You'd better take a picture of the board.

I found one that matches very well but there are some differences

I found the PB4 BIOS here: http://www.motherboards.org/mobot/bios/Abit/PB4/

If you buy some flash EPROM's that fit you might be able to hot flash it in a different board, or use uniflash and flash it in a network card with a boot ROM socket.
I've actually got a couple of flash EPROM's in the mail to attempt this with a couple of my own boards...

If you are squeamish, don't prod the beach rubble.

Thanks for that Donut I should give it a go although I suspect the board might be dead, it should beep with no bios chip?

Without a BIOS chip, the board will not work at all, not even a beep.

Here's a thread I posted on the topic:
Am5x86 on UM8810P

I haven't recieved the chips yet but I'll update with the results when I do.

But without knowing what chip was in there before its hard to tell exactly.
My board had 27C010A BIOS chips, I ordered 28F010A replacements (which are flash programable unlike the old ones) with the same pin count.

You can buy any 128k flash eeprom and use UNIFLASH for flashing; i've flashed 3 mobos with this program and no one was damaged, and if you have dead mobos maybe there is a flash eeprom in there, you need to perform 'hot-flash' to flash this mobo, if you need help, ask me
