[flashrom] JIDA CMOS

Hi Marc,
I ran into the same problem when I automated flashing the BIOS followed
by running nvramtool to set the CMOS values.
The settings do not hold if you power down the system, however, they do
hold when you reboot the system via the "reboot" command.
Give it a try,

Hi Bill,

Yeah tried it. Like you, my testing was limited but not so
successfull. I can read and write to the NVRAM using nvramtool (it
doesn't output any error message so I guess writing was successfull)
but it doesn't seem to have any effect when I reboot.

For example, if I dump the content of the nvram to a file, reboot,
change a couple of settings in the BIOS, rewrite the nvram with the
dumped file, I do not get my old parameters back. It doesn't seem to
have any effect.

These are my observations so far.

BTW, I use the ETXExpress-PC module.
