Hello everybody i am new to this forum and also new at trying to make my own unattended windowsXP installation )) i searched through the forums and didn't find anything about something useful i think. what is the right way to remove from the custom installation all those drivers i think for my pc are useless???for example adaptec scsi etc that get loaded in the beginning of the installation. i also want to delete all ati drivers for example and so on...you understand? i found somewhere some cmd files but i would like someone to explain to me how the procedure works so i will be able to continue myself manually. i think i have to delete some lines from txtsetup.oem but as i tried i think i erased too many or something like that,or i didn't remove all the information needed so tha installation stopped saying that couldnt find some files. have i also to delete some PCI\VEN\... lines??? thanks in advance and sorry for bad english
