It doesn't prompt to the right directory. It shows this path: C:\\windows\oem\ if i remember correctly. But when i click OK it doesn't install the driver because i guess the driver is not there. And i have to browse for the driver on the usb drive. I am using the second method when integrating the driver packs with DriverBase and i integrate all packs available. I hope this is the right method. If that is true then the path is wrong. The double-slash needs to be single. C:\\windows\oem\ C:\windows\oem\ That is the root cause of the problem. Our DriverPacks (Mass Storage) include both iastor.sys and iastor7.sys in the \D\M\I7 folder for use by the XP installer. As long as the path is set correctly, both files will be found.
