using /dev/sdb is ok - your palo command looks "right" to me.

This looks like palo loading the vmlinux.

Sounds like ASP support may be broken.
The way to find out where IOAQ and GR2 registers are pointing.
They should point to functions in System.map.

to the disk drive. The boot drive is expected to spin up on it's own.
I don't know if newer PDC does send START_UNIT either...
