Depends. We currently use dmidecode to get some BIOS stuff.

Does your GUID appear in the output of dmidecode?

I get:

System Information
        Manufacturer: TOSHIBA
        Product Name: Satellite Pro A10
        Version: PSA15E-01PJY-EN
        Serial Number: X3890390G
        UUID: 684xx80-xx30-1xx1-80xx-B1xxx389xxxx
        Wake-up Type: Power Switch

If a UUID == GUID you can use smbios.system.uuid to get at this data.

Richard.
