flagmax Thank you for the help(copy and pasted it into my little diary of bios modding ) I will obviously be re-reading that a few times. Right now my minds a bit scrambled but I know after runningit through a few tiimes the picure will become clearer. The help is more then appreciated!!! ifndef edit: oh and yes you did clear up some stuff for me... I'm not as scrambled as before, starting to get the whole picture . Its one thing to just follow directions i.e. open cmd prompt type "cbrom xxxx.bin /isa dell.bin" and yor done and it another to know where that came from and why.
