Apparently there are some limitations on the C/H/S parameters you use for the disk that correspond with how UFS wants to format a new filesystem. I'm not sure what exactly those limitations are at this point, but, by adjusting a couple of the C/H/S settings when using format to set up the disk I was able to get it to work correctly. So, I now have Solaris 9 installed on qemu-system-sparc with OpenBIOS! I'll probably go back to Solaris 8 as that one has a free binary license while Solaris 9 is a commercial license, IIRC. I do own a Solaris 9 commercial license, but I like the free idea, better. Anyway, now I'm on to an issue with networking - I've used the following two qemu network parameter combinations: -net nic -net tap,ifname=tap0 -net nic -net user In the first instance, tap0 was configured on my Linux box and added to my bridge br0. In both cases the Solaris system is unable to obtain a DHCP address - the DHCP client times out. Not sure if I should be using a different parameter set, or if this is another area that needs some work either for OpenBIOS or qemu? -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

For whatever reason, the SUNW,m64B driver returned a failure at open - either some allocation failed or it decided it didn't like the hardware it found.

OpenBIOS PowerPC missing open firmware commands
by Alexander von Gluck July 20, 2011

July 20, 2011

Just a few things I noticed while hacking away at Haiku on PowerPC: The following OpenFirmware commands aren't implemented: erase-screen toggle-cursor The following paths are missing essential information: cpu node -> clock-frequency cpu node -> timebase-frequency cpu node -> bus-frequency Example: cd / cd cpus cd PowerPC,750@0 .properties These properties are present on real PowerPC hardware, but are set to 0 (or missing in the case of bus-frequency) on the qemu OpenBIOS. Thoughts? Thanks! -- Alex

The output being something like this. ok showstack ok " /pci/SUNW,m64B " open-dev 0 ok Is there anything wrong with this approach.

Look at the "reg" and "assigned-address" properties, and the semantics of "map-in". On SBus machines, the FCode of the SBus cards would created these properties indicating where the PIO space of video card would be, on PCI machines, the BARs will do this and be reflected in the "reg" and "assigned-address" properties.

fcode rom loading
by Bob Breuer July 14, 2011

July 14, 2011

I'm trying to get the sparc32 OpenBIOS to load an fcode rom, but it's not working. After byte-load, it reports out of memory. Here's the steps I'm using to setup a simple rom which just sets the device name to "QEMU,test", and then trying to run it: fd000000 1000 l! 00000020 1004 l! 12095145 1008 l! 4d552c74 100c l! 65737401 1010 l! 1412046e 1014 l! 616d6501 1018 l! 10000000 101c l! cd /iommu/sbus " /iommu/sbus" select-dev new-device 1000 1 byte-load Here, OpenBIOS will report out of memory.

Author: mcayland Date: Thu Jul 14 16:37:34 2011 New Revision: 1045 URL: http://tracker.coreboot.org/trac/openbios/changeset/1045 Log: Fix Fcode table initialisation on SPARC32. Increase the Forth machine memory to 128K (also requiring a corresponding increase in OFMEM to 384K) to allow enough space for the Fcode tables to be initialised, and hence allow Fcode to be executed under SPARC32.

Ah - on SPARCs, the video is not at a fixed address. The "display" device tree node will tell you what the physical address is (which varies from platform to platform) with the "reg" property, and you have to "map-in" that physical address to a virtual address.
