If you blew away the FLASH in the device then I doubt you're going to be able to fix it apart from sending it to Dell. I doubt there's anything wrong with the hardware - but they'll probably have to put it on the bench and "manually" reload the boot-loader. Probably will cost $100 or so to have it done but then that's cheaper than buying a new one.

Upgrading the BIOS on these guys is something best done very carefully (as you have obviously discovered). Sorry we can't be of more help - you went way past the red-line on this one.
