xbox turns on/off/on/off on the third time it stays on and the light in the front starts flashing red and green please help!!!!

i recently installed an executer 2.6 mod and everything was going fine untell i was in the load bios from cd part the bios cd was already in the drive when it ejected i thought this meant the bios was not burned right i then tuned the xbox off but then i relized it ejects automatically my mistake. anyway now when i turn my xbox on with the mod on it turns itself on/off/on/off on the third time it stays on and the light in the front starts flashing red and green and there is no picture on the screen. i am new at this and REALLY would appreciate it if someone could help me out.

 

I no longer need help with this problem i took my xbox apart, uninstalled and reinstalled the mod chip now it work perfectly it must have just came loose anyway crisis averted.
