}Now this one makes sense.  Except that BIOS does not limit you to 1024
}cylinders, that is DOS.  So theoretically you could have 2048 x 64 x 63.

Sorry, but that is indeed a BIOS limit, since the BIOS only uses ten bits
to specify the cylinder (there are a couple of BIOSes which use twelve
bits, but they aren't "standard").  DOS is simply using the standard BIOS
interface--you could always write a device driver that knows about the
two nonstandard cylinder bits if you have such a BIOS.
