(Why not 7.10?!) Not only doesn't MS-DOS 6.22 support FAT32, it also doesn't support LBA. This means VERY bad things will happen if you try to access anything above 8G (7.8?) with MS-DOS 6.22! With that in mind, it should be safe to restrict MS-DOS 6.22 to partitions below this limit. To support anything above 8G (7.8?), you need both : 1. A BIOS that provides Extended Int $13 functions (ie. LBA support) AND 2. An O/S that knows how to use the above (aka. LBA support). You can add the first, if required, by installing Ontrack Disk Manager 9.X (there were OEM versions available for free from Seagate and the like, not sure if that's still available). This uses about 5K of your conventional memory, IIRC. There may be other drivers that add similar BIOS support, perhaps the EZ-BIOS you mention, not sure. As for the O/S, I'm not aware of anything that will provide the LBA support to MS-DOS 6.22. You can try instead : MS-DOS 7.XX (preferably 7.10, which adds FAT32) PC-DOS 7.10 (yes, it does exist - OEM only) Enhanced OpenDOS 7.01 (see http://drdosprojects.de/) FreeDOS 1.x ROMDOS 7.10 others (?) Of course, MS-DOS 7.10 is available as Windoze 95A through 98SE.
