Turbo XT BIOS, Floppy Drives, and MS-DOS 3.3 and Later (77707)

The information in this article applies to:
    Microsoft MS-DOS operating system 5.0

This article was previously published under Q77707


On machines with a Turbo XT BIOS dated 1980, floppy drives may be unusable under MS-DOS versions 3.3 and later because the BIOS does not indicate the floppy drive model type properly. In some earlier versions of MS-DOS, the model type check is performed incorrectly, so the drives are usable.
