CMOS battery and BIOS settings on a PowerEdge R430

Hello Alexander,

 

You are correct. If the battery is out for any length of time the BIOS would revert to defaults.

 

If you have the iDRAC Enterprise license you can Back up the server profile

Backup server profile

Use this licensed feature to perform the following and store the backup image files in a vFlash SD card:

*Back up the following:

*Hardware and firmware inventory such as BIOS, NDCs, Lifecycle Controller supported add-in NIC cards, and Storage Controllers (RAID level, virtual disk, and controller attributes)

*System information

*Lifecycle Controller firmware images, data and configuration, and iDRAC firmware and configuration

*Optionally, secure the backup image file with a passphrase.

 

I think the BIOS in the firmware inventory is just the firmware version. I don't see a way to back up the individual BIOS settings.

You may go through the BIOS and note down any specific settings or take pictures of the BIOS pages with the custom settings you have.
