It is, but it would allow to boot off any scsi controller you put into such a box. Since quite some systems around have scsi only or in addition to IDE, this would be very nice to have.

I was playing around with ADLO on the K8, and I could get it to load grub, but grub hung right after loading stage2 every time. Video did not work at all. I'll give the builtin stuff a try.
