Request to publish Dell 15 DC15255 BIOS updates to LVFS (fwupd) for Linux
Hello,
I own a Dell 15 DC15255 (Service Tag: <YOUR SERVICE TAG>) and run Linux
(Fedora 44). I'm asking Dell to publish BIOS updates for this model to the
Linux Vendor Firmware Service (LVFS, https://fwupd.org). Linux users could
then install them with the standard fwupd tool.
Dell already publishes BIOS updates to LVFS for Latitude, Precision and XPS
models. This laptop already supports UEFI capsule updates: fwupd detects the
system firmware through the ESRT (GUID ed90dab1-73e3-4ff7-9094-fc08ba45b220).
The only missing piece is the firmware being uploaded to LVFS.
System details:
- Model: Dell 15 DC15255, SKU 0D7C, board 0HNX33
- Current BIOS: 1.10.1 (05/25/2025)
- CPU: AMD Ryzen 3 7320U
Could you please send this request to the team responsible for Linux and
LVFS firmware publishing? Today the only way to update the BIOS without
Windows is to flash it manually from USB through the F12 menu. That works,
but it means most Linux users miss security and stability fixes.
Thank you,
Chino de Oro

BIOS firmware is hardware based and is independent of OS. There is no BIOS for Windows nor BIOS for Linux. Updating BIOS firmware outside of operating system, from a USB drive and one time boot menu is the correct and efficient way.
At this current time, here is the latest Dell 15 DC15255 System BIOS, version 1.13.0
Updating the BIOS from BIOS Boot Menu (independent of operating system)
Note 1: Before updating the BIOS, ensure that you suspend BitLocker encryption on a BitLocker-enabled system. If BitLocker is not enabled on your system, you can ignore this step. For information about how to disable BitLocker, see How to Enable or Disable BitLocker with TPM in Windows at support.dell.com.
Note 2: Do not turn off the power or interrupt the BIOS update process during the update.
Note 3: Your system requires a restart after installing the BIOS. The restart can be deferred but must be completed to ensure that the update is installed.
Installation
1. Copy the downloaded file to a USB drive. You do not need a bootable USB drive.
2. Insert the USB drive into any USB port.
3. Power on the system.
4. At the DELL logo screen, press F12 to access the one-time boot menu.
5. Select BIOS Flash Update in the Other Options section.
6. Click the ... button to browse the USB drive to locate the downloaded file.
7. Select the file and click Ok.
8. Verify the existing system BIOS information and the BIOS update information.
9. Click Begin Flash Update.
10. Review the Warning message and click Yes to proceed with the update.
The system restarts and displays a Flash Progress bar at the Dell logo screen. The system restarts again when the Flash update is complete.
