"The HY57V561620C is a 268,435,456bit CMOS Synchronous DRAM, ideally suited
for the main memory applications which require
large memory density and high bandwidth. HY57V561620C is organized as 4banks
of 4,194,304x16."

That is directly from the datasheet I dug up on this chip. I was just
misreading it, thinking bytes when it said bits....oops.

How do hidden partitions work? Is it a hole in the filesystem? Is the FAT
later on in the drive? I don't get it...
