Subject: Trouble with playing audio cd's but can mount/read iso9660

I've come upon a strange error recently. I've updated my kernel to
linux-2.2.17 and moved around drives inside my machine several times, so
something may have changed that I've missed.
Nonetheless, I am able to mount iso9660 filesystems and read data, however
I am unable to play audio cd's. When I try to play an audio d with
'cdplay' I get the following error:

I haven't been following new hard drive technologies for quite some time.
I need to get a new hard drive, though, and I'm not sure what kind I can
use in my system. I have an Adaptec 2940UW controller, a basic "standard"
ultra wide scsi controller.
Now perusing the SCSI hard drives on pricewatch, I don't see any drives
that are just an ultra wide interface. There are things such as fibre
channel, sca, lvd, differential, ultra 160, and maybe some others I'm
forgetting.
Am I strictly limited to 68 pin ultra wide scsi drives, or are any of the
ones listed above (or in general) also compatible with my controller?
And while I'm at it, what's a good quality model of drive to buy? I'm
looking in the 9.1 gig catagory or so.
Thanks,
Matt

Don't know if this will help. We have an IBM RS-6000 here with serial
printers. It has a multiport serial card and is attached to a hub which
takes RJ45 connectors and UTP cables which then go through the building to
the printers.

Doesn't seem to be a problem with the drive - I've already tried 3
different ones, as well as different floppy cables. Also, it doesn't
give the 'Diskette error' message when there's a bootable floppy in the
drive - it seems to boot normally but then stops. I think that it's
reading the boot sector of the floppy, but then not finding the setup
program it's looking for and so stopping and not being able to continue.
I'm pretty sure by now that a plain boot disk will not boot this
machine, it needs the specific setup disk.

Except it doesn't seem to have Phoenix or Award BIOS. Says 'Reply

I personally have the Abit KT7-RAID... it runs great... you might want to get the
non-RAID version (plain KT7) if you're trying to save money... I'm pretty sure
Compuplus (www.compuplus.com) is selling them for just under $150...

Are you running the hard drive on the RAID controller or on the regular IDE
channel? You have to put it on the regular IDE channel to install, then patch
and recompile the kernel to get it to recognize the RAID... patch is available
from a link off HighPoint's website, http://www.highpoint-tech.com
If that's not the problem, then I have no idea :-)

I have an Abit BX6r2 that detected 64MB when I had 640MB. Abit
released new BIOS firmware; the release notes mentioned something
like "Fixed Linux memory detection".
Your BH6 may have similar problems. Check for BIOS updates. The
'append = "mem=192MB"' option should also work.

Going to be doing this shortly. I just upgraded the BIOS less than a week
ago, so I don't think that is the issue - unless they broke it again! : )
Many thanks to everyone. I've been using PC's so long I feel foolish asking

As everyone else has mentioned, the VX won't work well with more than
64MB. Take half of the memory out, and use this motherboard for
something other than your main desktop system. It's more powerful
than you need for a firewall, but if you don't have one, consider
using it for that. Or mail, DNS, whatever.
I have an even older HX motherboard, an ASUS P55T2P4. The HX supports
512MB, though I only have 64MB in it. An undocumented jumper
combination set the core voltage correctly for a K6-2/400, which I
couldn't resist for $42. With a big, cheap IDE drive and FreeBSD, I
now have extra storage space usable from my desktop with NFS or
SAMBA. It's not UDMA, so it's slow, but still worth having. My old
2X CD burner lives there, too. I can back up my other systems to the
file server's drive, and then burn CD's later.
It's also nice to have a 'play' system that doesn't need to work. Try
all of the distributions. Try FreeBSD and OpenBSD. Take a few
chances, try ideas out, break things and learn why they broke.

NS possibly didn't "crash", but is just trying to resolve addresses.
Check your DNS settings (/etc/hosts, /etc/route.conf, /etc/resolv.conf).
And of course upgrade to a newer version of NS. 4.61 is rather old.

doesn't work
Date: 11 Sep 2000 23:32:22 -0500
Reply-To: [EMAIL PROTECTED]
I have installed DOSLinux (a looplinux setup assembled by Kent Robotti) and
it works very well. Everythings works fine EXCEPT one thing.
DOSLinux is installed in a loop filesystem stored on a Windows 98 machine
VFAT partition. If I shutdown Windows and reboot the machine, pressing F8
during the bootup, escape to "Safe mode command prompt" and run the batch
file to load DOSLinux, everything works fine. However, if I choose the
"Restart in MSDOS mode" option and run the looplinux batch file from there,
it all works fine, EXCEPT that the network card doesn't work (in Linux).
When I do the "ifconfig" command to setup the ethernet card, I get the error
message "Resource temporarily unavailable" and there seems to be nothing
that can be done to get the card working again other than to do a full
reboot. It seems like somehow Windows is not letting go of the card when it
goes into the "MSDOS mode". It seems to me that there ought to be some kind
of utility, either for DOS or for Linux, that could be used to reset the
card and make it start clean. If I had a DOS util, I could put it in the
batch file that starts DOSLinux - if I had a Linux util, I could put it in
my startup scripts before the call to "ifconfig".
The machine is a standard desktop machine, with an NE2000 compatible, PCI
ethernet card. Does anyone know if such a util (to reset the card) exists?
It would really be a lot more convenient for me if I could boot it from the
MSDOS mode instead of having to do a complete Windows shutdown.

(Note, I work on GCC and not the Red Hat Linux release, so don't take anything
I say as gospel for Red Hat Linux).
I've been using an LX440GX+ for a dual processor setup for about a year now as
a high end workstation (not a rack type server). The basic motherboard works
fine, as does the builtin ethernet and Adaptec 7896 dual channel scsi
controller, and you get plenty of PCI slots. The major thing that causes grief
for me (and I'm contemplating switching motherboards because of it) is that it
has a builtin video card. Now for a server, thats fine and dandy, and Linux
does indead support the card. However for a workstation, it is kind of deadly,
particularly if you want to put in your own video card (first of all, no AGP
slot, second of all, the Red Hat Linux installer got rather confused with
having 2 video cards, and it is kind of messy to recover from this if you
aren't experienced at hacking installations).
I also got bit by another feature of the board (again for a server it probably
won't matter). I've been having tape drive problems, so I bought a cheap IDE
disk to back everything up to. When I put in the IDE disk, the BIOS has this
little feature that you can select which disk is the boot disk, which I missed,
and so I thought the IDE disk was going to be the first disk (with all of the
SCSI disks being 2nd, 3rd, ...), but instead the BIOS kept the SCSI disk as 1st
disk, which result in my losing my root partition, when I tried to install
Windows on the empty IDE disk.

In general, newer drives of the same interface type (e.g. SCSI) will
"fall back" to whatever your card supports. So, a 68pin U160 SCSI drive
will work for you.

In general, a newer drive will "fall back" to the level of support your
