I've been reading all night, and trying to make sense of lines like the following: [SourceDisksFiles] satadriver.sys = 1,,,,,,?,4,1 satadriver.inf = 1,,,,,,?,20,1 Above, the seventh field ? (newfilename) is one of the things I'm thoroughly confused about. Per several documents I've read that the first seven fields are this: sourcefile.ext = diskid,subdir,upgradecode,newinstallcode,spare,spare,newfilename However, per this image, this seventh field represents the [sourceDisksFiles] section which is outlined at the beginning of the txtsetup.inf file. _1 through 6_ all look like they equal the same thing. What's the difference? I see different values being used below, but I don't understand why they seam to equal the same thing from what is shown at the top of the file. It would be nice to find a link that completely explains the syntax of the entire line for a file in the [sourceDisksFiles] section. The reason for this is I'm trying to add additional RAID drivers to my own CD's, but the info on the forums is very diluted and full of posts which contradict other posts, or have incompatible ideas. I'm following the method outlined in the unattended guide. They use 3_ for this field there, and I've read that _x means the file is uncompressed in the i386 folder.
