I didn't post the original message, this is just a point of reference. Some machines (earlier ones) didn't have that option in their BIOS. Ah the good old days, when floppies were all we had! ( ;-+ )Which brings me to the.... ObHack: I have a number of 6809 OS9 Level I systems which I wanted to get working, well I had a number of drives I could use so I gathered them up and finally got 2 360's (5 1/4), a 720 (5 1/4), and a 720 (3 1/2). While writing the device descriptor, I found that the 3 1/2 could handle 100 ms access. Problem was the 1771 didn't support 5 1/4's or 3 1/2's at 100 ms. But the 8" drive would so I lied and told the OS that the 3 1/2 was an 8" drive. The only problem discovered was that it wouldn't format if the OS thought it was an 8" I then just loaded a device descriptor that told the OS that the 3 1/2 was a 3 1/2 but was under another name. I could now read/write/format the drive as I needed. Hey anyone out ever multiplex the drives to get 16 on a cable? Neil Cherry
