Pentium MMX200 G586SPA motherboard Sis 5511 chipset, Award bios Modular V4.51PG, Win 95.

This set was working OK. I tried to insert a PCI modem. It started the BIOS error of "keyboard error or no keyboard present. I removed the modem but same message. I tried different keyboards both AT and PCI type. There are voltages at the keyboard pins as follows: Pin1=4.2V, Pin 4=5.8V, Pin5=4.2V, however, when the power is switched on the keyboard light does not flash or lights.

Keyboard is dead and I can not set up bios, firmware or any other thing. What can I do apart from assuming it is the motherboard fault and throw it away.

Flash BIOS.

I copied an exe and bin files for the Award Bios on an floppy and started the computer with the floppy in the drive. Nothing happens. As DOS is not loaded and the keyboard dead how can the Bios can be flashed?
