I'm not familiar with this version of the Phoenix AT BIOS, since the generic
version right now is 3.10, not 1.X. However, the SETUP routine customarily does
not allow editing the "coprocessor" field. When you run the program it checks
your motherboard switch settings and then looks for the presence of a math chip.
If it finds a chip and a proper switch setting, it will acknowledge the
presence of the coprocessor.

Does your motherboard have DIP switches? If yes .. is the coprocessor switch
enabled?

On most Phoenix BIOS sets having SETUP in ROM, you can enter the setup
program with CTRL-ALT-ESC.
