ok, i have followed every instruction and got slayer to work, i have flashed the mod chip(2.3blite+) with the latest bios i have a 160gig Seagate HD. and i locked the Hard Drive with Config Magic. Now i want to play XBL with legaly owned games. How do i go about doing that, because every time i turn off the xbox, turn off the modchip and turn the xboxback on( with the mod-chip still off) i get a error 13. Any Ideas?
