    Harry,
    I misunderstood, I thought you had a grub mbr on a floppy (have you tried
    that? i never have) and that worked to launch grub, then the os.

    When it fails at stage 1.5, that is between the mbr & the kernel, I beleive
    that is when it reads grub.conf.
    So when it fails, would that mean it it fails starting or ending 1.5. Could
    that mean it can't access grub.conf?

    I just noticed that your earlier post (first?) shows:
    kernel /vmlinuz-2.4.20-28.9 ro root=/dev/md0 hdc=ide-scsi vga=791
    I don't know if it could matter but vga=791 is invalid, you probably want
    vga=792

    When you boot with the floppy or cdrom, do you get a raid system?
    If not, then you may still need to compile a kernel with raid support. If it
    failed at that point it would probably display a kernel panic not just a hang
    at stage 1.5.

    just some thoughts.
