While the BIOS call supports 48-bit LBA, the MBR partition table is

Excellent point, but doesn't that mean a BIOS that supports LBA (which
as been around for many years) will support 2^18 TB? I think my
arithmetic is correct, but please correct me if I misunderstand.
Assuming a 512-byte sector size, the total number of bytes is 2^9 *
2^48 = 2^57 = 2^27 TB.
