Also known as:
- BCM FM541
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:
Only up to 133MHz: NEC Ready 7022, 9022, 9522, and 9532; Powermate V75, V90, V100, and V133.
It is not clear what exactly is the difference between the FM540&FM541, until that time, they're listed together.
