I'm using the latest snapshot (10/02/2001 iirc) and a custom kernel to
support scsi.

Here is the output of sgivol sd0 after another sgivol -i sd0:

Do you want to update volume (y/n)? y

I'm not sure if my partition settings in OSLoadPartition and SystemPartition
are correct. Here is the disklabel sd0 output:

I just figured out that my sd0a is corrupt.
I was running fsck and now test if the boot loader and sd0a make trouble:
Extracting the sgiboot bootloader and using diff it shows that there are
differences between the installed loader and the loader on the disk.
Maybe my disk setup is wrong so there are overlapping areas overwriting
each other.

Do I need to reserve any special diskspace for the boot loader or is my
setup shown above usable ?

Thanks a lot, Hendrik
