Install Win2K Pro as Std PC, non ACPI

I have a Video Editing card which requires that the Win2000 Professional be installed as a Standard PC, not a ACPI PC. But during install, i do not get any option to do this. I am only able to change it once the Install is complete. This means that W2k has already done all IRQ/Mem Addr assigments which i now cannot change. Bios does not allow disabling of ACPI fn. MBD is Intel 850MV. Any solution?
