• Windows 98 was the last to use dos 7, Windows Mellenium Edition used Microsoft DOS 8 (Only came bundled in windows setup)

Maximum Drive size support under DOS 6.22:

               FAT16 tops at 2GB for DOS 6.22. DOS 6.0 tops out FAT16 at 528MB, IIRC.

Your system indeed will probably top out at 8GB for drive recognition, but it could do 32GB, depending upon whether or not you've got the latest bios for your system. If it's a 440FX chipset based system, odds are that the latest bios will only get you 8GB. 440LX and later will probably get you 32GB max drive size without a drive overlay program.

NT4's FAT16 max partition is 4GB, IIRC. I could be wrong on that.

Try to ID the motherboard and do a bios update in any case, if the system board doesn't recognize your drive properly.
