I'm willing to bet this is a motherboard/BIOS issue. My old 32 bit desktop has a half height combo 3.5"/5.25" floppy drive. It was originally seen as drives A: and B:, and which was seen as which was controlled by a jumper setting on the drive. That went away in an emergency motherboard replacement. The new mobo would see only *one* of the drives as A:, and I had to pull the drive and change the jumper setting if I wanted to access the 5.25" drive instead of the 3.5" drive. The new machine doesn't have floppy slots on the mobo, so while I have the drive I can't hook it up. I *do* have a USB 3.5" floppy drive which is seen as A: when connected and works fine, but I have no current way to access 5.25" diskettes. (I have some old stuff I'd *like* to access) (For that matter, I still have my original XT clone on a shelf, with two 20*MB* Seagate MFM hard drives where the drives do not have onboard controllers and connect to a card on the mobo. I'd *love* the get the contents of the drives copied to a USB flash drive, but haven't found a way to do it.) > Zbigniew ______ Dennis _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
