I finally had a chance to work on this again. Anyways I have tried all of the utilities that were referenced earlier and most of them will work on later Dell's. However I could not get any of them to work on the GXi series. I have also dumped the entire bios section and extended bios section from memory (thanks to the memory map available on dells site). The serial number was not found anywhere in any of the dumps. This leads me to believe that you cannot get the serial number from older Dell's. Although if you run the BIOS setup it will report the serial number. I wonder if it is stored somewhere in un-addressable memory. I may just write the scripts without support for older Dell's.

Thanks,
Mark
