You don't say what DIMM modules you have...
Best thing to do? Get two -matched- modules, high-quality, name-brand
stuff, 7 or 8ns, matched right down to the lot number, same manufacturer,
same dram chips on each if possible...
Generic, God-only-knows-who-made-it computer-show special RAM is probably
the worst choice for a Supermicro.....
It is not a motherboard problem, but SM implements SPD the way it was
-intended- to be implemented. This is why I have always said that the SM
boards are "finicky" with some brands of pc100, specifically it does not
like mixed-brands if you are using more than one module. On the other
hand, it is also another way that these boards achieve the stability they
are well-known for, because mixed-brands, mismatched modules, etc, cause
problems.. RAM that will run fine in an Abit, Asus or Tyan maybe will or
maybe will not run well in the SM board.
If the above does not apply to you, in that you already have good quality,
matched modules, then I would start looking at the scsi chain, at the
termination scheme, and check to see that your drives are NOT jumpered to
power the bus, because Adaptec controllers like to do this, and they do
not like it when the drive(s) power the bus.

Keep in mind the 1024 cylinder boot limit (which corresponds roughly to
8 GB).

I don't know anything about Compaq laptops, but Debian 2.1 installed just
fine on my old Toshiba with 3.9Mb of useable RAM. The installation isn't
quite as automated, however-- you have to boot a low-memory boot disk and
create a swap partition just to load the installation package....

I think I had that problem when I switched to 6.1 from 6.0.
Try using /dev/scd0 and /dev/scd1 instead of /dev/sr0
and /dev/sr1

I suppose one could look them all up and add them up, but an ammeter
seems to make more sense. The biggest problem with that is the voltage
drop across the ammeter, which could be a fair fraction of a volt in
some cases. And cutting into the circuit to do the measurement is a
genuine PITA, very difficult to get decent, low ohms connections. If
the PSU has a current foldback/limiter circuit, you might be able to
measure across that and do the math, but please be aware there are
potentially lethal voltages inside that PSU box.
Cheers, Gene

Subject: what printer type for IBM4019 - netscape | gs | lpr
Date: Wed, 01 Mar 2000 02:02:10 -0500
Hello,
I am using an IBM 4019 LaserPrinter on RedHat 6.1. I set up the lpr
print queue using the HP LaserJet printer type. It works for now,
printing text files to it. However, I am trying to set up netscape to
print it's postscript output thru the gs command, to this printer.
I am testing with a postscript file on the disk named index.ps. The
command I use to print this postscript file is:
gs -dNOPAUSE -sDEVICE=laserjet -sOutputFile-\|lpr -qBATCH index.ps
This prints a lot of junk. The problem is that the IBM 4019 does
not print the laserjet PCL file it gets from the gs command very well.
Does anyone know the correct printer type to use in initialy setting
up the lpr print queue with an IBM 4019. And also, what is the correct
output device to use in the gs command. Laserjet does not seem to do
the trick.
Thanks,
Greg Nedel

I am putting together a server primarily to run squid as a proxy cache.
Given that the performance of the disk subsystem is very important for this
appication I have been looking at the adaptec 39160 interface together with
some 10,000rpm disks.
My question : Does linux support the 39160 (or 29160 come to that. If not
does anyone have any recommendations.
Also if anyone has any tips on selection of hard disk vendor for this type
of disk.. IBM, Quantum and Seagate seem to have similarly priced 9GB 10K
RPM solutions.
Thanks for any help / comments

I think you mean ASUS P2B-DS (just me being in the mood for

considered about 15 months ago (I finally setteled for the

But the power loss over the power supply also gets
dissipated as heat (put your hand on one after switching
off a machine that has run for some time, and you'll notice
it feels warm, depending on the load you're have been trying
to extract from it; if it feels hot, though, it is probably
time for a new one).

I'm looking for a cheap solution with Win9x/Linux support.

Here are several possibilities:
SCSI drives are quite intelligent. { The newest EIDE drives are
catching up to them. } One of the capabilities of the drives is to
continually move the heads around so that no particular cylinder has
the heads flying over it all the time. That is probably the actuating
noise that you hear. Also, SCSI drives tend to reorganize themselves
when they aren't otherwise occupied. It could be the SCSI controller
on the drive testing a cylinder/track/sector for errors, or the data
simply being defragmented.
On the OS side, do you have a printer d�mon running? It does check
the spool directory to see if any files have been added for printing.
The frequency of the checking can be altered, but I don't use lpd, so
I can't tell you how.
On the network side, do you have any shares in effect TO your SCSI
drive? Could be the other system checking the status of your drive.

Ray
