Dell 24 all-in-one compatibility with Chrome OS Fllex

[Donald Asp]

I am trying to determine compatibility with the Dell 24 all-in-one and in checking the Chrome compatibility chart it indicates  that Chrome OS Flex is compatible with the Dell Pro 24 All-in-One QC24251 raptor lake as of Chrome version 139.  My question is what BIOS settings need to be changed in order for installation of Chrome OS Flex on the Dell 24

• Update BIOS: Ensure your device's BIOS is updated to the latest version available from Dell's support website.
• Reset to Defaults: Start by resetting the BIOS settings to their factory defaults to ensure no conflicting legacy settings interfere with the installation.
• Boot Mode: Set the boot mode to UEFI (Unified Extensible Firmware Interface). Chrome OS Flex typically installs successfully with UEFI mode enabled. If you encounter issues during installation, you might try switching to Legacy mode as a troubleshooting step, but UEFI is the primary recommendation.
• Boot Order: Change the boot order or use the boot menu (usually accessed by pressing a specific key like F12 during startup) to prioritize booting from your Chrome OS Flex USB installer. You may need to enable "boot from external media" or "USB boot" options.
• SATA Operation: If you encounter installation issues, check the SATA Operation (or similar named) setting in the System Configuration menu and select AHCI (Advanced Host Controller Interface) mode instead of RAID or Intel RST.
• Secure Boot: You may need to disable Secure Boot initially to boot from the USB installer, though Chrome OS Flex should work with Secure Boot enabled after installation in UEFI mode.
• TPM: If your model supports the Trusted Platform Module (TPM), clear and enable the TPM before installation to facilitate device enrollment after the OS is installed.
