- You didn't say which IBM 70Mb ESDI disk, but it should have a little sticker
- on the front that says so. Below are the disktab entries IBM provides for
- all the 70Mb disks they made. If you're unfamiliar with disktab entries,
- ns=Number of sectors per track, nt=Number of tracks per cylinder,
- nc=Total number of cylinders on the disk, rm=Rotation speed, rpm. The
- rest are probably not useful to you.
