P4P800-VM ICH5 and DVD-drive problem *SOLVED*!

[Kaj Wiik <kaj.wiik@iki.fi>]

Dear all,

To save others doing this trial-and-error loop, I decided to share my
solution..

I had a multitude of different problems that were changing with kernel
version and BIOS setup I am too lazy to list them all here..

My hardware:

ASUS P4P800-VM, AMI bios
250 GB SATA disk
NEC DVD-/+RW 2510
160 GB PATA disk
PATA disk and DVD are sharing one UDMA cable

Kernel version 2.6.8-1

The key was a correct (?) BIOS setup:
IDE configuration->Onboard IDE operate mode [Enhanced Mode]
Enhanced mode support on [S-ATA]

Grub kernel line:
kernel       /boot/vmlinuz-2.6.8-1-686 root=/dev/sda1 ro
(so hdc -> sda)

After this the DVD is at hda, PATA disk at hdb, and the SATA disk at hdc
(might be also in sda..).

I did not get the UDF writing working, the reason of my upgrade, sigh. I
do not know if it is related to the SATA problems..

Good luck,

Kaj
