Since that, I have a problem reading my 3 1.2 diskettes. It This has nothing to do with the DOS VERSION. Some BIOS would like to see a 1.2M as drive A. Aside from that, the Disk_Change signal on your 1.44M may not be passing on the info to the system. If you: read a diskette, and change to another drive, then come back and read a second diskette, the problem would not show up. Read your manual(assuming you got one) on the 1.44M drive, see if there isn't a jumper you need to configure. Good luck, and have a great day.
