Odd.  The problems you were seeing are to do with the BIOS level
stuff, which is really independent of what OS you're trying to boot
up.  At a guess you actually did something a bit differently during
the install.

For future reference, one thing that has changed over time is using
'packet' mode (BIOS Int 0x13 extensions) -- this provides an
alternative to CHS (Cylinder Head Sector) addressing as used in older
BIOSes.  Packet mode is appropriate for large disks, and allows you to
boot from cylinders higher than 1023.  It's basically the norm on any
recent system with large disk drives.  Problem is you need a BIOS with
specific support for packet mode or it just won't work, so the default
has always been to assume 'nopacket'.  It has been mooted that
switching the default to packet mode is an idea whose time has come,
but that change wasn't made between 4.x and 5.x.  See boot0cfg(8) for
details of how to switch modes, but generally it's:

    # boot0cfg -o packet ad0

        Cheers,

        Matthew
