Hello,

here some personel observations. Maybe they are result of little 
experience of mine. Maybe they are of use for others.

I use rev11 of it/ite8212 Dual Channel ATA RAID controller. On each 
master there is a 80GB harddisk.

When I set in the bios RAID 1 there comes an message similar
INVALID GEOMETRY: 0 PHYSICAL HEADS?
and booting stops.

When I set NORMAL, I get IRQ-timeouts for both disks. (IRQ 10)

but booting continous and I can use the disks.

hdparm => 15.70 MB/sec
