The probe code can't handle it. The case in question has something like: -------------- | CFI chip | -------------- | BIOS chip | -------------- | CFI chip | -------------- You could hack up a map driver that appears to have the two CFI chips contiguously, and then the probe code would find them both and make a single MTD device from them - but there was a reason why he wasn't doing this. Perhaps the 'BIOS' bit is in fact the beginning of the second chip, not actually a separate chip at all? I don't remember. -- dwmw2
