I recently picked up a boxed edition of OS/2 2.11 on 3.5" disks. This is the fairly rare OS/2 2.11 which is essentially OS/2 2.1 with Fixpaks, I don't believe it's the other OS/2 2.11 (i.e. the SMP version).
I also have OS/2 2.1 on CD-ROM and since the CD-ROM really just contains the contents of each floppy disk in appropriately named folders I was convinced that I should be able to find a way to turn my OS/2 2.11 floppy disk version into one that I could install from CD instead.
Moreover I naturally wanted to use a regular ATAPI/IDE CD-ROM drive, and of course I wanted large hard drive support as well.
So by slipstreaming the official IBM updated IDE and ATAPI drivers and by making lots of mistakes along the way, I actually managed to get it to work!
That is:
- I created a CD-ROM containing the contents of each floppy disk, the printer drivers, the display drivers and MMPM.
- I created a modified Diskette 1 which supports large hard drives and ATAPI/IDE CD-ROM drives.
- I modified the config.sys on my modified Diskette 1 to actually use the CD-ROM rather than floppy disks for Diskette 2 onwards.
It was one of those things that probably took me an awful lot longer to accomplish than any time that I actually saved by being able to install from CD instead of from floppy disk! Nevertheless I was pleased to get it working, and it's given me a much better understanding of OS/2's installation and boot process.
I took plenty of notes along the way but they're only in Notepad and they could probably do with a little tidying-up before being posted for anyone else to follow. And whilst I did all this with OS/2 2.11 I expect the same steps would work to convert a regular OS/2 2.1 floppy disk edition into a CD-ROM installable version.
Would anyone be interested in a write-up of this process, or would this be useful for the Wiki at all?
Richard.
