That depends on the machine/BIOS. For vendors our scanner integrates with, like HP, that's pulled in as part of inventory. Example:
For other vendors, you'd have to find a way to identify that from windows, like WMI. You could then use custom data to pull that in. How you access that information is likely to change per vendor, or even BIOS versions within the same vendor.
Do you, or anyone else, have any suggestions as to where to start looking in the WMI for this for Dell computers (Optiplex and Lattitude) ?
