You can make your own:
Pretend a sector is 512 bytes.
Use the maximum number of cylinders of either 65535 or 1024
Use the maximum number of sectors up to 255
Use the maxumum number of heads up to 255
Try the above with 1024 cylinders first. If it doesn't fit, use
65535. That's all the BIOS does. It's just used to fit the
stuff into registers for 16-bit BIOS calls (see int 0x13).
Actually, different bioses do it in different ways, that is just one way
( and possibly the most popular ). The same bios can even do it
differently depending on what options are selected in the bios setup.
Of course, this only effects Microsoft operating systems because
everyone else is sane and supports LBA.
