Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅
known issues:
realtek alc3204 audio driver in win 11 compatibility issue i think
TPM device is not detected at boot, (everytime you boot) no option in bios to disable it
bluetooth device not working as it is not detected in bios
the device boots about 20sec. to display dell logo everytime
F2 is not working in windows but you can remap it
type c port is not working, download updated bios in dell 5400 windows version website to work
(i updated bios 5 times for testing) so i think its safe
other than that its usable
note: write down your service tag as you will enter it in bios in first boot
my board code is
EDB46 LA-H771P REV. 2.0 (A01)
PLEASE dont ask me anything about fixing issues as this is my first time doing this
you can also edit this bios to fix this bugs
try at your own risk, i`m not responsible for anything if you brick your device
backup your bios before flashing.
ec is not needed to flash as it came in the main bios
but you can also flash it
