mine's a combo drive, (hence relatively recent and you'd have thought it

as best I can tell, for whatever reason, the kernel's drivers seem to corrupt
stuff from ide from some unknown reason... On mine, since it's got problems
with the cd drive, when I start the install process, when it loads the
ramdisc from cd, the ramdisc image must be corrupted, so it can't mount it &
hence bombs out :/

in my /var/log/syslog I get things like:
Mar 7 01:06:09 sn693 rawdevices: failed
Mar 7 01:06:18 sn693 kernel: hdb: dma_intr: status=0x71 { DriveReady
DeviceFault SeekComplete Error }
Mar 7 01:06:18 sn693 kernel: hdb: dma_intr: error=0x10 { SectorIdNotFound },
LBAsect=79215, sector=79152
Mar 7 01:06:18 sn693 kernel: hda: DMA disabled
Mar 7 01:06:18 sn693 kernel: hdb: DMA disabled
Mar 7 01:06:18 sn693 kernel: ide0: reset: success
kinda worrying, especially for a board that's supposedly tested by mandrake
itself...... I'm guessing your box/hd's has problems messing with the dma
hence the lockups...

in /etc/lilo find a section similar to this:
image=/boot/vmlinuz-smp
label=linux-smp
root=/dev/hdb1
initrd=/boot/initrd-smp.img
append="devfs=mount hdc=ide-scsi mem=nopentium"
vga=791
read-only
change the append line to something like this
append="devfs=mount hdc=ide-scsi mem=nopentium ide=nodma"
mem=nopentium is useful on dual amd boards if you plan to use opengl agp
cards otherwise don't worry about it - the hdc= bit is so I can use the cdr -
you'll have something similar for yours
make sure you've installed hdparm & drivetweak-kde - drivetweak-kde will then
let you play with the ide settings to your heart's content :)

asus has just come out with one relativly recently - I don't know what's it's
like, or how stable, but it'll be based on the same chipset and may suffer
from the same problems as the tyan. The tiger is a relatively stable board,
and because it's been around for longer, it's usually easier to find out info
about some of it's problems/issues ;)
I've also read in a couple of places that the redhat 7.2 kernel seems to
handle better with dual amd tyan boards (thunder/tiger) - if you're out to
use the board as a server, it might be worth considering until mdk becomes a
little more stable :) (sorry guys - I'm a big fan of mandrake as is everyone
else here, but it's def got some issues with some people's tyan boards...)
Ofcourse, it could be nothing to do with the ide/dma and all of this could be
wrong, it's just a got feeling... :)
