This I'm unsure of, I read reasoning that only 32 GB cards are supported because of the max size of FAT or something. I don't know if that's true or not. Plus, OpenBSD uses partitioning with a very small FAT partition for U-Boot and firmware. That said I have never tried running beyond a 32 GB card. > 3.

The 4B afaik takes a micro SD card. Some Pi's before it (the B+ for example) used a normal sized SD card. You can also boot OpenBSD off USB instead of the micro SD card (on the 4B). I do that with a SSD on an adapter (but it's slow). Here is a gotcha that you may not know. I have an old -current version from December running. The sound doesn't yet work with that version of OpenBSD afaik and I've been using a soundserver on my other Pi (a B+ running raspbian) over the network. It works out well, Youtube works with iridium browser. One more thing I've been using OpenBSD 25 years almost and the Raspberry Pi setup is one of the hardest setups I've dealt with. I'm not saying I'm a seasoned admin but I have quite a bit of experience, it once took me a full day almost to figure out how to get OpenBSD on the Pi. Patience is what one needs to bring, a lot of it. And good eyes to read the INSTALL doc. This is probably the last time I'm doing RPi support as I'm rearrangeing my workspace for electricity savings and the Pi will be gone in March at the latest (I'm reusing it with OSMC in the living room or something). I hope I was able to answer some questions. > Thanks, > Steve Williams > > Best Regards, -peter
