Bigger address busses are sometimes used; x16 flash is also sometimes used (and shared data/address busses, too). I agree you don't see these often on x86 PC boards though ;-) > CFI is the Common Flash Interface as developed by Intel and friends > and published by Intel.

And 32-bit wide. Not that you'll likely ever see that on an x86 PC :-) Segher -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
