What the Solaris 10 boot-blocks do (which is different in
OpenSolaris/Nevada, and somewhat varies between updates of Solaris 10) is:
- create /packages/ufs-file-system (or hsfs-file-system)
- call do-boot, which it has just defined.
At the point above, where it has failed and you are at the ok prompt,
you should be able to see do-boot, which includes something like:
loadbase " hsfsboot" get-file if
." Boot load failed" cr xit
It's pretty clear you are dying in get-file, which is also external at
this point, and you can debug it.
The "seek failed" message comes from an attempt to read a block that
isn't within the partition boundaries. Either there is something wrong
with the HBA driver for the cdrom, or something is going wrong chasing
down hsfs data pointers.
