Juhani Krekelä 007af45879 Use `db` instead of `dw` for number of FATs 
Using `dw` ended up shifting all the values over by one byte, making DOS
think our 320K floppy was actually 16MiB in size, and had 46 sectors of
FAT instead of 1. This further lead it trash the setup stack and fail to
locate the disk directory.
