try enablign scsi emulation support by :
+ compiling a kernel with scsi support
+ or trying
(i am not sure the module is called "scsi")
this will create sg device.
After that you need to append the parameter device=ide-scsi in lilo or grub configuration.
example :
Code:
...
kernel /vmlinuz-2.6.10 ro root=/dev/hda6 hdc=ide-scsi
...
