I just tried pfdisk after I booted DOS off a diskette, and after I booted from the hard disk. They both gave the same result. If they didn't, I have further clue. Let me reiterate, that I had originally had DOS occupying one slice which was the entire disk. I then attempted to install FreeBSD. I used FreeBSD fdisk and disklabel utilities to partition the drive into two slices. I did NOT reinstall DOS on the first slice. My question was whether I needed to reinstall DOS on the first slice. Has anyone very repartitioned their disk to install FreeBSD? If so, did you have to reinstall DOS? I guess I will now go back and reinstall DOS and see if the DOS DIR will give the correct amount of free space.
