Notes

TrueOS

TrueOS using Installation from TrueOS USB img works in CSM mode without further tweaks.

• Boot into BIOS setup (hit F10 after power-on)
• Select "Advanced" tab
• Select "Boot options"
• Select UEFI Hybrid (CSM compat mode)
• Save config and reboot

During boot for installation:

• Hit F9 for boot device selection
• Select UEFI image
• Navigate to USB down to boot64.efi

Install as usual, reboot works without issues. Boot with "UEFI Native mode" fails when loading video, CSM is fine.

Boot

This laptop requires a recent FreeBSD 11/CURRENT/HEAD.

At the loader(8) prompt you must enter

set gop=4
set gop=0

before booting, otherwise you will have no video output.

For FreeBSD-12 this is

gop set 4
gop set 0

Video

You cannot switch video. The only way to get output on the VGA or DisplayPort is to close the lid before BIOS POST is done.
