        src/sys/arch/i386/stand/bootxx: pbr.S

Log Message:
Some systems (esp. those with a Promise IDE controller card) seem to
destroy %dl (drive number) across the 'disk reset' command.
Preserve %dl across that call and all registers across the disk reads.
Reorder the code to remove some long conditional jumps to save space.
