Hi Nick,
Thanks again for testing this. The issue with Solaris not detecting the disks is a known one - the following guide should point you in the right direction: http://virtuallyfun.blogspot.com/2010/10/formatting-disks-for-solaris.html
Also don't forget the "set scsi_options" part from Artyom's SPARC/QEMU howto here: http://tyom.blogspot.com/2009/12/solaris-under-qemu-how-to.html
I think it may actually be possible to come up with a patch for OpenBIOS so that the scsi_options change isn't required - let me know how you get on with the above links, and if it all seems to work I'll look at creating the patch for you.
ATB,
Mark.
Mark,
Is the information on the blogspot link available at another location (perhaps on this mailing list)? Where I work we have a fairly tight internet policy, so most blogs are inaccessible (both artyom's and the virtuallyfun one).
