|Nice find Leroi !|
How old ? I'm 60 myself.
Your problem is rather rare.
If the bios Setup of the computer was seeing the floppy drive as B.....
- if it's a desktop computer,
- a single floppy drive must be connected to the END connector on a 3 connector floppy data cable, not the middle one, to be seen as assigned A
- some old floppy drives have jumpers that can be set so the computer sees the drive as assigned A or B - usually you do not mess with those - they're set to A by default, when the drive is connected to the END connector on a 3 connector floppy data cable.
- in rare cases, the floppy data cable may have only two connectors, and in that case, there must be wires that switch positions in the connectors between the two ends of the data cable for the floppy drive to be seen as A - the cable has a group of some wires in part of the ribbon cable that twist 180 degrees - flip positions.
NOTE that data cables for really old MFM or RLL hard drives have the same connectors and numbers of wires as floppy data cables, but the wires DO NOT change positions between the two connectors on the ends of the cable - a floppy drive will be assigned B by the bios if you use that cable.
OR - relatively rare - if the data cable for an old MFM or RLL drive has 3 connectors, there are wires that switch positions between the two for the drives, but the wires that are flipped are different from the wires that are flipped for a floppy data cable - a floppy drive cannot work on the end connector - it wil work on the middle connector but it will be assigned B by the bios.
- if it's a desktop computer, or an older laptop computer that has a conventional (built in, or a swapple floppy drive module in a bay) floppy drive
- many bioses have a setting that can swap the drive letter assignment for the single floppy drive. That's set by default so that a floppy drive attached to the END connector on a 3 connector floppy data cable is assigned A, but that can be set so it assigns B. If you're not sure whther than setting is assigning B, load bios defaults, save setiings
Software may be able to change that setting in the bios without you having to do that yourself.
