The "magic match failed" message is issued by the kernel when it tries
|
|
to mount a file system and cannot find the correct header information
|
|
for that file system on the block device.
|
|
|
|
When Linux mounts the root partition, it tries to look for all the
|
|
different possible file system types on the partition in the order
|
|
minix, extfs, dosfs. It does this by trying to mount the different
|
|
types in that order, until one of the mounts succeeds. The messages
|
|
you describe means that linux has mounted a DOS filing system as root
|
|
--- the two magic match failures mean that linux has failed to find a
|
|
minix or an extfs file system, and the rest of the blurb is the
|
|
standard information printed out whenever linux mounts a dos file
|
|
system.
|
|
|
|
I'm not familiar with SLS --- I started out with mcc-interim --- but I
|
|
suspect that your rawritten disk should NOT have a dos file system on
|
|
it; mounting a dos file system as root is legal, but probably not what
|
|
was intended. Rawrite should be able to create a valid minix disk,
|
|
completely overwriting the dos information formatted onto it by the
|
|
dos format command. Your best bet might be to download the a2 disk
|
|
again. Then again, I might be talking garbage... Your mileage may
|
|
vary.
|
|
|
|
Good luck anyway - Who said Linux was the best thing since sliced
|
|
bread? Sliced bread doesn't even come close!
