The 945G has two "secret" sets of BIOS commands.
The first must be turned on from within the BIOS under AMT functions which
then (following are reboot) allow you to program this motherboard as a
workstation under hard server control. Accessed by pressing CTRL-P.
The second command is indeed CTRL-F1, but that is only available on the
chipset 945GM-S2 which is not the case here.
This computer is limited to 4GB which does not meet the requirement for
memory remapping, so the function is not available.
