Re: Advice for new travelling server: Intel Z690 chipset?
Many thanks for you extensive answer.
I agree with your observation that with both networking and display being unknowns it could be an issue having only one PCI-e slot to play with. But I can live with networking via a USB-dongle, at least for a while.
So I took the plunge and got the NUC. It arrived yesterday.
A very nice box. A pleasant surprise was that NetBSD can use the built in graphics as an genfb0, with output via both HDMI and USB-C working nicely, so there is no need for a separate graphics card. And, when connecting to the display via USB-C I suddenly discovered that the display just happens to have a built in ure0 that I had not noticed before. So, at home, there is not even any need for the USB dongle.
The only fly in the ointment is that running NetBSD 9.3 with Xen 4.13 the hypervisor complains about the CPU being unrecognised. When trying Xen 4.15 the CPU is recognised, but then the hypervisor crashes just as it is about to handover to NetBSD. But that’s a topic for another list, and I’m sure it will get sorted out.
