If anyone has a bad flash of a BIOS and cant recover, contact me. I have the hardware to flash LPC Fimrware Hub ICs used in the WebDT. Just cover shipping costs and send me a copy of a BIOS you know that works. I would be more than happy to help you out, no charge, although if you want to slip me a few extra bucks as a token of appreciation, that would be nice. If anything I might even be able to ship out a whole new BIOS chip, preflashed, but I would have to charge for the cost of parts.
I have a Willem EEPROM Programmer than can handle the chips used in the WebDTs, typically an SST 46FL0xx FWH. Keep this between you and me, but if you sweet talk SST they can send you some free samples of the chips used in the WebDT. I am also doing similar work with the WebTV 2 RM4100.
Here is a lil' image to spark your interest:

Let me know if I can be of any help.
This is my BIOS Build:
