Hello Finn,

Thanks for finding the required steps to boot NetBSD on MIPS Magnum. I was trying to find how to let it work on non-configured machine since some days!
You indeed need my patch at https://lists.gnu.org/archive/html/qemu-devel/2019-12/msg05037.html

My test for networking is:
- Terminal type = "vt100"
- (S)hell
- ifconfig sn0 10.0.2.15 netmask 255.255.255.0
- route add default 10.0.2.2
- connect to ftp.intel.com: ftp 192.198.164.82

Regards,

Hervé
