what happens when you swtich banks?
4980 is an old bios, grab the 5035 X2CL

when you boot is the eject led green and then flashing red, or just a solid red
in which case you might have messed around with the eeprom
someone else with alittle more knowledge about the eeprom (if thats the case) will be able to help you out, as i'm not familiar with that stuff
