[ale] autoboot fail

[maltzen at mm.com (Gary Maltzen)]

(At least on x86) NTLDR only uses the ARC (s-d-r-p) path to boot NT; other
OS' are booted by simulating a load of their partition boot record as if the
partition had been marked active. For example, to boot linux off /dev/hda3
through NTLDR, I would

  1) dd if=/dev/hda3 of=bootsect.xxx bs=512 count=1
  2) copy bootsect.xxx to C:\
  3) add to C:\BOOT.INI the following line
      C:\bootsect.xxx="Linux (hda3)"

On a machine (IRIX 5.3) - there is a machine (not mine!) that won't boot.
It gives the following error.

"autoboot failed"  scsi(0) disk(1) rdisk(0) partition(0)/unix no such file
or directory

now, I can use a software install utility and CDROM to gain access to the
directory tree
and if find that /dev/dsk/dks0d1s0 is indeed mountable and I can swim around
in it
and I see that /unix does exist and seems to be unaltered (at least
recently).
SO if the kernal exists and it is on a mountable partition, why do we get
the
above error and what can I do to fix it?

Any tips as always greatly appreciated!


thanks
