I'm trying to install OS/2 Warp Version 4.0, and I find that it doesn't automatically partition the C drive, so... I boot up in DOS, and partition it from DOS. Next time I use the OS/2 disks, I don't get that error. Instead, I get an error saying that the CD Drive isn't ready. The light is on in the CD drive, but... I'm still getting this odd error. So, I reboot, and try installing OS/2 again. This time I go to the command prompt, to make sure that the CD drive can't be read from, and... I type in d:, and then dir, and I can read from the drive just fine! So why isn't the installer thinking I can read from the drive?
Anyways, after reading the manual that came with it, it says that if you have this problem, just install OS/2 off diskettes. The images to make the installation diskettes for OS/2 are on the CD itself, along with the program to make these. I didn't expect them to work with VPC, as per my other thread, imaging OS/2, but... I tried. I loaded the disk images themselves, off the CD, instead of using that program, and it worked! Until I got to a file, dpt20xx.add, on the fourth diskette. It couldn't read the file, and clicking on the Skip and Continue option that came up in the error dialog, I came right back to that file, and right back to the error. So... it would seem I'm stuck.
Also, while looking that file up online, I found a bunch of sites which seemed to suggest that that file was some osrt of CD driver - could the problem with the fact that OS/2 isn't detecting the CD, and this problem be connected?
Any help would be greatly appreciated!

I tried using some ThinkPad OS/2 Warp Version 4.0 updated installation disks, and am still not able to install OS/2. Here's the error I get, right when the install program should start reading from the CD Drive, asking me if I want to do "Easy" or "Advanced" installs:

ERROR: SYSINST2.EXE failed to return the target drive.

Reading at some of the comments on varrious newsgroups, I try going to the D:\OS2IMAGE\DISK_1 directory to try to run SYSINST2 there. There is no file sysinst2.exe. I go to D:\OS2IMAGE\DISK_2, and look, out of curriousity, and there it is! I try to run it without much luck, and
get this error:

SYS0191: D:\OS2IMAGE\DISK_2\SYSINST2.EXE cannot be run in an OS/2 session.

I've also asked for help, now, on comp.os.os2.misc.

Try accessing it in dos.

Did you update the boot disks ?
