If bank 0 is ok then boot with bank 0 this is the Linux bios so you need Eurasia to flash this. Before inserting the bios Disk flick the switch to bank 1.
Don't flash it with 3.03 Cromwell on bank 1 as you are just going back to square one and will have to flash it again. Flash the hacked bios right off to bank 1 using the flip switch trick.
By the way if its says searching for DHCP your network is not "Good"
