I'm a novice at PC's and have the following situation. Any help will be greatly appreciated. Goal: To get a 3.5" floppy disk drive on a old (4+ years) IBM PC/XT (preferably with high density). Situation: I bought a 1.44 Meg floppy disk drive from CompuAdd I bought a disk controller that says it can control both a 5.25" and 3.5" 1.44Meg floppy disk drive. I have DOS 3.0 (sorry). I have a 3.5" drive on a Sun Sparcstation, with some dos tools for reading and writing. I would like to use it to transfer work back and forth from home and work (mostly editing documents). Symptoms: 1) The system will no longer boot from the hard disk. - I have a valid SYSTEM on the hard disk. - It will only boot if I have the DOS disk in the 5.25" drive 2) When I format the 3.5" drive, it formats it to 1.2Meg (not what I expected, I expected 1.44 because I set the jumpers that way on the controller). 3) I can access all the disks on the machine. Questions: a) What are the complete set of things I need to do to the mother board to inform it of the other disk drive? b) What else do I need to do to the system so that it will begin booting from the hard disk again? c) Do I need to upgrade my version of DOS so it can recognize a 3.5" drive? d) What are the other relevant questions I am not asking, and what are the answers. Rumours: 1) The older IBM PC/XT's cannot support a high density disk. 2) I want the 7 switch off, and the 8 switch on, for the switches on the mother board. 3) I need a new version of DOS to do this.
