I installed the 2.6ce with no problems to a 1.0 xbox, pinheader install, everything boots fine. I thought it was odd that the 3.03 cromwell bios loaded off both banks before i flased the bios but i went ahead and flashed anyway. Flashed 5035 via disk to bank 2 and it did everything like it was supposed to, but after i restarted the xbox only cromwell 3.03, no matter which bank i'm set on. Could the switch be bad, I know v. 3.01 is supposed to be on bank 1 if i remember right, i already took the x box apart again and re checked all the plugs and connections. should I try reflashing? any suggestions would be greatly appreciated, thanks in advance.
