There have been numerous updates to the BIOS since the one you have. You will definitely want to update it. The file is attached. I know many of your have the UUD2012. I have updated this to UUD2014 just to remove the EDO RAM Read speed feature because it does nothing on this motherboard and only adds confusion.
Is your BIOS an EEPROM or UV EPROM? If needs to be an EEPROM to be flashed. Some common EEPROMs which work well on this board are PH29EE010, W29EE011-15, or AT29C010A for 5 V. Intel P28F001 for 12 V. Generally, I think most EEPROM's with 29EE010, 29EE011, or 29C010 will work. Given the revision of your board, I suspect it contains a UV EPROM. You will want to replace that with a flasheable EEPROM. I use a Wellon VP-390 to flash my BIOSes and test my SRAM.
Also, if the battery in your RTC is dead, which it most likely is, then you will not be able to boot the MB. This is because your CMOS settings aren't being saved. You can work around this to some extent by using MODBIN to save all the settings you wish in your CMOS, then flashing this new BIOS image to your BIOS chip. But every time you want to make any changes, you need to use MODBIN and reflash the BIOS.
The fact that your computer no longer shows any sign of life is a big concern and makes me question whether putting in the effort to desolder the RTC and flash the BIOS is worth it. Desoldering the RTC on this board is not fun. I would practice on some known dead boards first. If your ESCD is messed up, then you should try PCI cards which you haven't tried at all yet, such as the GF2.
I recommend a single stick of RAM for troubleshooting - 8, 16, 32, or 64 MB. Ensure that it is FPM and not EDO. Set the FSB to 33 MHz and the multiplier to 3x. Use an Intel DX4 or Am5x86 for testing. Ensure that you only have a graphics card installed and remove the HDD. Even remove the floppy drive - people plug these in backwards all the time. Use 256K of double-banked cache.
Plan your life wisely, you'll be dead before you know it.
