Pezzie >>> Thats great u got it fixed. makecab is a great tool, but how often will you use it after you finish making yoru winntbbu.dl_? I almost never have to make use of makecab until i started with modifying winntbbu.dl_ sonica >>> I have been editing my winntbbu.dll for a long time and i never had to use ModifyPE unless i modify my colors. In addition the pattern that has emerged is if u have the uncompressed winntbbu in your i386 that causes the problem. As soon as i get a larger number of feedback i will revise the guide. Until then the guide will remain the same. I don't want to update the guide until i get all the facts and statistics to back it up.
