But we have tricks to make it think it's on the 1st HD, and so it doesn't really
need to be there. Any modern BIOS can perform the trickery, but it's easier with
grub or lilo.

Shortly after you left. Warp 4 became MCP (merlin convenience pack) after FP15.
With MCP came LVM from WSeB. A bit later Serenity Systems released MCP as
eComStation 1.0, which is currently at 1.2. MCP became MCP2 at MCP FP level 2,
and is currently at FP level 4. IIRC, the eCS 1.2 was released at MCP FP level 3.

As long as IBM BM is installed, OS/2 can have its C: on any HD. OS/2 hasn't
required C: to be the boot drive in any version I've used, 2.0-up.

Great DOS apps are why I still run OS/2 24/7. Mebbe someday I can figure out
how to make them work as well on Linux. (without installing OS/2 in a VM. ;-) )

I just took the kids machine (no Linux), for which I had just cloned a HD
as a backup, and tested what is possible without grub or lilo:

Following is prepped to boot from OS/2 on /dev/hdc1 as C: (semi-normal
configuration, with both OS/2 & W98 primaries "hidden". normally
one or the other would be "visible".)
