Hi Mark,
[adding the OpenBIOS mailing list, hoping to get some more feedback]
by the way, currently Jean Michel has to use the proprietary OBP. There seems to be a problem with loading the SunOS 4.x under OpenBIOS:
$ sparc-softmmu/qemu-system-sparc -L pc-bios -nographic -hda disk-solaris-1.1.2
Configuration device id QEMU version 1 machine id 32 CPUs: 1 x FMI,MB86904 UUID: 00000000-0000-0000-0000-000000000000 Welcome to OpenBIOS v1.0 built on Aug 19 2012 13:36 Type 'help' for detailed information Trying disk... Not a bootable ELF image Loading a.out image... Loaded 7680 bytes entry point is 0x4000 bootpath: /iommu/sbus/espdma/esp/sd@0,0
Jumping to entry point 00004000 for type 00000005... switching to new context: Unhandled Exception 0x00000007 PC = 0x00401a04 NPC = 0x00401a08 Stopping execution
Is the OpenBIOS guess correct and SunOS 4.x actually does have an a.out loader?
