I dont know what exactly was the problem, but it is now fixed for me. Anyway, thanks to the magic voodoo that helped me :-)
Here are the relevant commands I used between reboots. vim /etc/modules # added piix near the top depmod -a aptitude install yaird depmod -a dpkg-reconfigure linux-image-2.6.15-1-686 # didnt select yaird # complained about /dev/root which is "not a directory". Indeed: # ls -l /dev/root shows a block device. But I was in single user mode. So init 2 vim /etc/lilo.conf # check what happend : no idea. Changed default image lilo -t lilo And here is relevent part of dmesg, which shows that ICH4 is now used earlier in the boot process, leading to correct DMA settings :-) Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ...
