- *	ld -N -T 7c00 asbootblk.o
- *
- * This should result in a file with 512 bytes of text and no initialized 
- * data.  Strip the 32 bit header and place in block 0.
- *
- * When run, this program copies at least the first 8 blocks of SCSI
- * target 0 to the address specified by RELOC, then jumps to the
- * address RELOC+1024 (skipping the boot block and disk label).  Usually,
- * disks have 512 bytes per block, but I don't think they ever have
- * less, and it wont hurt if they are bigger, as long as RELOC + 8*SIZE
- * is less than 0xa0000.
- *
- * This bootblock does not support fdisk partitions, and can only be used
- * as the master boot block.
