Ok is me again:(
ok i think i put the new bios in it. i saw the yellow and green status bar at the bottom of cramwell screen. After that was over the xbox shut off.
Does that mean that it was flashed?? what happend??.
Because after i turned back on i was getting the xbox logo and MS on both on Enable and Disable.
So what do i need to now??
please help.

What bios was it Evox M7?

Try using an evox boot disc, as you sound like you have flashed it already. If you didn't edit the M7 bios at all you won't notice any difference. Another popular option would be to get slayers, but you may as well learn it yourself. For more info click this link : Total n00bs guide to everything

the xbox shuts itself down after a BIOS flash anyway.
have you made sure that you used the correct size BIOS for your chip?

if i remember i had 4 blocks on that program that you import the bios from.

im guessing about what your talking about there...are you on about the bios manager where you make the bios the size that you want? If you are then im pretty sure youve made a 1MB BIOS, ensure that you chip accepts 1MB BIOSes

yes that one the bios manager.
i think it was 1mb bios. i had for of them.
on the chip i got a xcuter 2.3b lite.
what do i do know?
since i think the chip was flashed as you said that after is flashed the xbox shut down wich it did on my case.
