ndis(4) is removed from DragonFly; it’s probably been years since it was applicable to any hardware. I don’t think it will affect anyone – but it’s an interesting tool from a historical perspective; for a while it was possible to use Windows XP drivers to create a BSD network driver, effectively.
Sascha Wildner has added the PCI IDs for various recent ichsmb(4) devices. This I think just means a correct device name in dmesg, but unidentified smbus devices has plagued me for years, even with other operating systems.
So, if you find yourself in possession of an ADM-3A terminal, and want to attach it to a DragonFly machine, here is the /etc/ttys config (viewed on the ADM-3A itself of course) and the front switch settings that worked for me.
Apparently DragonFly used to disable IOAPIC when booting in a virtual machine. This helped with some old virtual machines, but broke newer ones. It’s now enabled, which helps boot DragonFly on Google Cloud.
