Information from SMBIOS

Hello,

I am looking for information on reading the BIOS using
kernel mode code. Specifically, OEM information embeeded
in the SMBIOS table structure. The OEM information is
obtained from the System Tools program group application
System Information including manufacturer and model number.

From my search on the web, this information is from the
SMBIOS . Check http://www.dmtf.org/standards/smbios . The
information appears to be stored as a table which is
memory mapped to the physical memory. However, its
location is not specified. WMI also gets handles to this
information somehow.

I would appreciate pointers on how to retrieve this
information using kernel mode code in XP.

Thanks
