Knoppix 5.1

Mother board ASUS P5K with genuine Intel Dual Core 6750
2 (two) hard disks 160Gb SATA2
1 DVD
1 DVD writer
2 Gb memory

First disk that is recognized is hde. I fail to find my main disks
disk contains partitions for Windows and SUSE10.3. MBR has a grub bootloader, but does it matters?

On two other machines KNoppix just works fine.

I checked that the partitions are intact (Partion Magic under Windows); also SUSE runs OK. Please advise as why my hard disks are not found. I tried to parse through the log, I find no hda, no hdb.
