Ok I have been running an older version of EvoX for sometime and also using the 2.5 err color ybox bios and want to update many things so I can get yxboxdash.xbe off teh c: drive. I havn't installed a new HD yet this I will be doing in about a week or so as soon as I get my hands on a 80-120GB drive. I am having trouble trying to find info on the following and any help would be great. And am basically just looking for verification that I am going to do this right.

Config as follows
V1.0 xbox
Matrix Mod
current bios 2.5 w/hacks
EvoX v1.8.2594 (yeah its old)
Boot to yboxdash.xbe

Now what I want to be able to do is boot to the evoxdash.xbe (v1.8.3752) on the E: drive for now until new HD
upgrade bios to 4976.02(is this a good one or should I use the D2 bios) but boot to E drive not F for obvious reasons.
1) can I do this
2) if so do I need to use the xbtool to hack the bios to boot to E:drive and after that I can move put the evoxdash.xbe on the E drive
3)will my modchip still be deactivated for live use if I hit eject with the 4976.02 bios.

I hope I don't get too flamed on this one but I was just having a few problems understanding the new bios and what it does and how the hacks work. Thanks
