Log:
MFC: revision 200407
Cleanups the boot2 for pc98. There is no functional change.
- Make setting machine type and getting geom conditional for future.
- Remove unused RAWBOOT and CDBOOT supports.
- Remove unneeded include.
- Fix warnings.
This change is directly merged into stable/6 because stable/[78] have
new boot2.
