Hi, I added some lines in TXTSETUP.SIF in the "i386" directory. These lines load the fasttrak drivers to escape at F6 key at startup. The sky was blue until i try to start my setup by windows setup program. This program copy some file in a directory on c: and restart computer for installation. BUT this stupid program don't copy my beautiful file frasttrak.sy_ in directory. In result, setup abort because one file is missing. i think my problem comes from the TXTSETUP.SIF, maybe here : [sourceDisksFiles] fasttrak.sys = 1,,,,,,3_,4,1 because these lines force windows setup program to find my file [sCSI.Load] Fasttrak = Fasttrak.sys,4 Somebody know how solve this problem ?
