Hi Arnaud,
Excellent news! I see from Wikipedia that the SS-20 would only support a maximum of
512M RAM anyhow, but it seems qemu-system-sparc doesn't detect this correctly as the
maximum address doesn't look right. For the moment I'd simply say "don't do that" and
I'll try and find out a way to have qemu-system-sparc fail on a more friendly way.
Also note that that target/sparc is not MTTNG enabled so your 2 vCPUs are currently
running on just 1 physical CPU. It's something on my TODO list to look at but fairly
low priority right now.
As for CG3 due to memory constraints in OpenBIOS you can only run it at a maximum of
1024x768 unless you have a real Sun PROM and a CG3 FCode ROM which will allow it to
run at the higher 1152x900 resolution.
ATB,
Mark.
