After installing the service packs to Win2k, the files SP1.cab and SP2.cab are in the Driver Cache folder along with driver.cab. When Windows discovers devices it looks in these cabs to locate drivers for the discovered devices. I have a bunch of IBM T21 and T22 laptops that dont install all the devices automatically, and I'd like to add the drivers from IBM to the cab files. Can I just extract all the files in the cab to a folder, add my drivers, and recreate the cab file? Has anyone already done this? I'm thinking there might be a stored checksum that needs to be updated also... Thanks - DR http://www.sunbelt-software.com/ntsysadmin_list_charter.htm
