Known issues:

• DALLAS RTC coin cell empty

The motherboard's Real-Time Clock (RTC) chip contains a coin cell that may have drained, causing the loss of CMOS settings. This can result in an inability to save settings, causing system instability or failure to boot. To fix this, the RTC chip can be replaced with an equivalent or repaired by cutting into it and soldering on a new external coin cell holder. Replacement guides are available at https://github.com/necroware/nwX287 or https://github.com/necroware/nw12887, depending on the actual chip used.

Notes:

clock module - mainboard does not boot with flat battery. Battery is part of ODIN time and memory module, so whole module needs to be replaced to be able to boot, not possible to skip/proceed like on some other mainboards. Fortunately, on my board (rev 1.1) module is in the socket, so it is very easy to change without any soldering. I used some alternative module from ebay with CR1220 battery inside. Just because of precise socket in mainboard, I had to put some ordinary socket between to be able to plug in.
CPU setup - in mainboard manual is mentioned support for 3,3V DX4 CPU but not mentioned any voltage settings. I've investigated and foud that mainboard can detect 3,3V CPU by grounded CPU pin S4. It can be also grounded by JP30 and this way 3,3V can be forced.
