This came up on irc (#openbios at freenode.net) now...

I asked about the 3.3V vs 5V roms, and i only got further confusion...

This is one of the later lines written there:

< segher> there are SPI chips with at least three different voltages. 
          same for CFI.  FWH, i dunno, FWH is some wacko intel shit
< segher> and then there are flash chips from before CFI, too
< segher> the older of which require *two* voltages
< segher> oh and there also are LPC flash roms

If anyone can bring clarity, please do, and please make it extensive 
enough so that afterwards everything can be bundled together and stuck 
on the wiki.
