Hi Michael, Sorry if I am late, but only now I had time for read this: http://www.update.uu.se/~micken/ronetbsd.html
Extremely interesting and, at the same time, extremely fast to read, I have only one question: Have you created two more GRUB partitions (separate one from each other) to boot the 2 systems? it would be interesting to know more about the boot phase because honestly I can't understand if there could be problems related to the probe of the connected devices (like, if the 2 OS at the same time probe via PCI for the same hardware at the same time, could an error occur? for example something like "device busy, impossible to connect with it"?) It would be very interesting for an article about an advanced Fault Injection methodology that I've been thinking about for a long time. Let me know, Regards, Edoardo Mantovani, 2021 Il giorno ven 5 mar 2021 alle ore 14:02 Michael Grunditz < [email protected]> ha scritto: > Hi Edoardo, > > I have done something similar with RISC OS and NetBSD. but in that case I > did drivers in NetBSD for getting something to output framebuffer on.
