Hello,
I have a small Sophos XG86w firewall here, which is still working so far. But there is a problem with the BIOS and the DMI environment variables.
The hardware forgets the date and time after a reboot or a power failure.
The DMI environment variables are also reset to default values.
I have now tried 2 different batteries (CR2032).
I reset the DMI vars via an EFI shell and with AMIDEEFI64 (v5.21.0057).
However, after a reboot or a power cycle, these values are reset again.
It is an Apollo Lake platform with an Intel Atom E3930
Where can I look for the cause on the board?
Is the eeprom defective?
thanks in advance
