Don't bother with Xtender or Xecutor1. Details on the other two families can be found here:
http://www.xbox-scene.com/bios.phpA 1.0 BIOS will work on a 1.0 Xbox, 1.1 BIOS on a 1.1 Xbox, and a MultiVer will work on both.
Every BIOS size is currently 256K, but it can be duplicated or combined with other BIOS binaries to combine a single larger image. You might have 2 x 256K X2 BIOSes and 2 x 256K EvoX BIOSes. This would be the same as 1 x 512K image of each. You can combine different BIOS images so you can easily switch between them. This is typically more a luxury than it is a necessity.
