Green board is a Gigabyte GA-8SIML, and there is a stock GB BIOS.
Almost, its SIS651 mobo, OEM for PB. SIML-NF11Ai
8SIML bios should work.
If you're skeptical, just take the PLCC bios chip from a scrap board, flash it with the stock 8SIML using flashrom and test it on the 8SIMLNF. You have a removable BIOS socket, which should take care of not being able to recover in case the new flashed BIOS chip doesn't play with the board.
