Might be the size of the CF card - IIRC OS/2 Warp 4 doesn't like disks larger than around 2GB without updating the drivers on the installation floppies. Warp 3 may be similar, OS/2 2.x is smaller - somewhere around the 500MB mark I think. Also possible OS/2 doesn't like being installed on a logical partition.

Might be worth trying to install to a small primary partition at the start of the 2nd hdd and see if that works. I think OS/2 will also always see your DOS/Windows partition as drive 'C' and its own partition as something else due to it enumerating partitions in a similar way to DOS - first partition on the first drive gets drive C.

I have made os/2 partition 700mb (updated the original post to reflect it) and set drive f as installable and the boot manager is set to startable and the layout of drive stays the way I want to but when reboots to continue the install, it just show a blinking cursor and no os/2 name appear in top left but the boot manager sees it

If I move the os/2 partition to the start of second hdd and change it to primary, would that make it drive d as I would keep my drive d for games as dos and windows points there for them but will give a go, finger crossed it works

Even like OS/2 2.0 can install to a logical partition.

Having said that OS/2 is finkery. I think I would get DOS installed, then OS/2 then setup other partitions. You may also have a CHS/LBA issue, as well as size issues. I dont recall if OS/2 or what version supported LBA.

try both ways from davidrg and mR_Slug but unfortunately same thing after it reboots from installing the basic files to continue the installation and configuration - all that happens is blinking cursor - seem that os/2 doesn't like to booted from slave drive and can't seem see a way to even change the install directory where it wants to a single folder like dos or windows
