What's the role of this PAL?

I got a few cannibalized socket 8 boards and this one is the most promising, it's missing the PAL.
What exactly does this do? It's this board, chip is between the ISA slots:

What's the role of the V60X/U41-2 chip? I'm asking because I only need the board for CPU testing and nothing else. Not even extensive testing, just BIOS level.
Will it run without the PAL?

Just try it.

It might help tracing the connections from the chip´s data inputs/outputs to find out what it´s purpose is. The physical position between the ISA slots needn´t mean anything. Chips are often routed to "remote" locations to make full use of the existing space.

Since board has a creative audio chip, the PAL chip must be a bus arbiter, it shares the bus between one of the PCI/ISA slots and the audio chip.
so without the PAL chip, audio and one of the PCI/ISA slots won't work.
