Who dares awaken me?
Yes I have a BeBox around. I started looking at a Haiku port, you can find a bebox branch on github.
Not very far yet, The loader built at one point (I’ll have to rebase and fix some more merge conflicts), but GNU ld claims to know how to write PEF (which the boot rom wants) but actually just emits the section contents without any header. So that’s what I last started, fixing PEF support in GNU ld.
You can actually find some bootrom dumps around, at least last I searched. Also, some people (including me) started early BeBox support for QEMU but it’s been getting dust for a while. MAME (actually, MESS) has some BeBox support, but all it does is show the Be logo but wasn’t able to load anything when I tried.
