Re: [coreboot] rtc wake up does not work on ASUS M2V-MX SE

[Jiang Wang]

Hi Stefan,

Do you have any suggestions about the specific name or keywords that I
should look for in the DSDT? I think I can dump the DSDT of the
manufactured BIOS with acpitool and compare it with the one of
coreboot, right? But it is better to have a rough idea before doing
the comparison. Thanks.

Regards,

Jiang
