Plutao,
Well I can help a bit here. If you go to http://www.corsairmicro.com/ and
select Compatibility Lab, you can select various motherboard makers and
models and see what supports ECC that way. I know Kingston has a similar
feature at their site also.
RedHat supports most of the more common M/B chipsets.
Good Luck,
KW

You should probably start out with the book "Building Linux Clusters".
Not exactly the definitive work on the matter, but it will at least get you

Subject: Re: UPS selection
I don't know about USB, but I have a Belkin FC625 that I'm very happy
with. Plugs into a serial port to monitor line and battery state.
Although you can use the "modem control signal" connection method, this
UPS can be interrogated using real serial data on the port too.
I'm using "nut" to monitor the UPS and shutdown when the battery becomes
critical. Nut takes a bit of configuration, but once done works very
nicely. (Note, use the nut "trust425+625" driver for this Belkin UPS).
The supplied serial lead work perfectly with my system, so there's no
cables to make up.

Subject: Unwanted Power Saving Under 2.4.0
Date: Mon, 29 Jan 2001 21:34:57 +0000
Reply-To: [EMAIL PROTECTED]
Hi All,
Am running LM7.2 with a shiny (almost) new kernel 2.4.0.
Mainboard is an MSI K7Pro (6195).
The problem is that after a short while of inactivity the
console blanks (fine). After a bit longer though the
system goes into a 'deep suspend' (not a crash). It is
woken again by a mouse movement or other interupt and
resumes fine.
The problem is I only want the console blanking. When the
system suspends no processes are run, including dnet,
which is doing nothing for my ranking! Furthermore,
the software clock stops during the suspend and resumes
having lost the time. The hardware clock is naturally ok.
The mainboard has both APM and ACPI onboard and I tried a
kernel with both compiled in. APM appears ok but the ACPI
table signatures were bad so it wasn't used. The problem
persisted with APM so I took it out.
The problem I now descibe is with a kernel with NO power
saving features compiled in or loaded as modules! I
therefore wonder if this is desired behaviour or not.
Under my previous 2.2.1X kernel the console blanked but
didn't suspend quite so deeply that dnet didn't process.
Any help / advice appreciated,
Jim

Yes. There's drivers at http://v3tv.sourceforge.net, but they are VERY
unstable. And they are not even released yet. If you have CVS, you could
give the drivers a try, or better yet, help with development :-)

Eh? No. Nowhere near!
They may accept the same instruction set, but the architecture is
completely different, The 686 line in particular is basically a risc
superscalar design, with twin pipelines and incoming i386 instructions
being converted to an internal instruction set which is then optimized
as it arrives, with out of order execution and so on ...
Cisc outside, risc (by any other name) inside, and delayed out of order
execution with dynamic optimization is hardly "basically 386".
A real expert will tell you more. I've forgotten everything I ever knew
about microprocessor design (i.e. some of the above may be faultily
recalled too!).

I dont know whether I didnt make my question clear or my question was

anyway, I tried to recompile ALSA with debug mode on (as it is said in
it's installation) but nothing wrong with that
the problem is when I try to modprobe snd-card-461x even with modified

my question now is: how can I make use of snd-461x with or without ALSA?
and my 2nd question is: how can I remove ALSA permenantly from my linux

By default Linux (and OS/2 and maybe DOS) use "polled" printing. They send
a chunk of data to the port and then start repeatedly checking to see if
it's ready for more. If you specify an interrupt then Linux doesn't come
back to the printer port until the port triggers it's interrupt. This makes
printing somewhat faster and doesn't slow the rest of the system down so
much while printing.

This may be what you meant by "lighter weight" but I think the fact that you
can run Linux "headless" (ie. no monitor, keyboard, mouse) would be an
advantage. I know some people manage this with Win. but every time I've
tried it I end up having to plug everything back in just so I can click OK
on something or another. It's pretty hard to screw Linux up so bad you
can't telnet into it and if you do you can just plug a laptop into it's
serial port (laptops are way more lugable than monitors).
As for PCAnywhere, you should look into VNC. It's free, good, and available
for both Linux and Win (and others). If you'll be accessing it remotely
then Telnet & SSH are way faster than PCA or VNC.
I don't know much about webcams but Linux seems to be pretty good at
automating tasks. Lets say that in addition to whatever else you are doing
with the video stream, you want to take one of your frames each hour, turn
it into a jpeg and email it to yourself. In Linux that should be a simple
cron job shouldn't interfere with your main stream. With Win. you'd
probably have to log in and do it manually each time and hope the video
stream doesn't show up on your desktop otherwise PCA will slow to a crawl
trying to keep up.

When it comes to physical objects like hardware, you get what you pay
for. Cheap hardware causes *MANY* problems, and if you're new to Linux,
you may give up in disgust as your cheap system crashes, hangs, and
freezes unpredictably because of hardware flakiness. Been There, Done
That, Never Going Back--and the "cheap" system was from Gateway, a
"major" manufacturer who refused to believe that their hardware was
br0ken, and claimed my problems were because I installed an unsupported
OS.
Stay away from HP, Compaq, and Gateway. HP's consumer-level x86
machines are put together with shoddy components. Similar story for
Compaq; in the old days they sold machines that took parts that were
very slightly incompatible with standards, and you could only buy
replacement parts from Compaq at vastly inflated prices. See above for
Gateway.
>From what I've seen, Dell's desktops are *slightly* better. Then again,

Avoid anything with RAMBUS or an i810 chipset. Find someone (not a
salesperson, a hardware geek) who knows what's what and ask their
opinion on a couple of your top choices. Better yet, build your own box
from parts. The quality will be far greater, and you'll learn a lot
from doing it. Or have a local geek put together a box for you; you can
often bribe them with beer and pizza especially if you live near a
university. There's a guide at http://ars-technica.com/ somewhere and
it's not nearly as hard as it sounds. HTH,
