Have you tried installing Win98SE on a drive of that size and partitioning as 2 partitions, formatted as FAT32? Speaking from experience, I know the Keystrokes Point-ofSale software, which is DOS based, works just fine inside of Win98SE from a DOS window and can access partitions of the size you describe. And yes, you can still access serial and parallel devices(such as receipt printers) the same as you would from DOS 6.22 🙂
