how do i upgrade my BIOS?? im trying to upgrade from "evox d6 eject fix" to "X2 4977". I FTP’d the file over to the xbox hd, and chose Flash BIOS from evox. just got it to where i had to push "y" to flash the chip...so i did. the green bar started going then got to a point that it just stopped. I just waited about 5 min and it was in the same place. i tried to turn off the xbox then restart it. It started but kept trying to boot then the green light started flashing red and green. I turned it off again and turned all of the switches OFF. it came back on as usual. When i tried to write the new BIOS, i had switches 3+4 on. I dont want that to happen again cuz it scared me i thought i fried my chip. please tell me what to do. And am I supposed ot just send over the 512 kb file, or the 1mb file I made with X2BM?
