Gentleman.. we have a total recovery option to test...

DIY comming:

Format an SDCard.

Grab acllaim_update.zip

put these on the / folder of the sdcard.

xLoader=MLO

u-boot=u-boot.bin

recovery.img=flashing_boot.img

acclaim_update.zip

total boot from SDCard. This is wonderful. Now we can really begin screwing things up :)
