[RndTbl] Linux 4K drive formatting

Sat Jan 19 18:47:19 CST 2013

 Oh, one more thing.  The cylinders/heads/sectors legacy stuff is
irrelevant today.  Even the old (4-entry) partition table also had a pair
of fields for starting position (displacement from sector 0) and size of
partition, and on later PC's, these two parameters alone were used during
boot and then for the booted OS to know where the partitions are.  By the
time we got LBA (large/logical block addressing), this practise was already
the case.
