Sorry in advance for the potential newb questions:
I've been using X2.4981 bois for a long, long time.
I've stuck with it because:
1) It prohibits connectivity to XB Live when in modded mode
2) I patched the BIOS prior to burining it to boot from F:\avalaunch.xbe. This allows me to keep my C: & E: partitions virgin. When I boot into unmodded mode, MS dash and Live are happy

Now, to my knowledge and the research I've done, I can't seem to find anything that tells me that X2.4981 will support 32k clusters.
It appears that M8 does, which is a reason to switch -- provided M8 also handles my two concerns listed above.
A) Does M8 block access to Live?
B) Does M8 boot from F: (is this customizable)?
C) If M8 does support 32k clusters, how to you enable that option?
Thanks in advance for your replies,
