will installation of EVOX 2.5 take away the need for a modchip?

if you can install evox without a modchip then you dont need a mofchip! :) get it? Ok ... in dummies term: If you flash the xboxs onboard bios with evox then you can remove your modchip.

so this means flashing the onboard bios with evox will allow the use of backups-originals without the need for a modchip? :)

you can only flash the bios when you have a modchip installed BUT then you may remove your modchip and still play backups
