Hi Jerome,

let me summarize: You can fdisk, format and use 100 GB FAT32 LBA
partitions using a certain (which?) version of a non-8086, e.g.
386 optimized kernel of FreeDOS. However, doing the same on some
(which?) kernel which is trying to support 8086, you fail to use
FORMAT on said, probably FAT32 LBA, partition? I assume you did
use an 8086 kernel with FAT32 support compiled in? If not, you
should have gotten a warning from FDISK that FAT32 partitions
are not supported by that kernel.

What does the floppy (8086 compatible) edition kernel say at boot?

FAT16 or FAT32? LBA or CHS?

You need to be A LOT more specific about the context of the problem.
At least do mention the version numbers of kernel, fdisk and format!

PPS: Thanks for the mirroring!
