High Sierra HP Probook 4540s

I am trying to install High Sierra on an HP Probook 4540s, my bios is f.60 and I only find the new version f.67.
Does it only work with f.61?

HP Probook 4540s
i5 - 2540M
8GB RAM
intel HD 3000
Atheros 9485

Thank you.

Simply try and let me know, that's suppose to works anyway
I said Bios F60 because its a known working bios

With f60 many times it gets stuck while booting, I'll try with f67

Get stuck while booting not really useful infos

Sorry for my english.
It's so slow while loading High Sierra (apple and bar screen) and so many times it get stucked.

When it finally works doesn't have wifi. I have managed to fix the sound problem thanks to another forum message.

I upgraded to bios f67, the installation has not failed, but it keeps stuck when booting on the apple and bar screen.

Falled not failled ??

Strange because ⇛ ⇛ 4540s works like any other HP Laptop

Since the last installation always stuck, never finish the first boot after installation

You have to follow instruction and of course This site

I have tried again with Mojave following the new videos and finally the installation is done Only the problem that there is no sound. Thank you very much.

Audio Fix for 4540s is voodooHDA 2.9.0-V12 option 1 UEFI/ESP
Only remove AppleALC.kext in 10.14 folder when EFI mounted by voodooHDA installer
Reboot done

VoodooHDA 2.9.0 V12

Does this version of voodoo support HDMI audio yet or do we have to modify plist still to only deal with onboard and let apple hda do HDMI?
