Ed,

FWIW, I got this back:

The new .PIF doesn't seems to work with FP extended (it works with Non-extended) without the MEMLIMIT command but the MEMLIMIT command is working great.

>Yes - you need to create a .PIF for the FPDOS executable and explicitly limit the amount of DPMI/XMS allocated, and do not give any EMS memory in the memory tab of the property sheet.
