A careful reading of the description of this device suggests that it
will only work on the particular motherboard shown. It does look
interesting, but I suspect Abit's BP6 board will be better. I believe
the BX chipset can only use two processors, the GX though, can use at
least 4. It seems it would be possible to design an adapter like the
one shown that would plug into slot 2 - and use 4 processors on a dual
board. It might even be possible to put additional cache and a
controller on the adapter - probably the engineering costs and low
market potential will mean this will not be tried...

Subject: 2U servers
Date: Mon, 7 Jun 1999 04:38:11 GMT
Has anyone had good experiences with "off the shelf" 2U rackmount servers
and Redhat Linux? I've been using the Compaq 1850R, but those just aren't
dense enough (3RU). I've been looking at the HP LPR, but it only supports
2 hot swap drives (making a minimal 3 drive RAID 5 array impossible). I've
also looked at the 2U server by VAResearch. It seems nice, but also doesn't
have space for 3 hot-swap drives. My minimal config is something like:
2 x PIII-450
256mb ECC SDRAM
hardware RAID controller (level 5)
3 x hotswap fast/wide/ultra 7200rpm drives (RAID5)
100BT ether
usable integrated SVGA
Occasionally, I also have to stash NT boxes at our datacenter so something
that's friendly with both Redhat 6.0 and NT4 would be ideal.
Any suggestions would be greatly appreciated. I'm hoping I don't have to
roll my own.

Hi~
Do the following. Type:
pnpdump > /etc/isapnp.conf
Edit /etc/isapnp.conf by uncommenting the two lines that refer to your
io and irq. "man isapnp.conf" for more info. Then add the following
lines to /etc/conf.modules:
alias eth0 8390
alias eth0 ne
options ne io=240 irq=3 # Enter your own values
Reboot. Type "dmesg" and look for several lines refering to eth0 and
isapnp devices being configured. Also type "ifconfig", lo and eth0
should be listed. Let me know if this helps.

Subject: DLT4000: mt-st can't fsf/bsf
Date: Mon, 07 Jun 1999 03:39:49 +0000
Hello All,
We recently obtained a pair of DLT 4000's for system backups. We are
running into problems and was wondering if anyone else had experienced
this. When we try to move the location of the tape in relation to
end-of-file markers the (mt) command immediately returns (as if
sucessfull) and the tape moves nowhere. (i.e. mt fsf 1, mt bsf 2,
etc..). The tape can rewind, and forward to end of data (mt eod).
Backups and restores work properly... but I can't move it in relation to
file markers.
Using backup and restore we've been able to write multiple files to the
disk. For example:
/sbin/dump 0f /dev/nst0 /
/sbin/dump 0f /dev/nst0 /home
...then...
mt rewind
/sbin/restore Cf /dev/nst0
...verifies /...
/sbin/restore Cf /dev/nst0
...verifies /home
* however *
mt rewind
/sbin/restore Cf /dev/nst0
...verifies /...
mt rewind;mt fsf 1
/sbin/restore Cf /dev/nst0
...verifies /...
We've been able to access multiple files by 'dd'ing out to dev null
untill we reach the file we need, but this is much less than optimal.
* Example (to interactively restore /home) *
mt rewind
dd if=/dev/nst0 >/dev/null
...wait a long time, till it reaches end of first file...
/sbin/restore if /dev/nst0
I've looked at the 'st' code in the kernel and it appears to be doing
the right thing (The documentation that came with the tape drives detail
the SCSI commands to manipulate the drive). If anyone's got further
information it would be greatly appreciated.

My somewhat hazy memories of Hamming codes suggest that 32 data bits
need 6 bits for the syndrome, since, as you point out, the error may be
in the Hamming bits. My rather clearer memories of the Cray 1A suggest
that the best way to use 9 bit memories would be 8 wide, using 72 bits
to hold 64 data bits (Cray RAM was on 1 bit wide chips though). You
then have 8 Hamming bits, which is sufficient space, in principle, to
point to any of the 72 and also detect (though not correct) 2 bit
errors. You do need a serious problem, like long running number
crunching jobs, to make this worthwhile, as the logic is a good deal
more complicated than parity on 9 bits, and takes some time, so that for
a given technology the memory runs slower.

I have been using the 7502B for a long time, but I have
had to burn with only 2x. It has always failed when
trying the 4x-mode. I use the 2.0.36-kernel and
a Adaptec 1542 ISA scsi-card.

Subject: SMP and sig 11 -- more likely? (please help!)
Date: Mon, 7 Jun 1999 04:48:44 GMT
Recently, I added a second CPU to my linux PC. Now I've got 2 166 MHz
MMX Pentiums. I'm running kernel version 2.0.34.
If I'm not using the system much, it'll go days and days and days without
any problems. But if I'm using it heavily, about once every 3-4 hours
the X server will cut out on signal 11. Running an mp3 player constantly
increases the likelihood that this will happen.
>From what I remember, this indicates a memory fault.
My question is, will upgrading the kernel to 2.2 help out? Also,
anecdotally I don't seem to remember as many incidents when I have the
case off. I have a large fan blowing in, right over the CPUs. I have two
exhaust fans at the back, one in the power supply and one more above it.
One CPU has an intel-attached fan, and the other has a peltier unit with
heat sink and fan. I can't imagine that heat is a problem, but I don't
have any kind of thermal monitoring on the motherboard (Tyan Tomcat IIID).
Any help would be appreciated.

Basicaly put "kppp" is not written for the Red Hat Dastro and will not
work without major configuration changes.
The easiest way I've found to setup pppd under RH 5.2 or RH 6.0 is:
# linuxconf { either under X or text mode take you pick}
- Networking
- Client tasks
Select PPP/SLIP/PLIP
Click the ADD button
Make sure PPP is selected
Click the Accept button
Fill in the following fields
Phone Number
Modem Port
Click the use PAP check button if using pap
{ Or try PAP even if the ISP says use CHAP
Because the may support it for there
MS-Windows users. And Not realize that pppd
under Linux can do the same thing.
}
Login Name
Password
Click the Customize button
Select Allow any user (de)activate the interface
Study the other pages
Click the Accept button
Click the quit button on the PPP/SLIP/PLIP page
Select Name server specification (DNS)
Fill in the Name Server Information asked by this page.
Click the Accept button
Click the Quit button
Press enter on the next screen to apply the updates.
Now at the command prompt
$ /sbin/ifup ppp0 will bring up the connection
$ /sbin/ifdown ppp0 will bring down the connection
Under X simplily load the program "usernet" is a simple to use one to
get you started, though there are other choices out there.
RedHat 5.2 and 6.0 versions of the Linux Dastro's are simple enough,
even a MicroS*t user should be able to set it up.
It's a whole lot simpler then MS-Widows to install and setup.
