When I change things like the no. of FAT's or the start of the first FAT
sector, in this table on my hard disk and/or on floppies, my MSDOS 3.3
does not acknowledge this and does not use the new offsets and sizes.
Does MSDOS 3.3 use some other ways to determine these parameters?
(Well, it actually shouldn't, but apparently it does :-)
Can anyone shed some light onto this matter?

I've never been able to get just one fat to work, and I've seen several references to the fact that the two fats are pretty-well wired into MS-DOS. As for the start of the fat, that's controlled by the the number of hidden sectors (the partition track) and the number of reserved sectors (usually =1, the BOOT sector). I have no idea if you can have more than one reserved sector (even though it's specifiable in the BOOT sector).
