Cannot set an installable partition with FDISK
Last Updated: 3rd July, 1997
When Advanced Installation is chosen for the installation of Warp, FDISK
thinks that "your partition mapping may be corrupt". Partitions
can only be deleted but this won't help. As a result, you can only use
Easy Installation and choose the default partition. This may not be what
Partitions on your harddisk (for example Linux' ext2fs) may be misaligned
so that it confuses FDISK. This is probably a bug in Warp.
A related (but different) problem might be that you are using a harddisk
which is bigger than 4.3 Gb. In that case, you might want to use IBM's
(E)IDE drivers from the OS/2 Device Driver Pak On-Line.
The FDISK included with OS/2 2.1 (or Warp Beta II) does not have this problem.
You can download it from here.
There are at least four possible solutions to this problem.
If you have the floppy version of Warp, backup the disk containing FDISK
(Diskette 1). Copy the FDISK of 2.1 onto that disk, replacing Warp's
If you have the CD version of Warp, one solution is to make the diskimages
from the CD. Execute MAKEDSKS.BAT or MAKEDSKS.CMD on your CD for that.
Then proceed as described above. If you're not an expert, this is the way
to go. The disadvantage is that you'll need lots of floppies, and installation
will take quite some time. If I were you, I would not install all bells
and whistles. Once you have a minimal Warp system on your harddisk, you
can install other parts directly from the CD. When Selective Install asks
for a path (defaults to A:), change that to x:\OS2IMAGE, where
is the drive letter of your CD-ROM.
If you have the CD version, you could also temporarily copy all the installation
files to your harddisk, if you have the diskspace to spare (about 45 Mb).
See these instructions for more information on
how to do that. Then copy the 2.1 FDISK over the Warp FDISK (in D:\OS2IMAGE\DISK_1)
and install from there. After the installation, these files can be deleted.
Probably the easiest solution is the following approach. This one worked
Get the good FDISK.COM from OS/2 2.1. Copy it to
a seperate, empty disk.
Boot from the Warp disks. When you get to the blue installation screen
(Diskette 1) where you have to choose Easy or Advanced Installation,
press F3 for the command line.
Type A: to go to the A: drive.
Insert the disk with the good FDISK.COM and start it. You get the standard
warning screen, "FDISK can be dangerous" etc.
(Re)partition your harddisk to your likings.
Write down the drive letter where you want to install Warp (say X:)
Edit (e.g. under DOS) the CONFIG.SYS on Warp's bootdisk 1 and insert:
Boot from the Warp disks. This time, Warp will not load the faulty
FDISK.COM and it will not ask where you want it to be installed. It will
install on X: without further asking, so be sure you got the drive letter
In the end, I borrowed a SCSI tapestreamer, backed up my data and repartitioned
the whole disk. FDISK and my harddisk are buddies again...
