What kind of speakers are you using?
Would you know what the power output of your sound card is in watts rms?
I assumed that conventional audio cards can not drive ( unpowered ) hi-fi
speakers,
But, maybe I'm wrong - can you fill me in a lttle bit - Thanks.

Hi,
I ran into this myself a few weeks ago. I followed the same instructions
you did and without success too. The compile in recommendation is good
advice, but you can also get the module setup to work in RedHat (6.2 for
me) by adding this to your
/etc/rc.d/rc.local file
modprobe ide-scsi

you might consider getting an ultra-ata 66 controller card, such as
the promise 66, or any of the others supported by the patched linux
kernel. you DID patch your kernel for ultra-dma 66 support right? if
not, try that first of all things.

Date: Wed, 5 Jul 2000 16:58:40 -0700
I just built a PC using an ASUS K7V motherboard (Athlon CPU). ASUS 6600 video
card (nvida 256), and other hardware. I have stayed with the default bios
configurations.
Are there any optimizations that can be turned on/off to enhance performance
with Linux? Or is there a web site with configuration info for these kinds of
systems?
Thanks,

What exactly are you trying to optimize? Is this a personal workstation,
a web/fileserver, a router/DNS box, what? Without more info, all I can
suggest is these things:
"man hdparm" to get your drives going faster. "hdparm -c1 -u1 -d1 -m16
/dev/hda" can boost the performance of /dev/hda by as much as 40%.
Compile your own kernel, entering "PII" for the CPU type (for the 2.2
series) or "Athlon" for the CPU type (for the 2.3/4 series). Most distros
ship kernels compiled for the 386, which is not quite as fast as a kernel
tweaked for your particular CPU.
Check out Xfree86 4.01 from http://xfree86.org/ , which might up the video
performance.

Subject: Ricoh MP-7080A vs. cdrecord
Date: Thu, 06 Jul 2000 10:43:31 +1000
Hi all,
I'm having a few problems getting my new Ricoh MP-7080A cd burner
working under
Debian unstable. I'm 99% sure the kernel config, etc is ok - it's a
stock 2.2.15 kernel
with the reiserfs and enhanced IDE patches. I'm using the ide-scsi diver
for the cd burner and can burn audio cd's perfectly. Problem is that
burning data cds hangs the
system !?!?!! The cd burner is attached to the HPT366 controller of an
ABIT BP6 motherboard, I've tried cdrecord 1.8, 1.8.1 and 1.9a3 to no
avail...
Has anyone else experience problems/success/anything with this drive?
Does anyone have
any idea why I can burn audio but not data?
cheers,
James

For the serial cable, there are Mac/PC serial cable adapters. You might
want to check with one of the Macintosh mail-order outfits, like
http://www.maczone.com, or with a specialty parts outfit, like
http://www.computergate.com. I've no clue about the power supply,
though. AFAIK, that's NOT part of the Mac serial interface.

I was just in Micro Center today, and I saw somebody at the checkout
with an optical mouse from one of the "almost generic" mouse
manufacturers -- Inland, I believe. A search for "inland and mouse" on
http://www.google.com turned up a bunch of hits, but none obviously for
the manufacturer on the first page. The mouse I saw looked pretty
similar to Microsoft's model in terms of shape and styling, but the
price tag read $30.

Perhaps a theoretical small advantage in that you don't have to go
through the emulation layer in order to get data into the system.
However, with all real-world CD drives, the bottleneck in accessing
data is the data of the drive itself, not the speed of the driver.
I have run CD drives both ways and could tell no difference.
> Is there any such thing as an

There used to be; I doubt you could find them anymore. Look in the
kernel configuration under "non-IDE, non-SCSI CD-ROM drives". There
are roughly a dozen different drives and/or interface cards that
are supported.

It would surely make life easier for us who have IDE CD burners, but it
might be a bit of a pain for those with SCSI drives. I've no experience
using a computer with IDE and SCSI drives, and I don't know how well
a "real" SCSI driver would coexist with SCSI emulation.

Subject: scsi tape drive locks up system
Date: Thu, 06 Jul 2000 01:25:39 GMT
We are running RH6.2 with a 2.2.16 kernel on an intel with one scsi
adapter, adaptec 29160, two harddisks and a tape drive (Seagate Scorpion
40). We dumped two filesystems on one tape with
dump -0 -a -f /dev/nst0 /
dump -0 -a -f /dev/nst0 /home
which seemed to work fine. A subsequent
mt -f /dev/st0 rewind
mt -f /dev/st0 status
worked as well. Then we wanted to add another dump to the end of the
tape and did a
mt -f /dev/nst0 fsf 2
which resulted in some error and completely hung up the system. The
error looked something like as if the system tried to access the two
harddisks but couldn't and timed out repeatedly. We weren't able to do
anything and had to manually power cycle the system. Does anybody know
what the problem could be? Is there a way to avoid these lock ups and
get the system back to life? We are certain that termination is ok, the
scsi ids are: 0 and 10 for the harddisks and 6 for the tape.
Any help would be greatly appreciated,

^^^^^^^
This is the one (7*8+3=59=0x3b). Part of the southbridge - power management,
isn't it? I would think the error is quite harmless, the 2.2 kernels don't
support ACPI anyway.
