I have a 33Mc MB with AMI Bios. One of the options under eXtended CMOS
setup lets me set a "scratch RAM" option. The manual says the following:

"Scratch RAM Option lets you choose from (1) saving the user definable
drive type 47, or (2) use the stack area in the BIOS to support programs
like OS/2 ...."
Chosing option 2 reduces available base memory by 1Kb. Option 1 uses 100
bytes of the BIOS stack area (no reduction in base memory).

Might it be that Phoenix implements 'option 2' to support OS/2 by default?

Hope this puts you on the right track.
