Hi,
I've got a very similar laptop, also a Dell 5558, but I'm having issues getting started. Perhaps the wrong version of the bios?
I'm trying to set the video startup memory
After some trying I was not able to find the setup key in the bios that was described. I finally managed to get booted to EFI and setup_var isn't recognised as a command.
I'm on bios version A10.
Has anyone else had similar issues?
Got the efi shell:)
now looking for the variable name to set video memory
Got it! I found reference to 0x15b and 0x15c, tried both, 0x15c left the system unbootable, I think that must be just for dedicated graphics, I only have the Intel. got it up running and 0x15b set at 0x3. Windows reports 192mb but I confirmed 0x3. )
Wish me luck, haha
