It's ok in most cases, but I wouldn't call it reliable.
Eg:
Handle 0x0001
DMI type 1, 8 bytes.
System Information Block
Vendor:
Product:
Version:
Serial Number:
Handle 0x0002
DMI type 2, 8 bytes.
Board Information Block
Vendor:
Product:
Version:
Serial Number:
Seems quite a few motherboard vendors can't be bothered filling
in the fields, and just leave them in the state defined in the
code from Award/AMI/whoever. I've also seen examples where all
the fields are xxxxxx 0123456789 etc..
On newer systems some of the ACPI tables also contain board
specific ID's iirc. In the RSDT on this Athlon board for eg,
it contains "ASUS K7V-RM". I've not seen any of these that
have been incorrect yet, but I'll not put faith into a BIOS
vendor not screwing up something this simple.
(This table is easily parsable btw, no need for AML interpretors
and other ACPI evils)
