Or make a guess and see if it works, or STFW for someone else who figured it
out, or read chipset docs, or see if the SPD addresses correspond in a
sensible way, or extrapolate from another board with the same NB and
BIOS vendor, or...

One of the big advantages of Linux/*BSD over certain other x86 operating
systems is they don't try so hard to be user-friendly that they're
expert-hostile.  "Your computer is fucked up, please consult your
system administrator" isn't much help to the poor system administrator.

So while it's fine to *try* to translate to a DIMM slot using BIOS info,
please also report whatever can be figured out without trusting the BIOS.
So if I find it's in error, I can report everything needed to write
an override table entry.

Without the BIOS, it's a PITA, but the correspondence between /CSx lines
and DIMM slot locations can be figured out, and if necessary, I can publish
a web page with the mappings.

	"We do not trust BIOS tables, because BIOS writers are invariably
	totally incompetent crack-addicted monkeys. If they weren't,
	they wouldn't be BIOS writers. QED."		-- Linus
