You need to go to the 2.4 kernel to use more than 4 gig of memory.  Since it
was just released, there are probably still some teething problems....

Dell and VA Linux will be happy to sell 4 processor machines with lots of
memory, disk, etc:

        http://www.dell.com/us/en/bsd/products/model_pedge_pedge_6400.htm
        http://www.valinux.com/products/4450ts.html

Note, these come with Red Hat Linux, but you should be able to put SUSE on if
desired.  If you buy machines with Linux installed, then you don't have to make
sure whether or not the components are supported by Linux.

I do not know anything about web camera, so here is a translation:

I have some problem with my web camera in RH7.0
The camera's name is TerraTec USB (not pro).
I have compiled with CPiA in the 2.4.0 kernel.

Yes, I checked each of these when I did it before (the machine has not been
available for shutdown since I tried the first time), and the one thing I did
notice was that the BIOS only saw 19 of the 80 GB.  That is interesting . . .

I didn't think there would be a size limitation with the BIOS, i.e., the master
drive is 12 GB.  Could this have something to do with it?

200W power supply with that kind/amount of hardware ??

Many people buy 350W or 400W power supplies for their Athlon.
I figure they have a reason...

In short: Athlon is known for power problems, and if you have a TNT2, then
it's even worse.

This is really f***ed up; a CD-RW should not appear as "sda" no matter
what.  When you get back into the system, make sure that ide-scsi
support is built as a module, not directly into the kernel, and this
should not present a problem to the booting process as long as you're
not using a RAMdisk.  (RAMdisks are completely unnecessary if you
compile SCSI support, SCSI disk support, and support for your particular
brand of SCSI adapter directly into the kernel.  Their only purpose is
for installation and rescue systems; IMHO RedHat's reliance on the
RAMdisk causes more problems and confusion than it solves.)

Also go into the BIOS and disable (U)DMA for this device; CD-ROM-type
devices don't need it, most of them can't use it, and trying to use it
with a CD-ROM can cause funky errors like that to happen.

Anyway:  boot from a bootdisk (you DO have a bootdisk, right?
http://www.toms.net/rb/ if you don't, and keep 2 or 3 copies around) or
boot from a bootable CD ("linux root=/dev/sda3" or wherever your real
root partition is) then see if you can make those changes discussed in
the first paragraph.  HTH, bonne chance....

If your're running it as a router and a web server I wouldn't worry too

Keep in mind that the kind of memory you would get would be EDO or FPS
simms, which aren't being made anymore (at least not cheaply). You're
looking at $90 for 32 megs, and you have to buy them in pairs on that
system. I don't think Microcenter carries 16 meg EDO any more. Try
getting them used, maybe (?).

I had a problem getting an 8 gig drive to be seen by a P200, so 6
sounds about right, maybe even 4.
Most drives are 3 1/2 inch wide. Check to see if the 1660 has any funky
rails, which I doubt (you could reuse them anyway). You can get a 5 1/4
inch Quantum Bigfoot, but I've seen too many of them fail.

For Linux I like 3com cards, but they can be a hassle in a router when
you have two of them. I've used Lynksys cards too, (a 3com and a
Linksys together in a router, with Red Hat) and they do fine.

Subject: Athlon motherboard suggestions (with RH 7.0)
Date: Fri, 26 Jan 2001 02:39:34 GMT

Hi all,

I am going to upgrade my computer with a new CPU, motherboard, and HD.

I want the fastest CPU around (within reason), and so a 1.2Ghz Athlon
seems to be a good choice for the price. So, which motherboard
do you recommend for this CPU? I will mostly be running a desktop machine
at this point, but I want a fast one (I don't like to wait for g++ to
finish!)

Also, what HD is good? I had thought that SCSI was what I wanted, but now
I am thinking ATA 100 will be fine. I kinda like the IBM drives simply
because they seem quiet! I'm under the impression that RH7.0 does
not like the promise controller, but so long as it works without a fuss on
a simple install of the OS, I'll be happy to wait till it is supported (in
RH7.1?)
or I get the energy to play with newer drivers my self.

My main goal is a highly capable machine, perhaps initially with lower
performance due to RH7.0 not supporting it fully, but with the knowledge
that
in about 3 months(?) RH7.1 will support it.

I know that these are vague-ish requirements, so just a gut feeling,
your own experiences, etc, will be fine to get me started

Thanks!
Anthony

Subject: How I Got My ATAPI Tape Drive To Work
Date: Fri, 26 Jan 2001 03:21:45 GMT

Lots of people (myself included) have had problems configuring their
ATAPI tape drives to work on GNU/Linux systems.  I finally got mine
working and hoping to spare others' nerves, I'll reveal how.

I configured it to use SCSI emulation.  I also compiled relevant support
into the kernel rather than as modules.  Here are the configure
parameters (I use make xconfig):

        Under "Block devices"
                
                "n" to "Include IDE/ATAPI TAPE support
                "n" to "Include IDE/ATAPI CDROM support"
                "y" to "SCSI emulation support"

        Under "SCSI support"

                "y" to "SCSI tape support"
                "y" to "SCSI CD-ROM support"    
                "y" to "SCSI generic support"

"y" means to compile the support in question into the kernel rather than
to load it as a module.  I left everything else as-is.  I tried modules
for these items but got unresolved references when one or two were
loaded.  If you don't know how to relink and install the kernel, read:

        /usr/src/linux/README

I also added to lilo.conf append commands:

        hdc=ide-scsi hdd=ide-scsi

where hdc and hdd are my tape drive and cdrom drive.

The tape drive are /dev/st0 and the cdrom /dev/scd0, so I made these
links:

        ln -s /dev/st0 /dev/tape
        ln -s /dev/scd0 /dev/cdrom

since mt(1) can use the TAPE environment variable, I set it:

        export TAPE=/dev/st0

On some installations, mt(1) uses a default of /dev/tape I believe, so
you might not need to set TAPE.
                
That's it!  Everything works. I have:

Distro: Mandrake 7.2
kernel: 2.2.17-21mdk
MB: PCChips M805LR
CPU: 1 GHz K7
RAM: 256 MB
Tape: HP Colorado 8 GB ATAPI
CD-ROM: cheap 56X ATAPI
        
Good luck!
