I got those massive CPU fans from ComputerNerd, the motherboard is packed.
Ordered a full tower ATX case with 300W power supply from www.pcbroker.com
for $75. I think this will be sufficient for most of the time. However,
CPU idle matters on the question should I turn the computer off when I'm
not using it.

The modifications were made by my dentist father. (He's good in drilling
small holes.) The CPUs from ComputerNerd are pretested and guaranteed to
run at 464mHz, hence the small premium in price. Voltage was upped, too,
to get them running at 504mHz. Intel accidentally made a pretty good
chip.

I've been told (original source is Raimo Koski's book) that Linux can read
from both IDE ports (abuse of terminology?) simultaneously. This would
make it faster to have half of the swap space on the other disc. Also,
for most disks reading is faster from the beginning of the disk (i.e.,
outer cylinders at, say, 3.5Mb/s for a particular disk) than from the end
of the disk (inner cylinder at, say, 2Mb/s). The same source indicated
that seek time is shortest in the middle of the disc, but that this is
less of an issue with the swap space. This would suggest making both
drives masters (as you suggested) and put half of the swap space on each
disk.

www.1stchoicememory.com claims that their memory is true PC100, not some
reprogrammed slow chips. I called them and asked, and they at least knew
the answers I wanted to hear.

That's a good tip, the compiling test. Can software somehow detect
possible memory errors? In Windows NT, the OS keeps some sort of a log of
memory errors. Is this only for ECC or all type of memory?

There was another poster claiming to have found a solution to the problem:
"I am using ia MS intellimouse and I am using the hacks for the scroll
wheel under X. The wheel acts as both a button and a wheel with the
hacks I got from http://www.inria.fr/koala/colas/mouse-wheel-scroll/
You can get more info there."

I like the accuracy of SUN's optical mice. On the other hand, my MS mouse
feels really good now. That is, after I bought "3M Precise Mousing
Surface." That was the best spent $5 ever!

If you get an answer that works, please notify me too.
I've got the same card, and actually had it working for a few hours.
Ever since, though, I get a message something like:
pcnet_reset_8390()
Something about it not being able to reset. This is shortly after
it loads the drivers for the card.

Is the Adaptec 2940U2W SCSI-adapter supported under Linux (2.2.x) yet ?
I want to buy a Asus P2-DS mainboard which has this controller onboard to
connect a Quantum 9.1 GB U2W-SCSI Harddisk on it but
I need to be sure that I'll have a fair chance that it will work.
(Otherwise I would have to buy an extra IDE harddisk and that would slowdown
performance)
Anyone has experience with this configuration? Mail me or post a message....

Subject: can not install Linux: CD-ROM-Problem with Debian 2.0r3
.
hi, can U help me?
I want to install debian Linux 2.0r3 on my old 486-33.
I have this old SONY CDU31a CD-ROM drive.
I read on HOWTO-CD, that debian supports this proprietary
CD-ROM-interface, and found drivers(c-source-code) on the Web.
When I tried to install linux I did the following:
- boot from DOS-floppy with a DOS-CD-ROM driver.
- start the installation from CD-ROM, partition the harddisk, etc.
- but if I get to the step of installation where Operating Kernel and
Modules should be installed from CD, the program asks me to choose the
type of my CD-interface.
- SCSI and ATAPI (IDE) does not work (of course).
- If I choose "proprietary CD interface", the program asks me for a
driver on a floppy, but i have only this driver in source-code on my
other PC(win95)??
How can I get this thing work?
please leave me a mail: [EMAIL PROTECTED]
Thank you
Christian

For the 3ComImpact IQ, you need to set register 80 to 1 (ATS80=1) which
controls MultiLink-PPP. Also, are you using PAP authentication? My ISP
will allow both PAP and name/password, but would not do ML-PPP with
name/password. Once I set up PAP it connected both B channels.

Hi,
I have PartitionMagic 4.0 from PowerQuest. It can work with linux
partitions (including swaps) and fat16, fat32 and NTFS partitions. I used
it to setup my linux partitions, and when I installed Suse 6.0, I didn't
have any problems. Fdisk can be dangerous to use (or at least it can give
you a headache). Partition magic can resize and move partitions around
without erasing the data on them.
I recommend Partition Magic, especially for dual boot Linux/Win machines.
