Netgear FA511 is on the hardware compatibility list for 6.1 as being fully supported; I checked before I bought it. On the other hand, the reason I wonder whether the problem lies with the Linksys BEFSR41 router is that I also had problems with the 3Com 3C589C EtherLink III 10baseT Cardbus NIC I formerly used with the laptop. The 3Com NIC worked fine with FreeBSD (using the ep driver). However, it would often cause problems with the LAN when attached to the Linksys BEFSR41 when multiple 100baseT devices were active. I have two desktop systems using Intel PRO/100 PCI NICs (with the fxp driver) that would suffer speed degradation problems during bulk transfers across the LAN when the laptop was connected to it. Does the Linksys BEFSR41 v.2 get muddled with autonegotiation? (It is running 1.46.02, Aug 03 2004 firmware.) For example, I appear to have better results in Windows with the Netgear FA511 if I force the media to 100baseT full-duplex, but if I try to do this in FreeBSD then the LED on the Linksys indicating full duplex/collision does not illuminate (but the link and 100baseT ones do). Furthermore, the NIC never gets configured via DHCP; just endless occasional dc0: watchdog timeout messages. So, do I have a faulty Netgear FA511 Cardbus NIC? Is my Linksys BEFSR41 v.2 flaky? Is this just one of those deadly combinations (I don't have problems when just the two fxp devices are connected to the LAN)? Will a different Linksys firmware fix the problem (if so, which version)? I'd love to know (and quickly, as I have to return the Netgear FA511 if it is faulty).

Re: firefox starts up always in the first virtual screen in XFCE
Hi, your comment rang a bell. The Firefox window was apparently maximized when I upgraded the box. Firefox remembers the previous window size, and it seems like the (updated) XFCE window manager now thinks that the (updated) Firefox window is too big, and displays it on virtual screen 1 as a fallback strategy. I resized the window a little, closed Firefox, and opened it again - now it will open on the very screen which happens to be active. Problem solved. Poster embarrassed. Thanks a lot. regards, Markus Norberto Meijome writes: sounds like a session manager saved firefox on this desktop... not sure which one would do it when you start it up (usually they restore programs on startup...) -- Markus Hoenicka [EMAIL PROTECTED] (Spam-protected email: replace the quadrupeds with mhoenicka) http://www.mhoenicka.de ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: 6.1 kernel messages

Is it? I don't think it's a problem - at least not a major problem that you need to lose sleep over, unless you're a kernel hacker. It just means that those particular drivers have not yet been updated to support fine-grained kernel locking and so the Giant lock is acquired on the entire kernel when these drivers run - meaning that other processes can't be serviced by the kernel at the same time. In FreeBSD 4.x this kind of message didn't exist because having only one process accessing the kernel at any one time was the *only* possibility back then. Then there's this: acpi0: PTLTD RSDT on motherboard acpi0: Power Button (fixed) acpi: bad write to port 0x070 (8), val 0x43 acpi: bad read from port 0x071 (8) AFAIK this is FreeBSD telling you that your machine's BIOS is trying to access memory areas where it has no business going.

Re: Mirroring: gvinum or gmirror?
I've got a write-up of the steps required to do this if you or anyone else needs them. I also routinely disconnect one of the drives in my mirror before a major upgrade to the OS or ports so that if I mess it up, I can boot back to the previous state. I have a write-up of the steps needed to do this remotely over ssh (again, if you or anyone else needs them). Elliot I for one would like to see your writeup. As I'm starting to experiment with gmirror I think it would be helpful.

Anyone Using the New Free Mulberry Mail Client?
There used to be a port of Cyrusoft's Mulberry mail client that installed the Linux rpm version; then Cyrusoft went bankrupt and the port dissappeared. Mulberry is now available for free as a standalone Linux binary: http://www.mulberrymail.com Has anyone got this working? If you just run the binary it opens and can be be configured to read an imap mailbox, but a lot of the error and warning pop-up boxes are missing text and buttons.

If your not doing SMP then recompiling the kernel for single processor mode will make things run a little quicker because the SMP code won't come into play. with HT disabling in FreeBSD is more for the security issues about a potential exploit whereby one process in one pipe can access the priveledged information of a process in another pipe because the two cores share one processor cache and thus one cache table. To my knowledge this hasn't been exploited yet. If you just install the generic kernel you it should be only the uniprocessor one. I would just do a: cd /usr/src make buildworld make KERNCONF=GENERIC buildkernel make KERNCONF=GENERIC installkernel as opposed to a binary version assuming you haven't updated yet you won't have to install world but I believe it must have the build in the source tree to build a kernel. On your P4 though the difference between SMP and uniproc may not be worth the trouble because I don't think much of a gain would be made. on a P1 a much different story... if you aren't concerned with bad users or hackers hitting the box I would just enable HT with the sysctl variable. This will not make things run slower at all, just (in theory) less secure, which is why the veriable was created in the first place as I recall. If you are concerned I would wait until you update your system and then just build a GENERIC/CUSTOM kernel without the SMP option set. -brian I will disable smp from bios. If I have a smp kernel, I suppose there will be no problem after all. Would that be ok? The problem with having SMP enabled is that the smp kernel only detects one cpu and the system monitor only features one cpu as well as gkrellm (in Linux it shows two cpus). When compiling the system monitor shows the cpu at a maximum of 50%, so what's going on with the other 50%? writing machdep.hlt_logical_cpus to 2 in loader.conf does not solve anything. I believe FreeBSD uses the other logical CPU to handle hardware interrupts, which can still help perormance. You can check dmesg to see how it's actually handling it. No! Kernel threads (e.g. handling interrupts) aren't that much different to normal processes. Logical CPUs on a single HTT capable CPU share most of the CPU logic, especially all the external stuff (handling interrupts). Scheduling handling of interrupts on the secondary/logical core wouldn't probably help performance at all (if that is at all possible). When FreeBSD sees logical CPUs it means HTT is either enabled in BIOS or that disabling HTT in BIOS does not hide the CPUs to FreeBSD (bug in BIOS/FreeBSD). Until you enable scheduler to schedule tasks to HTT cores (with machdep.hyperthreading_allowed=1 in loader.conf) (disabled by default due to mentioned security/performance reasons) machine won't utilize the logical HTT CPUs. Therefore total CPU utilization won't be more than 50%, because there are the (unused) logical CPUs which don't get scheduled tasks. are you sure about this??? I would have figured the scheduler wouldn't see the other core at all without this option set and so it wouldn't be used in calculating load at all. 50% on a compile is fairly normal from my experience. I don't have too much experience with HT as I always opt for

VIA C3 - cant boot CD
i have an ML6000 (no floppy) and have downloaded the 4.11 mini-iso image, and burned it to a CD-RW. CPU: VIA C3 Nehemiah (666.55-MHz 686-class CPU) after rebooting, the CD is found, and a boot attempt is made. within 5 seconds, the kernel locks up after about 3 seconds of the kernel data+234238 text+23432 stuff and the /-\|/-\ twirling prompt, leaving a / as the first character on the next line. the ISO is the exact size it should be, and i could gzip -t mfsroot.gz in the /boot directory without error - so i guess it's a good image. i am running 4.10 currently, and have no boot problems off the hard drive. any ideas as to what could cause this lock-up at boot time? i thought the ISO's are made with the mkisofs --no-emul-boot, yet the CD is recognized as a 2.88 floppy, and boots 0:fd(0,a)/boot/loader. i never booted off CD's before, and don't know what i should expect exactly. thanks. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Help re nvnet driver
Hello: I have a machine with two SLI slots and two regular pci slots. The motherboard is Gigabyte with nVidia network interface built in. I have one regular pci slot taken with a video card and one with a D-Link nic. I need another nic and as it stands either the video card goes or I get a functional nvnet driver. The system has refused to deal with the nvnet interface and the compilation of the driver for it was initially unsuccessful. I posted a note to this list about it at the time and was told after some delay that the nvnet driver was 'broken'. My plan is to use one of the extended pci slots for a SCSI adapter which leaves the other extended slot unused(and unusable if I understand correctly). The machine has no built in video. Can anyone tell me if there is a functioning nvnet driver avail- able presently and if it will run on v6.0. My present use of the machine is as a development machine and I need to configure Apache for mock virtual sites with both an internal network connection and a mock external connection. Eventually, I will have the machine actually connected to a public address so for that I need the extra net work interface card also. I think I can get by with six internal addresses alias to the same card and split them up as far as Apache is concerned but having the use of the built in network interface will be a great help. Other wise every thing is satisfactory with FreeBSD on this machine. I'm building a third machine along the same lines (but it has more standard pci slots and only one extended slot which will also be for a SCSI adapter card). I'm shoe horning my budget for the project so that isn't a viable alternative for me at this time. Thanks in advance.
