The original FAT system was restricted to about 32MB.


Not so!
DOS 1.0 supported single-sided 8 sector/track diskettes (160KB)
DOS 1.1 supported double-sided 9 sectors/track diskettes (360KB)
DOS 2.0 supported 10MB hard disks and subdirectories (PC-XT)

Actually, DOS 2 supportted much more thn that - it was restricted to 64k
SECTORS IIRC. 8Mbytes per partition? on 512 bytes per sector - summat
like that

I spent 3 dull months writing a BIOS patch to an RM machine to utilise a
80Mbyte drive, by chunking up pyhsical 512byte sectors into 2K logical
ones....

DOS 3.0 supported FAT-16 and 32MB partitions (PC-AT)

There was also the choice of CP/M for the original IBM PC - can't remember
what filesystem that supported.

Sadly, I was there ...
