Hi,
Current versions of Qemu (with the attached PCI patch) and OpenBIOS get this far: OpenBIOS for Sparc64 boot arg = 0x0
00000000-08000000 RAM 128 MB forth started. initializing memory...done Initializing PCI devices... 0:0.0 - 108e:a000 - /pci/pci108e,a000 - host 0:1.0 - 108e:5000 - /pci/pci108e,5000 - pci 0:1.1 - 108e:5000 - /pci/pci108e,5000 - pci 0:2.0 - 1013:b8 - /pci/pci1013,b8 - display 0:3.0 - 10ec:8029 - /pci/pci10ec,8029 - ethernet 0:4.0 - 1095:646 - /pci/pci1095,646 - ide floppy_init FDC is a S82078B floppy_reset floppy_motor_off SENSEI 20 00 status = 80, reply_buffer= 20 0 fdc_specify FD_SPECIFY(c1, 11) set_drive status = 80, new_dor = 10 floppy_recalibrate fdc_state.version = 0062 invalid nvram partition length nvram error detected, zapping pram falling off...

For some reason some C functions do not get called from Forth, so the booting does not start and execution falls off the main function.
The PCI patch is just a quick hack to get PCI probing succeed, I won't commit it in yet.
