Can Anyone Identify This Mod Chip???

[ANDRSAUN1]

a few months ago i pressed the eject button and nothing happened so i pressed it again and it opened, i put a backup in and the game started but wen i went to load a saved game my xbox crashed? i reset it and this time nothing loaded i just got a black screen, i pressed eject a couple of times to get to the evo-x menu and then clicked on microsoft bashboard and my xbox froze again! i was getting the same prob every time and then i started to just get a black screen when i turn my xbox on/insert disk etc but after a few attempts i managed to get evo-x to load and had no crashes on that menu, i inserted the exox disk and tried reinstalling it (i had probs b4 with evox-when i went to load the microsoft dashboard, evo-x wld just reload everytime but it worked once i reinstalled it) but this time the installation froze so i restarted and tried to load the microsoft dashboard which worked this time but froze when i tried to load one of the 3 options i allso got this error message once when i tried to load microsoft dashboard:
Error Code 21
5-9 HDD error
10-12 DVD error
13 Dashboard couldnt b launched
14 generic dashboard specified error
16 dashboard files/settings incorrect
20 dashboard was launched but failed
21 generic, unspecified error
the main light was also flashing red

i brought a new hdd with evo-x allready installed but got the same probs when i booted my xbox so i think it must be down to the cheapermod ive got at the mo
