The i386 should run using a suitable multiboot boot loader (iPXE etc). I am not sure about the gigabit ethernet because I could see the specific device. Note, libbsd has an issue on the i386 PC I have not looked into and fixed. The support broke with the recent upgrade to the latest FreeBSD version. > Given that we don't need any 64bit features, is it much work to start an > RTEMS application in the 32bit compatibility mode? 32bit mode should run.
