When running LinuxBIOS it isn't an issue, as LinuxBIOS doesn't write to the flash chip during bootup. > The original is 2Mbit (256kB).

It is much nicer to get a slightly larger chip and put two copies of LinuxBIOS in it. Of course support for that hasn't been implemented on the K7SEM :( This allows you to develop and play with LinuxBIOS without needing to use a special flash burner. Eric
