Fixes & Enhancements
- Fixed the issue where Reboot Bypass does not work after rebooting the system. This issue occurs when you set Password Bypass from Disable to Reboot Bypass in the BIOS setup menu and install Dell Command Monitor (DCM) version 10.7.0.232.
- Fixed the issue where the system does not boot into the Preboot Execution Environment (PXE) when the Wake on Lan feature is enabled in BIOS. This issue occurs when you use the Dell Command | PowerShell Provider to enable the ForcePXEOnNextBoot option.
- Fixed the issue where the key stops working when you press two keys together continuously. This issue occurs when the Dell KB522 keyboard is connected to the USB Type-A port.
Important Information

- The Watchdog Timer option in BIOS Setup must be disabled before updating the BIOS.
- BIOS updates take no more than 5 minutes to be installed on your system. You can install the updates in the background while using the system.
