Early versions of Win95 didn't support LBA or FAT32, I think corrected in OSR2 or so. Anyways, here's what the FreeDOS Wikipedia page says:

"FAT32 is fully supported, even booting from it. Depending on the BIOS used, as many as four LBA hard disks up to 128 GB, or even 2 TB in size are supported."
