Here's my idea: I put in a USB key, it boots into DOS, determines which model the PC is, and runs the corresponding BIOS update. I have everything setup except for the "determines which model the PC is" part. Right now I just have a system of menus to keyboard through, but I would like to automate this. I know about HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\BIOS\SystemProductName, but is there a way to access this in DOS? Is there any other way to determine which model I have? I would be comfortable using a program to acquire this information as long as it runs in MSDOS, of course! Thanks for the help!
