There are always lots of folks that wind up having a fraggin xbox due to flashing bad bios files to their tsop..Now this is not a tsop tutorial, there are plenty of them, this is more like an addendum...I would like whatever i miss for people to add what not to flash to a tsop....
1.) DO NOT flash an Xecuter 3 (X3) bios to a tsop, ever...There is no reason to even try this, there are plenty of X2 bioses out there, use those if u need an Xecuter bios.
2.) DO NOT flash a Boot From Media (BFM) bios to a tsop, these are for softmods, key words here are boot from media...usually they will be xboxrom.bin files...Just think, if you got the file from a softmod gamesave package, don't use it.
3.) If you are not using raincoat .7 to flash ur tsop, please pay attention to the bios size you need, for 1.0/1.1 you need a 1MB bios, for 1.2-1.5 you need a 256k bios...This will save lots of people having to do the 3 wire trick.
