|To answer your first question. Boot into the BIOS and see what options are available for floppy drives. Do you know what capacity 5 1/4 drive you have. They came 360K or 1.2M. If those choices are available then you can use the drive on that computer. Also, if you want to mount permanently you would need a BIOS that allows TWO floppies, I would assume. |
That would be one 5 1/4 & one 3 1/2. The older computer will be more likely to have a floppy controller that can handle the 5 1/4 but if the WinXP computer has the options I would use that one and then just network any other computers you need to work with the 5 1/4 floppies.
If you share that drive you can access it from any computer on the network. No need to install to that particular machine.
In order to install both types of floppies you will need to have the correct type of power connectors available and also a floppy cable with both the connectors for 3 1/2 & 5 1/4 drives.
Going back to the type of 5 1/4 you have, it is most likey a 1.2M capable drive, which should read 360K, and if memory serves me 720K as well as the 1.2M.
Look at the link below for more info on the variations in 5 1/4 floppies.
As far as mounting internally, the drive should mount in any 5 1/4 drive bay which is the same size used for optical drives. Keep in mind the 5 1/4 needs to be mounted close to the 3 1/2 floppy drive because the same cable serves both.
