Mod a Pentium1 BIOS (Phoenix) to assign IRQ to PCI

This project is about modding/changing the BIOS for a device that uses a Pentium 1 motherboard. By default there is no PCI slot mounted on the motherboard but one can be soldered in (as well and 4 extra resistors) in order to get the PCI working, but the BIOS is not assigning any IRQ to the PCI card.
I want somebody that has experience with modding a bios to help me with this issue

Below you can find the unmodded BIOS. Please bid if you are confident you can finish this project
