Check the manufacturer's website for your Dell device. The BIOS update process typically involves downloading the latest version to a USB drive and using the BIOS setup tool, which can be found on the manufacturer's site.
It seems you're asking about updating firmware without a traditional BIOS setup. Dell offers Linux and EFI flashable firmware that simplifies this process, reducing reliance on BIOS updates. I recall seeing Dr-DOS used for similar purposes in the past. Are DOS flashable BIOS updates still available today?
There is a Linux distribution that has been available for several years. They have made the documentation accessible on their website. But it won’t function properly if your system is in "Legacy" mode—it’s EFI-based only. The link you mentioned seems to relate to the Dell Edge Gateway 5000, though it should work with most of their BIOS versions from recent releases. They also offer guidance on LVFS, fwupd, and similar tools. GNOME is one such GUI option, but I haven’t used it myself. To set it up, use your package manager and install fwupdmgr. If you don’t have it, check the Dell support site for instructions. Recent hardware like IoT, XPS, Latitude, Precision, and Optiplex are supported. For older systems not covered by LVFS, the vendor suggests customizing update notifications via their support portal. They manage 805 firmware files and recently uploaded several firmware update protocols including Dell Dock Fastboot Flashrom, Intel Thunderbolt, NVMe, Synaptics, and UEFI UpdateCapsule.
