Known issues:

  • DALLAS RTC may be flat.

    The RTC chip contains a battery which is probably empty by now. This battery holds the CMOS settings. If your board doesn't save the CMOS settings, replace the RTC chip with an equivalent, or mod the existing chip. Replacements can be made following this https://github.com/necroware/nwX287 or this https://github.com/necroware/nw12887 depending on the actual chip used.
