I've been trying to install OS/2 1.2 EE over AIX on a PS/2 and I encountered a problem. The problem is that I could not remove the old AIX partitions on the hard disk. I was able to install OS/2 over the DOS partition but 70% of the disk was still allocated for AIX. I finally "solved" my problem by installing AIX and aborting the installation at the point where AIX starts to prepare the disk. This left me with one partition of 1 cylinder and the rest unused. My question is this, is there a way to remove partitions of other operating systems using only the OS/2 software provided? James W.

You should be able to boot from a system floppy, then use the FDISK command.

Someone else has already suggested booting off a floppy and using FDISK. It is by no means clear that this will work for foreign (i.e. non-OS/2 partitions). The OS/2 FDISK that I have claims to understand only OS/2, DOS and Xenix partitions. I do not have a PS/2 with AIX installed on it, so I have no way of proving or disproving my theory. The only way that I have found to *reliably* recover an entire hard disk on a PS/2 is to use the low-level format. To do this, boot your machine from the reference diskette; when the first menu appears, do a <control>A and you will get the "Advanced" ("Alternative"?) diagnostics menu, which includes a low-level format. Using the low-level format (which can take a l-o-n-g time for a large disk) returns you a virgin volume. The OS/2 installation will then force you to partition, and offer you the entire volume. Of course, this approach is no use if you have stuff in other partitions on the volume that you wish to keep.

The only parameter that I know of is /d to delete the current partition. I haven't found any documentation on any other parameters. I tried booting from a DOS disk and using its FDISK but it will only delete DOS partitions. When I installed OS/2 in the one paritition that was available I was able to run the FDISKPM program. Unfortunately this program would only let me make the non DOS/OS2 partitions startable, it wouldn't let me delete them. James W.

If the disk partition is not marked as a DOS/OS2 partition then it will not get deleted by FDISK. When I installed OS/2, I had already had UNIX on the machine. Just for kicks, to sterlize the file system, I typed in rm -r / This did, in fact, kill the filesystem and the UNIX fdisk along with it; I couldn't delete my 200MB UNIX partition. I didn't want to destroy the two DOS partitions on the disk by doing a low-level format (which was the only way I could see of removing those partitions) so I used NU (Norton Utility) to change the partition ID byte and made it a DOS partition. I was then able to delete it and continue on. Cheers!

Startup in maintanence mode: NU /m choose absolute sector under selections and choose sector 0, track 0, head 0 Blank out the data for the foriegn partition. Save the sector (ESC then W for write). Reboot. You should no longer have the foriegn partion, so run FDISK. Voila. Robert Kelley Cook University of Notre Dame
