Here's a patch file based on the latest snapshot that addresses everything up through #9, excluding #5 (which requires a tweak to qemu). It includes the patch for #2 written by Blue Swirl, which copies the entire contents of the ROM into RAM.
Thank you for your work, it would be great to get more OSes running on Qemu/OpenBIOS.
Just one comment: On my Sun4m machine (SS-5) the OBP properties for interrupt and counter reg nodes are as follows:
$ cat obio/interrupt@0,e00000/reg 00000000.00e00000.00000010.00000000.00e10000.00000010 $ cat obio/counter@0,d00000/reg 00000000.00d00000.00000010.00000000.00d10000.00000010
Your patch deviates from this. If you want to emulate a SS-10, it may be better to add it as a new sub-machine type to Qemu and OpenBIOS. I don't know how much SS-5 and SS-10 differ. For example, what is the MMU on SS-10, is it also Swift (SRMMU)?
