Yes, I followed his diagram and it works.
I have however, stumbled by trying the 'setserial' command with the
idea of operating the printer with a 19200 baud serial connection.
Now, the printer just blinks at me after advancing a sheet of paper.
I'm confused over the baud_base and divisor parameters. If I want to
have the printer communicate at 19200 baud, then shouldn't baud_base
be 19200? Should divisor be 16, the default value?
Thanks

Ok, I see, its bad that there not are any tag inside the CPU design that tells

Does anyone know hot to get the Eiger Labs EPX SS-1000 SCSI card to work under
Linux? (Red Hat OR SuSE).
It would be preferable to get it to work under the installation process, since
my CD-ROM is SCSI, but I can also use my Ethernet card for install purposes.

I've been trying to setup the Xpert@play AGP card with RH-5.1 and haven't
been able to get the MAch64 Server to run. All that works is the VGA driver.
Did you do anything special with the installation? Could you forward me

The SVGA do support higher resolutions
try starting X by typing startx -- -bpp 16
startx -- -bpp 24
That tells the server to run in 16 bits per piel/24 bits per pixel
If not...Dont use a config program Try editing the XF86Config file by
hand
Read up on the configfile in the man pages.

Subject: 386 revival - problems
Date: 17 Jan 1999 14:48:23 GMT
Hi folks,
today, I decided to revive my girlfriend's old 386 which was out of use for
quite a while...
The system has an AMD386DX40, a Cyrix "Fast Math" 387 clone, AMI BIOS,
32K cache and currently 8MB memory (will be 20MB soon). I intend to have
it running as workstation[0] / X terminal connected to my own PC.
So I went and replaced it's cute li'l 40MB IDE drive[1] with a 540MB EIDE I
had lying around and installed a CD-ROM provisionally, so I could install
RedHat 5.2. Unfortunately, I ran into several problems:
- first, the install bailed out with a crc error. Obviously, I was
suspicious of the RAM chips, but after a few experiments, I discovered
that the install would proceed, if I switched the "Timing Parameter
Selection" in the advanced section of the CMOS setup from "Extended" to
"Normal". The built-in help describes this as "DMA timing, ROM timing(?!)
and AT bus cycles(?)", with "Extended" being "worst case" and "Normal"
being "best case". Extended is default.
- later, I discovered that this very option switches back to "Extended"
whenever I reboot the machine. I suspected the CMOS battery, especially,
as this PC was off for a very long time (I had to re-program the CMOS
when I first switched it on) - but that parameter is the only "volatile"
one (well - and the clock is very slow...), all others are fine.
- after I managed to finish the install, the machine booted fine (even
with that "Extended" setting). Strangely, Linux only recognises 6MB
instead of all 8MB (according to cat /proc/meminfo and top) - never seen
something like that happening before.
- the second odd thing is that fdisk complains about not having the
geometry information for the hard drives. I discovered this when I added
another 120MB IDE drive as hdb. Both drives are set properly in CMOS, but
fdisk comes up with 0 0 0 for cylinders, headers and sectors. Very odd...
Now, if anybody out there has any ideas as to what is going on with this
machine, I'd be very grateful to hear them, as I'd really like to get that
PC going again - if possible. I'd be happy to supply more information if
necessary.
Thanks in advance,
Thomas
[0] for sufficiently low values of "work"...
[1] monster drive - twice the height of the 540MB drive... :-) ...and twice
as loud...

You need to get the pcmcia distribution from somewhere around:
http://hyper.standford/pub/pcmcia
If you're running RedHat, you install as the instructions instruct.
Then you move the pcmcia config in /etc/rc.d/rc3/
from whatever it is to S09pcmcia.
(just make sure its before networking)
There you go.

Well, first, as far as I know /proc is a virtual filesystem, and doesn't
actually use hard-drive space. Don't allocate a partition for that.
Subject to suggestions by others, I would suggest giving yourself -much-
more in /home. Unless you are planning on doing your ordinary business
as root (not recommended), stuff that you download (pic's, music,
movies, etc) will likely go into your own user directory. Programs
(tar.gz's, rpms), of course, can go into /usr, but you might want to
give yourself, as user, a little more leeway.
Also, if you're planning on using your system as a personal workstation,
it is unlikely that /var will need anywhere close to that amount. /var
usually gets filled with news spools, mail spools, etc., which is of
concern to a mail or news server, and not necessarily a workstation.

A comparison of the PII 400 and Celeron 400 at
http://www.tomshardware.com shows little difference in performance
between the two chips, even though the Celeron runs on a 66MHz FSB. In
some tests (see the FPU rendering tests) the Celeron was marginaly
faster, due to the On Chip cache.

Hello!
We're trying to install Linux on an old P66 server box that has a raid SCSI
controller with two chips (one per channel) saying
NCR 53cF94-2
The controller is in an EISA bus. Do any of the NCR 53xxxx drivers support
an EISA bus?
Searching for answers I found several, but nothing with this exact number
in them; which driver should I use with these chips?
I'm sorry but I don't have any docs with box that might give more info on
the adapter..
Thanks a lot!

Thanks for the reply.
The memory is a 64 Mg DIMM, and is seated properly... so I guess I
might have been sold a pup..
How do you tell it is Parity..... it has 8 chiplets on the memory board
and one small at the end... has
HY57V658020A
TC- 10S
9846P KOREA
On the chips
COULD it be the wrong speed? (The bus is at 100 MG?)
or could the chip be faulty... :-(
Ash
This is a memory problem - you are either trying to use parity
RAM -OR- the RAM is not seated all the way. If you are installing
DIMMs, press them down until they "click" into the sockets. It
might seem as though you are about to break the mobo, but you
sometimes have to *really* force them in.
