Net boot config in place for an older SPARCStation 20 and it works :

https://mail-index.netbsd.org/port-sparc/2026/05/27/msg003199.html

Now then the real problem is what to serve to the DEC Alpha to get
it to net boot. I have no clue where to start on that and no clue
what the firmware/prom commands would be. Also .. what the heck is
the network port? I have the 100Mbit in there and the original 10Mbit
thing is in there also. This is all just like puzzle pieces with no
picture on top.
