Default OpenBSD on HP Stream 14 cb112wm

I have a refurbished HP Stream 14 cb112wm en-route that I intend to upgrade the ram memory to 8GB and install OpenBSD.


An observation, the HP Stream 14 an0xx and cbxxxwm spec pages say the ram is 4GB period. I did find youtube videos that show these models to have a single, replaceable slot (DDR3L1600/DDR42400) and a Tomshardware post that the an0xx series will recognize 8GB. I'm gambling that the cbxxxwm will too.

Opening these up entails prying the plastic housing and, if necessary, I would like to replace the wifi at the same sitting.

The manual indicates that it comes with 2 possibilities for wireless:
Quote:
Description
Spare part number
Intel Dual Band Wireless-AC 7265 802.11 AC 2x2 WiFi + Bluetooth 4.2 Combo Adapter (non-vPro) D1
901229-855
Realtek RTL8822BE 802.11 ac 2x2 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported)
924813-855
iwn(4) indicates support for the Intel chip and the Realtek RTL8822BE is missing from rtwn(4). I have had a good OpenBSD experience with RTL8188CE.

I do not have a problem running Current.

With that background:

1) Does HP tend to put hardware restrictions in the BIOS? If so do I need to purchase an HP Intel card or will any Intel 7265 card work?

2) I don't care about Bluetooth and would not have an issue buying an Atheros or other non-bluetooth chip. Reports of positive or negative experiences appreciated.

I will report the results in the forum OpenBSD laptop hardware section and nycbug dmesg.
