Okay, first of all, you dont need to resize the bios, if you want to use the Executer bios that allow you to ftp, just choose a bank they will fit in, in their original size, use a 1mb bank or a 512 bank depending on which size bios you are using.
Also, i have a thomson drive, and they will read certain, cdrw, so if you have a mate who has got a cd burner, get hold of a traxdata x4 cdrw 80min/700mb disk they work fine in my thompson, and get him to burn you a copy of evolutionx onto it.
Also, first things first, you need to verify that you have actually got your xbit working, so dont worry about ftping or evolutionx at first get hold of an evox m7 bios, use xbtool to colour the xbox logo, flash it all the 256k banks in the format 6 and just make sure that you have got everything working right, when the xbox boots to the hacked bios, you will then know that your install is sucessful and you can then reflash one of the banks with the bios you need to ftp and away you go.
Dont try and rush your install, a lot of people are making the mistake of putting the xbit in and then trying to boot straight to evox cds or ftp straight away, without making sure its all working right.
Keep trying though, i have installed 2 XBITS and both of them didnt boot to my hacked bios straight away, but after a couple of hours of reseating and scraping d0 points, everything was fine.
