=46rom Ralf Brown's interrupt list error codes for disk I/O:

10h uncorrectable CRC or ECC error on read

The part about the primary volume descriptor is a bug in cdboot where the
read error message doesn't have a trailing \0, so it writes out both errors
on a read error. I'll fix that part, but your BIOS is claiming it got a
CRC error while trying to read /boot/loader in off the CD. If you mount
the CD under a running system can you read all of /boot/loader ok? (Maybe
compare md5 with a known good copy of /boot/loader.)
