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.

solaris 8 on sparc, webstart launcher crashing
by Brian Vandenberg 31 May '11

31 May '11

Greetings, I'm unsure whether the issue I'm running into is related to OpenBios, qemu, something buggy in this solaris distribution, or some combination thereof. Feel free to redirect me as appropriate. I'm able to install Solaris 8 (02/04) from the "Solaris 8 Software disk 1" disk. I see a few different behaviors depending on what I try: 1) boot from disk0:a without any special options: After specifying a root password, it says "Starting Web Start Launcher in Command Line Mode" and shortly thereafter says "The Webstart launcher has terminated unexpectedly." with no further details, except to say the machine will reboot after pressing enter. 2) Do the same thing, but with -v: The result doesn't seem predictable. Sometimes it just hangs after the "Starting ..." line, other times it dies with a variety of errors. I'll try to summarize below: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Starting Web Start Launcher in Command Line Mode.

I originally formatted it as a "SUN2.9G" in the format utility, but I let it autoconfigure the partitions. partition '0' is root (1.18G), '1' is swap (149m), '2' is backup (2.71g), and '7' is home (1.39g). There's overlap in the cylinder ranges specified and the total size between those partitions is larger than 3g ... but, I have no idea whether that's just a Sun-ism, or whether I need to partition manually. I don't think it's my partitions, though. The 'vol' directory doesn't exist in my root before I try to get the webstart stuff to run, so I think it's creating that directory and trying to mount an image to it. Additionally, I'm starting qemu with: ./qemu_system_sparc -nographic -bios /imgpath/openbios-sparc32_artyom.bin -hda /imgpath/solaris2.8-img3.qcow2 -m 256 -net nic -net user -cdrom /imgpath/solaris2.8/software_1of2.iso prom-env 'auto-boot?=false' -snapshot If anyone has a good idea, I'm all ears ...

Getting Closer With Booting AIX? I Would Like to Help Please.

Re: [OpenBIOS] [Qemu-devel] [PATCH 01/27] Clean up PowerPC SLB handling code
by Andreas Färber 20 May '11

20 May '11

QEMU HEAD still uses a 32-bit binary for both 32-bit and 64-bit. That one uses mtsrin so will need the compatibility, it seemed affected, too. OpenBIOS SVN HEAD (blob) uses slb* as linked to. We're in the preparation of 1.1 and I need to test it before we can update the QEMU binary. ;) Sorry for top-posting, Android sucks.
