For the Standard 8 Bit Timer Mode, the best approximation is 41667 Baud.
Baudrate = Fosc / (192 * (256 - TH1)); TH1 is the Timer reload value
(254 in this case)

Hmmm strange I thought for quite some while that vmware killed it. But now I had
lockups without it. Do you use APM?

No it can't. You'll need to download drivers for these:
for sound, go to http://www.alsa-project.org/
for video, go to http://support.intel.com/ and look for the i810 linux
driver

You generally get what you pay for, and manufacturers put the cheapest,
nastiest parts they can into their low-end all-in-one motherboards. If
reliability is a concern, bite the bullet and buy good components. Any
other route leads to hardware failure, madness, lots o'wasted time, and
spending even more money to recover from the first bad decision.

Guven Linux can use the 2.4.0 test kernel quite happily. Check out the kodak
digicam howto at linuxdoc (www.linuxdoc.org) for details on setting up usb
on linux. Getting it to work in a very small amount of space might pose a
problem because of the kernel, and any libraries you might need. If you need
a hand with the embedded system, feel free to e-mail me.

Does anyone know about installing the abit Hot Rod card under Mandrake ?
Anything I should know about ? I'm aware that configuring the HPT366
chipset can be trickey, and there's plenty of info on installing abit
motherboards with that chipset, can I base my install on those
instructions or is there something else I need to do because this is a
card ?

Maybe it's the firmware? I have the 2.0. 1 (I think) version
but have just downloaded .3, although I haven't installed it
yet.

I've done all that and there are no errors. Last night I
unticked 'enable software compression' and ticked 'only
connect at' setting it for 38400 after trying different init
strings that did no good at all. I managed to stay connected
for over 2 hours in windoze after doing that, untill I chose
to disconnect, but I'm now having difficulty getting the
modem to respond. Just before the longest session ever last
night I couldn't get a response in either Linux or Windows,
then I switched the modem off, rebooted into windows with it
on, and it stayed connected until I wanted to go off-line.
Then I went to Linux where it wouldn't respond at all. This
morning it worked in Linux with the speed reduced to 38400
but was very slow. Just now I connected, got disconnected
before I could log on to my ISP, had another go and was able
to actually get 38400, but the modem was still sending after
I exited the ftp app I was using. I disconnected, tried to
reconnect, and got a 'modem does not respond' again. I'm
starting to wonder if I do have a fault in my modem, cable,
D connector or port.

Thanks for the encouragement. It is annoying having to use
my old winmodem most of the time. If things don't improve it
seems as if I'll have to get another modem. I didn't need
the external one before I started using Linux 2 months ago
and this is driving me mad. The modem in question is about 2
years old, from the days when you had to flash upgrade to
v.90.

Subject: Advice for Win/Linux PC hardware?
Date: Sun, 11 Jun 2000 04:44:09 GMT
I'm a programmer, not a hardware guy, but I just started a new job, and one of
the things I need to do is buy three PCs that will run Linux as well as Win98,
and probably Win2000 or NT. Following some pertinent info, I've got a few
questions that I hope somebody here will be able to help me with...
Applications to support are: Web design, desktop publishing, scientific data
analysis (statistics and graphing), as well as regular office stuff.
Each PC should cost no more than about $1500 US.
Core (most important) requirements: -- good quality monitors, at least 17",
but 19" would be great -- decent video card, probably 16 MB -- 128 MB of RAM
-- fast cpu, with no compatibility gotchas (My boss is paranoid about
non-Intel chips, and I don't know whether he should be or not. He thinks we
should buy PIIIs.) -- fast harddrives (thinking of 3: 1 for swap space and
temp storage, 1 for Win, 1 for Linux) -- fast, reliable network card --
CD-ROM drive -- 3.5" floppy (but ideally one of those Imation multiformat
drives--don't know if Linux supports them) -- USB, serial, parallel ports --
bus and memory as fast as possible -- ergonomic keyboard and mouse -- the
more open slots and bays, the better -- a Windows OS
Some wish list stuff, that will otherwise be in addition to the $1500:
-- SCSI for at least one PC, maybe two
-- CD Writer for at least one PC
Some other definite purchases in addition to the $1500:
-- 1 tape drive for backup (am assuming that I'll need SCSI for this)
-- 2 smart UPS
-- 1 external modem
I *don't* need
-- internal modem
-- sound card
================
Questions:
1. What's the best system I'm likely to get that satisfies the core
requirements while staying within the $1500 limit? 2. I have limited
harware tinkering ability, but I can install and configure stuff like
harddrives, cards, RAM, etc. Is there a barebones system I can get that I
could add onto to get the setups I'm looking for? 3. What, if any, is the
probable difference in $$$ I'd pay by going through a local shop to
custom-build these, as opposed to buying on the 'net? 4. If I did want to
buy online, who has the best deals, but is reputable? 5. Any ideas on
individual components, keeping in mind the compatibility issues?
Thanks for any suggestions!

Then you're looking at something extremely difficult, believe me I'm talking
from experience. The easiest method would be to look at the different
howto's, in particular the lfs (linux from scratch) and boot disk howtos.
Try and imagine something in between. It's probably easier to do something
based on debian than RedHat as there's more documentation around. Look at
things like small linux, lem and lineo's linux implementation, but I've
found that lineo's tools tend to return slightly different results in
scripts, especially in ash than you'd expect in a standard environment. Mu
linux is a good example of how tools can be made smaller but with no real
shortcuts. I would give you some urls, but I can't remember them, so you'll
have to look yourself. If you need any help with the project get in touch
with me, and I'll see what I can do.
