Okay, so here's what happened:
I got my old 80 GB HD running in my new Xbox, but I wanted to start it over, so I popped in Slayers 2.5, and told it to reformat a big HD to F. It did all that stuff, then I rebooted, and it went straight to MS dash, though the LED was red, meaning the chip was on. After that, I figured I needed to reflash the chip in order to get it to boot from evoxdash.xbe first, so I popped Slayers back in, and flashed it to 256k X2 4977 BIOS. Now, after it shut off, when I turn it back on it stays on for a second, the LED is still green, shuts off, does the same thing again, turns back on and the LED is red/green flashing. Please tell me I didn't just fuck my chip, and that I can fix this. Thank you very very much...
