Log message:
Clamp BIOS io attempts to < 2 ^28 - 1 sectors (a.k.a. 128GB for
512-byte sectors) as some BIOSen get confused when we ask for sectors
higher up.
Uss u_int throughout the boot code to calculate sector addresses,
since 32 bits is enough to do 28 ^ 1 - 1 arithmetic. Add checks
for wraparound.
I can now install and boot from the 7th extended partition below
128GB.
Much feedback & guidance from deraadt@. Also from weingart@ on
BIOS io.
ok deraadt@ (less a couple of minor tweaks found in testing)
