FWIW, this is "Manufacturer: Intel" and whatever device 0x18 is for Intel. IDs 2 and 3 are used by the pflash_cfi01 code only if we're using the bogus backward-compatibility "act like a bad emulation of two 16-bit devices making up a 32-bit wide device", in which case they're the ID values for the second of the two devices. (Or it might be that the ident values then are "manuf-id manuf-id device-id device-id", and with the not-bogus setup they're "manuf-id device-id unused unused".) I'm not sure whether the chips on any of these boards really are Intel ones :-) thanks -- PMM
