[Freedos-user] Is there a maximum partition size in the FreeDOS kernel?

[k***@comcast.net]

Good day:

Trying to do a DIR on an NTFS partition, one of my friends is getting
the following error:

Divide error, stack:
FB3C 158E 0246 0000 14CB 38C8 6AE5 158E 7939 0000 0000 0000 38A4

What's the size limit on a partition for the FreeDOS kernel? I believe
this was a 160GByte partition, but I'm checking to be sure. I don't
have anything that big to test with!

The large size seems like the first place to look.

Thanks again for the great support.

Mark

2 Gb for FAT16 partition, 2 Tb for the FAT32 partition. But all
programs, which use only 32-bit arithmetics and use plain old DOS functions
(non-FAT32 aware) always will see "2 Gb free", even if there (on FAT32
partition) is more free space.

In crashing this machine I found that the extended is limited to 8gig
out of which you can carve up your logical partitions which share the
2gig limit.

If BIOS doesn't present INT13 extension functions - then yes, FreeDOS
limited to 7.8 Gb. If those functions present in BIOS - then FreeDOS may
access all disk space.

Again: 2 Gb is a _FAT16_ limit. FAT32 limited to 2 _Tb_.

Legacy windows / PCdos2000 is what I have for a legacy app of two.
Tricky but do-able since I started with Suse 7.0 and kept copies of
fstab .
