Yes, I was, or actually, am doubtful as well. I would have thought, for sure, you can turn off the cs5530a's claim of reads on that address block. But so far I can't find any way to do that, and it doesn't seem like anyone else has either.
As for watching the chip select line, I'd love to do that but I don't have a logic analyzer or probes. I guess I could do it with an LED and a sharpened wire but I'd rather not risk damage to my board. :-) --- Richard Smith <[EMAIL PROTECTED]> wrote: > > > > Looking at Stefan's /dev/bios code I see the use > of 6 > > to enable write access to the flash.
