CC-SA should be fine :-)

Almost all the chips I have handy are DIP anyways, and most of the PLCC
ones I have around are just PLCC versions of standard parallel flash, as
far as I remember, 28/29Fxxx stuff.
What numbers do FWH/LPC chips tend to start with?
I've read about LPC some, a long time ago, but I need to read some more!

That was my line of thought too. I'll have to play with eventually.

PS - do any newer motherboards use I2C flash? or is SPI the only serial
implementation used?
