I have received a used IBM PC with a 40 meg Tulin hard disk and a DTC controller. Unfortunately, the system believes that it has a 10 Meg disk. The system is now running Venix. FDISK tells me that I have a 10 Meg disk. I would appreciate knowing how to tell the system that the disk is really a 40 Meg disk? (A diagnostic program that came with the system scanned the disk and verified the size). Thanks for any assistance.

Last time I installed a drive, it was a 72Mb drive by Micropolis. One of the procedures you had to do was run the IBM diagnostic program (this was an AT, but I expect a PC has a similar procedure) and tell it what "type" of drive you had. It's a number, usually 1-6 I think. The number is stamped on IBM disks -- with ours, the documentation told you what to set. I think that the diagnostics program informs the drive controller what to make of the drive. If the PC doesn't have something like this in its diagnostics, check the drive controller documentation and it probably will fill you in. It may be a dip switch setting. Actually, if the drive installation documentation didn't tell you how to do this, you should complain. -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% - Jim Frost * The Madd Hacker - UUCP: ..!harvard!bu-cs!bucsb!madd | ARPANET: madd@bucsb.bu.edu CSNET: madd%bucsb@bu-cs | BITNET: cscc71c@bostonu -------------------------------+---+------------------------------------ "Oh beer, oh beer." -- Me | [=(BEER) <- Bud the Beer (cheers!)
