OpenBSD and laptop


Hello everyone!

I'm sorry for disturbing you and I'm a little bit uncomfortable because I'm not so active on forums and always trying to figure out something by myself (Don't want to disturb others).

I want to switch to OpenBSD, but I didn't find anything about hardware which is supported on OpenBSD (I'm not sure that I understand list of supported hardware in the F.A.Q. because there's not much about Intel).

Will OpenBSD run on a laptop with:

CPU: Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz (x86_64, GenuineIntel)
Graphics: Intel HD Graphics 4400 (Integrated)
RAM: 8 GB

Or there can be some issues? (I don't care about Wi-Fi)

Thank you all for your time!

I would try booting bsd.rd there and then look at the dmesg to see what the kernel recognizes. But off hand I would guess that it would be ok.

Cool

OpenBSD is quite good at identifying hardware. I'm running OpenBSD 6.8 on my T410 Thinkpad which has a 2.4 GHz cpu and 4 GB RAM. I'm happily running XFCE 4.14.
I suggest that you do a wired install of OpenBSD if your laptop has a RJ-45 connection. On first boot-up after your installation OpenBSD will automatically download any needed firmware for your wireless NIC, graphics card, sound card, etc.

Have fun!
As you're a Slackware user you are comfortable with manually editing configuration files. On first boot-up of OpenBSD on a wired connection you should see what type of wireless firmware is being downloaded and installed. On my Thinkpad it uses the iwn firmware.
To set-up a wireless connection after I've finished downloading what I want using my wired connection I open up a root terminal and navigate to the /etc directory and remove my wired connection script.

Code:
# cd /etc
# rm hostname.em0
Then I manually write my wireless connection script. I'll give you my example (removing the actual hostname and wireless password).

Code:
# vi /etc/hostname.iwn0
join nameofwirelessconnection wpakey wirelesspassword
dhcp
inet6 autoconf
up
Save and exit. On next boot-up your laptop will connect to your wireless hotspot.

Added later. Do read up on how to set-up OpenBSD before you install it. There are some configuration files you'll need to edit in addition to what I've mentioned.

I would move the wired hostname.if(5) to a back up file rather rhan removing. To find out if your wifi adapter is supported, identify the chip under your current OS, then have a look at relevant man pages online.

Yes. I neglected to mention doing a hardware compatibility check. I agree with cynwulf. It is a very good idea to find out if your hardware will work with OpenBSD.

What can I say. All works great, but I didn't tried wifi yet, because I don't use it and didn't tried to launch blender for 3D modeling yet, but I like already like OpenBSD. Only one thing I did wrong is installing OpenBSD on a whole disk instead of free space, so now I need to install Slackware again Thank you for your help!

Cool! I have set-up a dual boot with Slackware and OpenBSD; it works great. LILO plays nicely with OpenBSD. Here's a thread I created on that subject a while back.
