Hey all hope everyone's good.
So,
1. what is the reason base 56 is usually recommended for slot 249 while base 57 is recommended for slot 250?

I think I understand that base 56 offers the fastest USB access time but base 57 seems to offer the best compatibility at 95%+ (and the speed diff btw. 56 & 57 is apparently negligible) so
2. why not only use base 57?
3. And if indeed you only need base 57 which slot does it work best with, 249 or 250?

Or
4. does it not necessarily matter what slot a cIOS is put in (provided it's over 200) but really what matters is the version of cIOS that goes into a slot as well as the base in that slot

If that's the case
5. then how do you determine whether to use cIOS d2x v8 or v10 beta r52?
6. and whether to use base 56 or 57 for which cIOS

Final questions I swear!!!
7. Could I install v10 beta r52 in BOTH slots 249 & 250 & use base 56 for one slot & base 57 for the other?
8. which slot would be preferable to assign each base to?
Ok that's all I got. Thank you all!!!

Sorry if this is dumb or if I'm misunderstanding how this stuff works. I'm just trying to learn more both so I can hopefully help out others in the future & because I'm curious.
