Hello,
Many thanks for the tip. I do have a winmodem as I mentioned.
The site you recommended did say that if you have a WINMODEM it will not work.
So I guess I am back to where I started. Can anyone help?

My cdrom worked perfectly with lm6 but after installing lm7 when I try to

Can anyone help me? I tried supermount on the install but it didn't work so
I reinstalled without it.

Well, up to 133M/s - that's the most the PCI bus can handle. But that's
fine, because no drive can sustain speeds even close to that.

Subject: can't play audio CD's but works otherwise
Date: Mon, 26 Jun 2000 14:05:55 GMT
Greetings:
I'm having some dificulties playing audio CDs from my new
cdrom. My system is a redhat 6.2 with kernel 2.2.16. Basically I can
mount and read CDroms but I can't seem to be able to play CDs.
I recently upgraded my 4x scsi2 cdrom with a much faster one,
NEC DC-3010. The system boots up just fine, I can mount the cdrom and
read iso fs, no problems. But when I try to play my CDs with various
CD player software, I only hear a half second of sound and then
nothing. The track slider on XMMS is jumping back an forth in place as
if the cdrom is skipping. I did not have any such issues with the
older cdrom. Ditto for kernel 2.2.14, same problem. All the CD players
can read the number of tracks and correctly lookup the CD in CDDB.
They're both scsi and have the same 50 pin connector. The only
difference I can tell is that the new cdrom is ultra-scsi, but my card
supports it and I can mount and read from CDs.
If anyone has any insights as to what's up with this, please
let me know.
really wierd.

I like Tyan motherboards. They're not usually the top performers, but
they are solid and stable. Which, IMO, is more important. I'm not
familiar with this specific board, however.
You may also want to consider a board with built-in Ethernet and SCSI.
Compare the difference in price with the $205 you're planning on
spending for the SCSI card and network card. A board with dual-channel
Ultra2 SCSI may be less expensive than your existing board plus the SCSI
board.
> ATX 6 drive bay case with 250W power supply 30
For what you're doing (dual processors, two hard drives, lots of RAM),
I'd go for a full-tower case (9-10 drive bays), and at least 300W for
the power supply.
Also, add some extra fans - most cases only have the one fan in the
power supply. An extra one at the back of the case (below the power
supply) and at the front (near the bottom) will greatly improve
airflow. With a configuration you're describing, the system will
generate plenty of heat - you'll want to draw that heat away as quickly
as possible. (When installing the extra fans, be sure to pay attention
to how the air is flowing - if you install a fan facing the wrong way,
it will impede airflow and cause overheating.)
> PS2 keyboard with tactile response 30
> PS2 3 button mouse 10
OK. Keyboards and mice are personal things. If you know what you want,
go for it. If you're not sure, go to a store with them on display and
try them out. Some feel better than others.
> 2 each 256MB 72 bit PC/100 SDRAM 600
512M RAM is probably overkill, but I don't know what you want to do with
the box. If you're running a high-RAM application (like a database
server, or compiling lare amounts of code, or photo-editing, etc.),
you'll need it. If you just plan on web surfing and playing MP3 files,
this is much more than you need.
> 2 each 600mhz P3 processors (slot 1 type SECC2) 440
Very nice. Be sure to keep them cool. Apply thermal grease between the
CPU and the heat-sink. Unless you absolutely know that your system's
airflow is sufficient to cool the chips, be sure to use a heat-sink with
a fan in it. Passive heat sinks only work well if your case fans can
move enough cool air across them.

> Adaptec 2940UW SCSI card 175
Get SCSI hard drives and a SCSI CD-RW drive. They'll cost a little
more, but the extra performance is well worth it. (If you don't want
SCSI drives, then ditch the SCSI card.)
Note that mother motherboards only include two IDE channels. And only
one drive on each channel can be in-use at any given time. Since you
are planning on three drives, one of the channels will have two drives
on it. This will hurt performance for any application that accesses
those two drives at once.
for the SCSI card, don't use Ultra-Wide. Spend a little more and get an
Ultra2 controller. The extra speed (80M/s vs 40M/s) will come in handy
since you're attaching two hard drives - and may be accessing them both
at once. Furthermore, Ultra2 (LVD) drives allow for much longer cables
(up to 12m) than Ultra-Wide (which only allows 1.5m). The longer cables
will allow you to use more drives.
When you get the CD-RW, look for one that is also LVD (Ultra2 or Ultra3)
SCSI. If you mix LVD and non-LVD drives on a single bus, the bus will
run in non-LVD mode and you'll be stuck the the slower speeds and
shorter cables of Ultra-Wide SCSI.
Alternatively, two SCSI channels (either two cards or a single
dual-channel card) will help solve this problem. Put your LVD drives
(like hard drives) on one channel, and your non-LVD drives on the
other.
> 2X AGP graphics card (S3 chipset with 8MB) 300
What S3 board? S3 makes a lot of chipsets. I think you're estimating
too much money here. $300 can get you a board that is a lot nicer than
an older S3 chipset and a 8M. Check out some of the boards based on the
ATI Mach-64 and Mach-128 chipsets. Also the nVidia Riva-TNT2, and the
Matrox GeForce chipsets are nice.
Visit http://www.xfree86.org/ and browse around there to learn what
chipsets are compatible with X on Linux. Be sure you install the latest
version of XFree86 (3.3.6 or 4.0). Most current Linux distributions
should be including 3.3.6 by now.
> 20 inch Vision Master 1600x1200 monitor 1000
I don't know the specs here. In general, aperature-grill tubes look
sharper and brighter than shadow-mask tubes. Smaller dot-pitch looks
better. Higher refresh rates at your preferred resolution will flicker
less.
> 100mb PCI network card 30
Just make sure it's Linux compatible. Check the list of drivers that
comes with your distribution if you're not sure.
You didn't mention a tape drive. Look for a SCSI drive. You are going
to want to make backups of your two 18G hard drives. (Unless you have
another computer with a tape drive somewhere on your network that you
can use for your backups.

The parts should be compatible.
For pricing, you will find that prices can vary widely. If you're not
picky about who you order from, check out PriceWatch
(http://www.pricewatch.com). They list items from many dealers so you
can comparison shop.
Local dealers can either give your great buys, or they can rip you off.
If you know what you're buying, you can do well with them. Computer
flea markets ("shows") are also good sources - you usually find a lot of
local vendors in one place at these kinds of events.

Subject: 10Gb HD - can't mount vfat filesystem
Date: Mon, 26 Jun 2000 22:17:12 +0800
Hi there,
I can't mount a FAT32 partition from my second hard drive in Linux.
The command I am using is mount -t vfat /dev/hdc6 /mnt/d. The error
message is as follows:
"Wrong fs, bad home block, incorrect mount option or too many mounts."
The first drive, a single partition with Win95, mounts OK as /dev/hda1
with type vfat.
On the second drive I can access the Fat32 partition in Win95 OK as drive D:
and it appears to
be reporting the size correctly.
I am dual booting Red Hat Linux 6.2 and Windows 95 through LILO with the
following
disk layout:
. Windows 95 system & data on Quantum BigFoot CY4320A 4.2Gb IDE drive.
. Linux partitions occupying 1st 2.58 Gb of a Samsung SV1022D 10Gb IDE
drive.
. Extra FAT32 partition occupying remaining 7Gb or so of above disk.
I have tried setting partition ID to 0x0b and to 0x0c (LBA) but neither
configuration works. Is there some other configuration in fdisk or
mount option that I should try?
The BIOS reports the primary and secondary disk parameters as:
4335 527 255 0 8959 63 LBA

I live in Montgomery County and have been unsuccessful in getting it to
work. I got one hint from the LDP
(http://www.redhat.com/mirrors/LDP/HOWTO/Cable-Modem/index.html) but,
that didn’t work. I followed all the instructions about PAP, adding
routes (except when I execute route add –net 10.0.0.0 I get a SICOATTR
error), etc. I have logged all I can and the most I can figure is that
after my username and password is entered (and pppd reports and serial
connection established) Ex-pressnet comes with “Backup Authentication”
at which point pppd reports “alarm” and sends two “^M” and a modem hang
up occurs. I know this has to do with PAP however, I don’t know how Ex-
pressnet expects the PAP stuff or if a second Authentication is
occurring because after “Backup authentication” Ex-pressnet gives that
gibberish (~&^$%&) that you get just before making a proper PPP
connection, except it just hangs up. Please, is there any help you can
offer me?
I am running RedHat 6.1 on a Pentium 100mhz with a Tulip based Ethernet
card, and a ZOOM ISA PNP modem (fully functional on non cable modem PPP
connections). Hey I just want my cable modem up so I can use my linux
box as a firewall like I did when I used Earthlink. Having a win98
machine be my front gate just makes me uncomfortable.
Thanks in advance for any help you can give me.

Subject: Laptop modem not found!!
Date: Mon, 26 Jun 2000 10:14:37 -0500
Hi,
Programs like rp3 and kppp are unable to locate my pcmcia modem card. I
get messages like
`Sorry, modem not responding', even though the modem is physically
there. This is w/RH6.1.
It did work with a previous version -- RH5.1. Any laptop users seen
this before? My pcmcia
ether card is configured correctly however.
My own guess as to reason to this problem is IRQ conflict. Typically the
BIOS setting for
ttyS0 is 4. However since that is the same IRQ for ttyS1, the OS resets
it at boot time to another
available one -- in my case-- to IRQ 11. The `setserial' command gives
me the new IRQ, not
the original BIOS setting. There is no way to check which IRQ programs
like rp3 and kppp are
seeing, so I am not sure if this conflict is what is getting in the way
of finding the modem.
Any suggestions towards thie original problem or towards the IRQ
conflict which may or may
not be causing this problem is appreciated.
Thanks

There have been a few reports of external LoseModems, but those are few
and far between. If the box/manual says that the thing works with DOS,
it'll work with Linux. The modem init string is usually "ATZ" to start
(reset modem to default factory parameters) and if you don't get good
performance, you can tweak it using the modem manual as a reference. kppp
or GNOME's ppp-dialer are relatively decent at setting up modems; try
those if you have them and post again if you have problems....

Cobalt kit is good if you don't want to configure your own OS and have
flexability to modify it and add new hardware and and use off the shelf
parts if it goes BANG!
But they are overpriced and proprietary, and also very nasty to the small

Yes, although a better way is to propogate root's identity.pub to
