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.
- Inadequate Power Delivery
This motherboard may have insufficient power delivery, which can lead to unstable or unsafe operation. In extreme cases, this may result in hardware damage, spontaneous combustion, or other electrical failures. Users should exercise caution and consider upgrading the motherboard power supply or other components to ensure safe and stable operation. The RetroWeb community may also provide guidance and assistance in mitigating this issue.
