XBMC4Xbox

Well, I ordered the equipment to do the Chimp HDD upgrade. I open my xbox, connect the power splitter and both HDD's. I go to boot my Xbox and the fans start up, but then it beeps and the LED flashes green/red. I unplugged the new HDD and the splitter, but it STILL does the same thing with my regular HDD. Did I fry something?

Merry Christmas!
This appears to be a hardware issue, but I'm not an expert on this sort of thing.

Personally I would:
#1 - Check all the cables and re-seat every connection.
#2 - Turn on the display and see if there is an error code you could use against the list. (I've seen a list of the errors posted in these forums. Just google for the xbox error codes and do a little research if you are getting one.)

As I recall I had to replace and IDE cable to make the error I had go away. Perhaps you damaged a cable like I did?

Your not meant to connect the HDD until just before launching chimp

I know, and after realizing my mistake I put the cables back to normal like I said. But it still refuses to boot.

EDIT: wtf, it boots without a hard drive, but then nothing happens--because there is no hard drive

You may have damaged some cables, it happened to me, just reconnect everything try to fix anything you might have broke

Check the IDE cables, and ports on the motherboard, you may have bent a pin

Also check your clock cap, it could be that's leaked all over the board & it's a coincidence it happened at this time.

Did you change any jumper settings on the drives? By default they should both be set to CS cable select.
