i am going to flash my tsop.....and i go into the xbm2 and do the bios manager and insert three bios.....and as my last one it is the original with is 1mb.....then when i select it, i guess it downsizes it because when at first it says to big then it automatically adds it...did it downsize it or will i hafe to downsize it with another program.....i was just wondering because i want it to be xbox live safe

I believe the original MS bios' are just a single 256k bios copied 4 times to fill up the 1 MB chip.

hmm...but when i downlaod them it comes up 1 mb....i want other bios on there....so is it safe to cut these out by using the tutorial in the tutorial section??

So you can't flash the tsop with a single 256k bios? Or does it have to be 1mb to fill the chip?

Unless your Xbox is a version 1.2 with a Sharp TSOP you will need a 1 MB bios. That 1 MB can be made up of 4 256k Bios'. The Sharp TSOP is a 256k chip though.
