Yes, and they are in DOSEMU too, but ...

indeed. But we don't know what the original poster did exactly.

That's true. The maximum that the MFS (int2f/110c) reports is now:
32 sectors/cluster
1024 bytes/sector
65535 total clusters
65535 free clusters

so 2G max. A similar limit exists for int21/ah=36, and although you can
stretch that many DOS programs would be confused if you would do that.

The only way to get around that problem is to find a way to communicate
between the MFS and int21/ax=7303. That is certainly possible for
FreeDOS, but I'm not sure about Win98 DOS. Only a few DOS programs know
about that function.
