Modifying GRUB to read DMI data

[W. Michael Petullo]

I am interested in modifying GRUB to read DMI data from my BIOS  
(i.e., the data dmidecode reads). The SMBIOS specification seems to  
state that the Plug-n-Play function interface is deprecated while the  
table-based interface requires a processor running in 32- or 64-bit  
protected mode. Does anyone know where I could find information on a  
non-deprecated method to read DMI data while in real mode?
