Upgrading my xbox

[zaqxswcde]

Thanks for all the help. I got slayers evox and installed it and it seems to be working fine. I just have a few queries. I tested copying a game to the hd and it worked and i can play it, but i can't delete it. When i go to hd management it says something like 'you chip does not support this feature' or something. Also, I have a executor2 with bios 4900 (around there anyway). Should i be worried about updating the bios? The warning message kinda scared me off it cause i'm not too sure what i'm doing. I had a look through the readmes but i can't seem to make heads or tails of it. Any help would be great. Thanks for your time.
