I'd like to be able to obtain a unique system ID for computers. This
system ID should stay the same, but be unique.

I propose to read the MBR and boot sector of the hard drive, combine the
512 byte buffers together to make a 1024-byte buffer, and then do
something with that buffer. But what could I do?

Checksum?
First x bytes added to last y bytes?
Pick out ten bytes at position xxx?
