Where to find older AM & Award bios chi

A storm resulted in a power surge killing 60 of our workstations. Unless we can find some Amibios/American Megatrends 586 and 686 Bios chips (1985-95), and Award pci/pnp586 Bios chips (1997), we are going to be in trouble. Our 200 station network isin a large secondary school…and exams take place in two weeks time. Any feedback will be gratefully recieved
