IBM PC-DOS 2000 vs DR-DOS and FreeDos

Doesn't really matter, which of the DOS versions you use. I don't know about IBM PC-DOS 2000, but DR-DOS and FreeDOS will work for you. I extracted the DOS Version from the Windows 98se and use it for such things.

I suspect it is the bios. Two basic ways to get around it exist. One is a supported bios the other is an overlay program. As you say though dox 6 and win 3 won't support them anyway. Pretty sure freedos has that fixed. I doubt IBM's dos fixed it. http://www.wdc.com/en/library/legac... Nothing wrong with partitions. Playing to the angels Les Paul (1915-2009)

I think you are going to have the same problem with all all 16 bit DOS versions as the maximum volume size is 2 GBs, a huge size when MS-DOS 6.22 was current. You could get more using a third party formatting system that would use cluster greater than 32 kBs 8.4 Gbs seems more like a BIOS limitation which no amount of software is going to overcome. Stuart

I think Ghost 2003 uses DR DOS and can handle drives of any kind. DR DOS is not free.

Another option would be to SYS the drive with a 98 bootdisk and then copy the contents of the windows\command folder on a 98 drive into a dos folder on the 20 gig. You'd need to add a few other files but it'a fairly easy walk-through. That's after you settle the 8.4 gig issue. It is, as already mentioned, a bios limitation. Besides an overlay you could also install an ATA add-on card. You could probably find a cheap ATA66 card on ebay. Check here for fat32 compatible dos: http://en.wikipedia.org/wiki/Compar...
