Kernel versions 2.4.x support ACPI (or at least have a configure option for it,
I don't know if there are user space programs you need to install as well).

Subject: 3com 3c515 request for help
hello one and all,
i humbly request a little help and guidance. i have a pure isa 486 with a true
3com 3c515 isa 100base ethernet. i installed a new version of redhat linux 6.2,
kernel version 2.2.14-5.0. i have been trying for three days to get linux to
recognize the 3c515 card, but it will not. i have set the eeprom settings using
a dos bootable disk and the 3com 3c515cfg utility. i have tried many
configurations, and the current is set at ioaddr=0x280, irq=12, and dma=5. the
3c515cfg utility passes the testing. so i know the board works and the settings
are coded in the eeprom.
i have conf.modules containing "alias eth0 3c515" and "options 3c515 debug=1
io=0x280 irq=12". with the eth0 adapter loading on bootup. but it always
fails, no matter the hardware settings. in fact, bootup returns that "Delaying
eth0 initialization."...a message from ifup via ifconfig.
i have also tried "insmod 3c515.o" and that always returns "0 3c515 cards
found" and "3c515.0. init_module: Device or resource busy"
so i can not seem to find the problem and debug it out. can you please pass
along some suggestions. thank you in advance and have a nice day.

Are you sure? I have a RAID 5 array sitting under my desk, consisting of
only 4 drives (and one of those is a hot spare), and those are only 9 gigs.
Not the latest, greatest by any means. Yesterday I copied a few gigs from
an IDE drive to the RAID array under Linux, and even though the IDE drive
was at full speed reading, the RAID array was only active about 1/2 of the
time writing. If it will *write* twice as fast as my IDE drive can *read*,
that's pretty fast.
Granted, it's not as fast as simple striping, but you make it sound like
it's going to be abysmally slow, which it won't. It should still be faster
than a single SCSI drive, and simply blow away anything from IDE.

Try having 5 or 6 programs access the IDE system at once. Compare to the
same under a SCSI system.

I won't get into arguing about symantics, but I've used IDE and SCSI in
areas where there are multiple programs accessing the disk at once. SCSI
blows away IDE in terms of responsiveness and throughput. That's all I need
to know.

Hi,
On a system with hardware RAID level 5, booting Linux on RAID devices, if
one drive fails, does the system boot, before replacing the drive? (not
hotswap)
And if instead of RAID level 5 we have a level 1 (mirroring)? Does the
system boot if one drive fails, before replacing the drive?
Does the rebuild, after replacing a drive, allows booting the system w/o
problems? In both levels?
Thank you for your time!

Hi,
It is some days ago, I know that. I use the 3Com 900b COMBO, too. You need
the 3c59x driver. See also
/usr/src/linux/Documentation/networking/vortex.txt
There you get answers on how to tell the kernel which Port you want to use.
Example modules.conf:
alias eth0 3c59x

Subject: HELP: Need help for soundblaster live card on redhat linux 6.2
Date: Wed, 28 Feb 2001 10:20:38 +1100
Hi all
I am having some problems with SoundBlaster live sound
card on redhat Linux 6.2 running kernel 2.2.14-6.1.1. It is
using the emu10k1.o diver.
My problem is that the card can play .wav files very clearly and
cleanly, but when I try to play raw mu-law files it plays them with a
lot of distortion. Yet I have played the same audio files (raw mu-law)
on a windows PC and it plays fine, so the audio file is not the problem.
I have tried using the sndconfig utility and it plays an audio
message and again it is distorted. As I mentioned above, the audio
that I have assigned to system functions (like when you delete a file, etc)
play without any distortion.
Can anyone offer any help. I have had previous experience with SCO, BSD
& AIX Unix, but I am relatively new to the Linux scene.
Thanks in advance.

Yes, thanks.
I can do everything up until the edit 'lilo.conf' part.
How do I edit the file when the system won't boot to Linux. The boot
disk that was made during the installation is worthless. It gives an
error of '0x10'. I've never gotten a Red Hat Linux boot disk to work
for me, by the way.
The installation CD has a 'rescue' feature. But I can't do much with
it, let alone edit a file and run 'lilo'.
After editing the file, I need to apply the changes by running 'lilo'.
What I need to know is how to make the changes to '/etc/lilo.conf'...
Thanks for your help so far..!

My system had severe problems with DMA enabled when using a 2.2.18
kernel patched with the then current IDE driver (as provided with Debian).
With a simillarly patched 2.2.17 kernel there wasn't a problem. I'm wary
of running 2.4.x until I can guarantee that the problem is resolved - I
don't want to have to reinstall yet again.
I'm running a fairly low spec 82C586 based system, only capable of running
at ATA33, although my drive (a WD205AA) is capable of ATA66.

Casual use does not equal laziness. These issues are only relevant when
the situation calls for it. When you can do a clean install in less than
a half hour these days, and that's all that matters to you, then these
things usual aren't issues.

Yes, it tells you about the issues. I'm not arguing that. I'm arguing
the relevance to home users who like to keep up on the latest software
and hardware drivers and only have to worry about themselves, not a mess
of other users.

But the argument is for home users who usually have one box.

Maybe I should have put more emphasis on the "newbie" although I hate the
associated stigma(s). How many will know what to do when partitions are
truly fscked? And even then, how many will pass up a super-easy clean
install?

I can see this if your arguments included things like search time and disk
spanning, but the argument assumes one, maybe two, harddisks where speed
is dictated by your hardware -- IDE/SCSI, RPM, etc -- and are increasingly
less of a problem.

You mean to tell me you think everyone (read "home users") routinely backs
up everything and not just what's most precious (e.g. love letters and MP3s)?
You've got to be kidding. If that were true, I'd think these newsgroups
would have far fewer posts. This is not a slam on my fellow users, but I'm
trying to be realistic.

But you're just proving my point. Why back up anything other than that?
Hence, why partition anything beyond that? I admit I didn't originally
include /var as a seperate partition, but OK, sure (/etc notwithstanding
for reasons we both know -- /etc partition bad, bad!).
If any other sorts of partitions such as /usr get hosed and you're going
to replace via the distro., then why have many partitions in this setting?
Please point out what I'm overlooking (<excuse>my eyes are glazed over from a
long day</excuse>). Where is the problem given this specific user setting?

OK, granted, but IMO, we're not talking about the stable, functional, high
usage home that we want to take good care of. We're talking about the vacation
home that gets used when you have free time. Unless you've got money to burn,
that one room shack does just fine. Little maintenance, no worries, gets the
job done, and is functional for it's primary purpose given the time spent there.

In that case, yes. But beyond that, the need is arguable.
To me, backups serve two purposes: (1) save unreplaceable data, and (2) cut
way down on restoration time in the event of data corruption or loss. We
take care of #1 by backing up /home, /etc and maybe /var. #2 is taken care
of via the multitudes of slick, fast and easy installations care of our vast
selection of distros. Now, couple on the partition argument at hand. Your
precious data in /home, /etc, and /var are isolated from the corruption of
other partitions (or partition in my view). You said yourself the rest is
taken care of by the distro. Hence, why break up what's left? Remember, I'm
not talking about servers and multi-user (as in humans, not daemons and other
processes) systems; I'm concentrating on Joe Linux.
Phew! Have I gone completely OT on this thread or what? I hope I didn't make
the poster who started this thread regret it :-)

Go to http://opensource.creative.com, try the latest cvs. Be sure your
kernel source is installed and also configured to match your current
system, since this alters some of the headers. If you still have
problems, go to the devel mailing list that is also at the above URL,
describe the problem and your hardware when doing so. The driver and
mixer support changes a lot.
