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 http://marc.info/?l=linux-kernel&m=127498023108564
