I have the same MB/CPU combo (running ~374 right now because it;s 35C with
no air conditioning in the house :(
My only complaint is that I cannot get PS/2 mice to work properly off the
PS/2 port on this board.

Reply-To: [EMAIL PROTECTED]
I have one of those CD-ROMs that shipped a long time ago with the Sound
Blaster Pro in a "multimedia package." It works with the sbpcd driver.
When I manually eject a CD from it, it doesn't seem to notify CD player
programs. Also, if I click the 'eject' button on one of my CD player
programs (because this usually has the side-effect of scanning the tracks
of the CD), the CD player program hangs hard so that I cannot kill it
with any signal I send it. I guess it's stuck in select() or something?
Anyway, once it hangs, I cannot start another CD player program until
it's gone, and I have to reboot to get rid of it.
Does anyone know what's causing this? Is it a bug in the sbpcd driver
or could it be that my CD-ROM is defective?
Something that might be important is ... what's the role of that thin
4-wire cable from the CD-ROM to my Sound Blaster Pro? I've closed my
computer's case on that thing a zillion times by now so it might be a
little mangled. Might the sbpcd driver hang waiting for a signal from
the CD-ROM drive that comes on that cable? Maybe the signal never arrives,
if I've ruined it....
Any tips would be greatly appreciated!

Subject: dual celeron... for me?
Date: Sat, 19 Jun 1999 07:30:07 GMT
I have been seeing all the talk about dual celeron systems, and saw that
abit has a dual-370 board on the market now, and I was wondering if anyone
out there has first hand experience with a dual celery system?
I am interested in doing this myself becuase I as a user I am not so much
concerned with the max fp score my system can obtain so much as how fast the
system actually responds to actions (ie, opening Emacs, switching desktops).
Also, I run a proxy server setup through my system, and I know that in that
situation, a dual processor system would perform better than a super single
processor.

Depends. The IBM /AT&T specifications for serial ports originally
did suggest having the IRQ lines XOR'ed . Unfortunately, most
HW manufacturers completely ignored this and therefor two serial
devices will not work one a shared IRQ line on most PC motherboards.
Newer boards have now started to implement this , so if you're lucky
and use a recent kernel (2.2.*), then you might want to try it. There
is a separate kernel option for allowing shared IRQs, but please be aware
that it depends from the HW used whether it will work.

It is. This happened with nearly all 386/486/P boards, therefor the
standard solution for people with a need for more than 2 serial devices
was getting either a separate controller card or using an intelligent
multiport card (AST, Cyclades etc.) for this task.

Though it was far from an ambitious project like this, around five years ago I
used a 55SX in serial communications. That model had a modern UART. The serial
port was not the bottleneck in system performance - the hard drive size/speed
was.

Subject: HELP ! verrry slloooww reading DAT tape
Date: Sat, 19 Jun 1999 11:29:17 GMT
Hi,
I have received a number of DDS-2 tapes that I have to read. They are
written on an AIX system. The format is 1024 bytes per block.
I have used the "mt" command and set "defblk" to be 1024. Now when I
"tar -xvf /dev/st0", the tapes read at about 5Mb/hr :(. Life is too
short for this.
I am sure that I have missed something fundamental. When the tape reads
it says blocks = 2. I have tried the -b command to read more blocks at a
time but it makes no difference.
Can anyone send me some suggestions as to what I can do to speed this up
a little.
My system: Dual Intel Pentium 133 / 64Mb / 2 x 4Gb Quantum on an AHA2940
/ Sony SDT-5000.
Kind Regards
Chris Wilson

Yes, I know. Therefor I put it before a terminated drive (an IBM 2ES
DCAS-34330W). If that drive hasn't active termination I can understand
my problems but it has, I think. At least it is terminated.

The problem as I see it is that the good sound cards (I use event Gina

Well, if you're really adventurous, get your hand on a DEC Alpha
Multia. These were the earliest Alpha so you'll be getting a 64bit
machine. The cases are about 2.5" high and the size of a medium pizza
box. Everything is built in including ethernet, vga, serial, parallel,
scsi, two pcmcia slots.
Plus you get to try other Linux port besides plain old i386. Lilo will
never look the same after your try the ARC console and Milo in the
Alpha.
BTW, a 166Mhz Multia has speed comparable to a Pentium 100, although
it excels at FPU.
You should be able to pick one up for about $100.
Dang.

in the 2940uw installation manual they say you can only have 2 of the
3 (2 internal, 1 external) connections attached to devices
i tried attaching all three on several machines one worked (at least for the
limited
time that i tried it) and the rest didn't
however the card i now have is a 2940u2w
the manual doesn't state any such limitations
this card has 3 internal and 1 external connection
i am using 2 internal (uw scsi 68 pin, and scsi 50 pin not using the u2w)
and the external uw (or u2w)
i have heard that adaptec has a firmware revision for the 2940uw
to allow all three connections to be used, but i haven't checked it out
