Dear Community.
I'm trying to run OpenBSD on a Clevo W840SU laptop. After a successful install
and starting the machine the BIOS hangs. That is, when the booting drive is
connected via SATA/mSATA. When connected via USB, it works just fine.
The identical laptop model is mentioned as a working one
in Peter Hansteen's blog (including a dmesg log) [1].
A detailed documentation of the issue is given in the plain text document
attached.
So is this a broken BIOS issue?
What else could I try to get this to work?
How to debug this issue further?
I've been using GNU/Linux before and have had not problem with a hanging BIOS
whatsoever. In fact it's still working without a problem on this machine.
Thank you very much for your attention and help.

OpenBSD 6.5 on Clevo W840SU: BIOS hangs when disk attached via SATA
===================================================================
== Error Description
=== With BIOS UEFI disabled
That is, BIOS Settings _Boot -> UEFI Setting -> UEFI Boot_ disabled.
* Successfully installed install65.fs from USB to SATA/mSATA connected disk
* With
** Fdisk MBR whole
** Disklabling auto
==== Result
1. Upon restart system hangs showing only the American Megatrends logo and
version.
2. CPU fan starts to turn up.
3. BIOS settings cannot be reached. (press/hold ESC key upon boot)
NOTE: Attaching the same disk via USB, BIOS boot does not hang, system can be
successfully booted.
=== With BIOS UEFI enabled
That is, BIOS Settings _Boot -> UEFI Setting -> UEFI Boot_ enabled.
* Successfully installed install65.fs from USB to SATA connected disk
* With
** Fdisk GPT whole
** Disklabling auto
==== Result
1. Upon system start screen remains blank (not black) and goes in a restart
loop.
2. CPU fan starts to turn up.
3. BIOS settings cannot be reached. (press/hold ESC key upon boot)
NOTE: Attaching the same disk via USB, BIOS boot does not hang, system can be
successfully booted.
== Machine Description
* Clevo W840SU
* American Megatrends Version 2.15.1236 2012
* ME FW Version 9.5.13.1706
* BIOS Version 1.03.02
* KBC/EC Firmware Revision 1.03.02
=== BIOS Settings
==== Advanced
* Intel(R) Smart Connect Technology : disabled
* Intel(R) Rapid Start Technology : disabled
* SATA Mode : AHCI Mode
* Boot Logo: Disabled
* Power On Boot Beep: Enabled
* Battery Low Alarm Beep: Disabled
==== Security
* TPM Configuration : disabled
== Things tried but did not work
=== Clear partition table
* Erase first 2M of disk before install

dd if=/dev/zero of=/dev/sdx bs=2M count=1

=== Initialized EFI boot files with MBR
See https://marc.info/?m=15190459022533
Step 1 : Initialize MBR
----
newfs -t msdos sdNi
mount /dev/sdNi /mnt
mkdir -p /mnt/efi/boot
cp /usr/mdec/BOOT*.EFI /efi/boot/
umount /mnt
sync
----
Step 2 : install openbsd -> choose "OpenBSD" configure disk fdisk step (which
supposedly does not alter the MBR)
Step 3 : reboot with and without UEFI enabled.
==== Result
* MBR after successfull install
