Allow pc86 bootloader to boot from more floppy drives.

When the bootloader probes the drive geometry, the BIOS can clobber the
es register.  If this happens, the bootloader loads the program to the
wrong address, and jumps off the code.  This happens with an emulated
floppy drive in Bochs or QEMU, but not with an emulated hard disk.
