I have two friends using the BP6, one with two 466 Celerons, and the other
with two 600 celerons, but this is overclocking : this relies on luck.

[Originally a post about /proc in another group and turned into a
hardware question]
I'm using Slackware 3.9, kernel 2.0.38. At bootup I see a message
that says something like
"/proc/bus/devices/pci not found. Can't check for conflicts."
or some such. I do have a /proc/pci, however.
It's not a problem and doesn't affect anything but was wondering where
the message comes from. I went grepping through the kernel source
and a few other places such as the rc.d files but can't find anything.
I didn't think much about the message/error `til I finally got around
to using a driver for my SiS900 network card. Just experimenting with
the module, no network hooked up yet.
When the module is loaded (or compiled into a kernel) it affects the
video in some way. I ran lsdoom and the whole screen went black and keys
were dead. Power off/on time (boy do I miss reset buttons).
Later I ran Heretic and noticed the demo would constantly pause/jerk.
I then noticed an oh-so-slight slowdown when navigating around in
Midnight Commander at the console. When I unloaded the module everything
was fine.
A future post for the networking or setup newsgroups I suppose.
Anyhind, I don't know if /proc/pci is ever checked and if not what
can be changed to make it so.
Any pointers are much appreciated.
Since I already mentioned the network card here's some info from
/proc/pci in case anyone has any ideas. It's the only PCI card in
the system, the video is built-in.
Machine is IBM Aptiva 2144-S15, 75MHz (ooh, the sheer speed of it), 32MB.

Quite a nice selection, but I'd go for one of the faster versions of
the TNT graphics card, possibly the TNT2 Ultra. This probably doesn't
offer any advantages under X, but if you want to use the 3d features
for games it's significantly faster.

BP6 allows to run two 366 Celerons (BOXed) at 550 (100 MHz) and at
600 and more with PC133 SDRAMs.

No this is not correct, on a serial channel (with a small (usually) FIFO),
there are many interrupts per second.
If for example the HD, or an other IDE device has a higher priority servicing
the interrupt, you may (and will) loose data.
In linux ifconfig (do it every now and then while downloading) will show
your packet loss, now this might just come as a shock if it is not zero.
packet loss on a http connection may cause the connection to break.
I have been (and am) experimenting with this stuff, also set
hdpar -u 1 (unmask ) interrupts for all IDE devices, to improve things.
remember only 0 (zero) packet loss even over a million packets is good.
Of cause I have had download speeds of 12.5 kB per second on com 2 with etech bullet
V90 external, but this includes compression, and was on vrml files.
Linux 2.0.30
Now with the newer kernel and glibc 2.1 on Redhat, the ppp is a BSD ???
not such good results.
Oh, sorry and the 12.5 kB / second was on a 486 DX 2 66 ;-)
Now windows on the k6-2 450 is not so bad either, but I have not found out
how to optimize things yet...
I have published 'how I did it' in the past on the modem groups form demon.uk.
For those who are into it, the doc that come with irqtune (faq) is very good too.

IIRC, you have to change the order in which the cards are detected, which
consists of:
1) Changing the order the drivers are listed in the source, specifically:
/usr/src/linux/drivers/scsi/hosts.c
and (maybe, although I don't *think* it matters)
/usr/src/linux/drivers/scsi/Makefile
such that each mention of AIC7XXX comes before each mention of AHA152X.
2) Recompiling, reinstalling, etc, etc.
That *should* do it. I will note that you can have the SCSI drivers loaded
as modules at bootup. It just requires you creating an initial ramdisk.
Good luck.

Having big trouble with my server here. Anyone have any
advice?
This unit was working perfectly fine. I powered it
off, transported it to the office, and powered it back on.
I was very careful and the machine did not get dropped,
shaken, bumped, or severely jarred in any way.
Don't even know what the "bad magic" error means...
sdc, sdd, sde, sdf drives are all in one external chassis,
while sdg and sdh are in individual external chassis. sda
and sdb are internal.
(Running rh6.1 on a sparc u2)

The superblock could not be read or does not describe a correct ext2

is corrupt, and you might try running e2fsck with an alternate superblock:
