Any 256k BIOS should work. If your Xbox is a 1.0-1.5 have a look at iND-BIOS.5003, X2.4981 and Evox M8+. My personal preference is iND-BIOS.5003 because you can configure it from a text file on C without reflashing, but it's your choice.
If it turns out to be a 1.6 your only choice is Evox M8+1.6.
I recall a thread in the last 6-8 months about problems flashing some clones - you may want to do some more research before you start.
thanks for the reply its defiantly a pre 1.6 and i decided to check if i could flash it and i can im thinking a evox m8 for it
