I just have a few questions, and I can't seem to find the answers via searching...
First off, I sort of understand how to use XBtool, and I've used it to create custom bioses for my X2.2Pro.
I've softmodded a v1.0 xbox (audio exploit) and what I'd like to do is create a custom bios for PBL (since all the ones I have load 'default.xbe' from some strange directory. But, (and I'm sure you've heard this before...) whenever I use a different bios in PBL, it freezes. And, I can't open the bios that came with it in Xbtool (because the kernel extraction failed...you already know that though)
I tried adding the RC4 key from boot.cfg to debug.ini and moving debug.ini to the config folder for Xbtool. It didn't seem to make any difference.
Can someone give me some specifics as to how to create a new bios for PBL? (or how to edit one that is included?)
Also, what does the BFM flag do exactly? I know it's 'Boot from Media', but does that mean when this bios is loaded it will (and this seems too obvious) automatically boot whatever is in the DVD Drive, and if that flag is not checked then it WON'T automatically boot whatever is in the DVD drive?
And finally, from what I've read, v1.0 xboxs use a 1mb bios and v1.3+ use a 256k bios. So, am I correct in assuming that if I soft mod a v1.5 and use PBL I need to use a 256k bios?
