Oh. :(
I guess it is pretty much established, that it's all about two plcc in parallel with #CE activated individually. not that difficult after all.
Definately. This goes for any flash. I made http://stuge.se/ceswitch.png when discussing this with Anton Borisov.
(Note only one switch should be closed at a time. I had no better symbol at hand.)
using a flip over socket avoids cutting the #CE line on the mobo if there is no chipset output driving those 2 #CE signals.
True, but there usually is.. Right? This is especially true on buses where more than one device is attached. E.g. LPC, with both the flash and a superio.
the Gigabyte patent also includes the firmware procedure to verify flash content and to automatically select a valid chip without user intervention.
Yeah, it was using a watchdog that had to be disabled by the first BIOS software tried within a certain time. If not, the system would reset and try the other BIOS.
maybe one day they ship M57's with full dual bios : one legacy and the other LinuxBIOS activated by default YEAH ! :-) --Q
The big money win is when LinuxBIOS is the default and the other one is blank, then the board will cost $10-$15 less. (License fee Gigabyte pays for the Phoenix BIOS.)
Having the full dual BIOS circuit populated would be nice, but I'm not sure all their customers would want to pay even $3 extra for it, since they would never use it.
It's already very cool that it's so simple to add the manual switch to the board!
