[Qemu-devel] [Bug 1588328] Re: Qemu 2.6 Solaris 9 Sparc Segmentation Fault

[Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>]

If you use OpenBIOS then you don't explicitly have to set scsi-options
since the value can be overridden via the device tree which is exactly
what OpenBIOS does.

Interestingly enough it seems that the default bootloader for Solaris 9
is installed in the slice rather than the root of the disk as per my
Solaris 8 installation. Fortunately you can manually boot Solaris 9 from
the slice by entering "boot disk:d" at the Forth prompt.

Based upon this it probably makes sense to add "disk:d" to the bootpath
used by OpenBIOS - I'll send a patch through to the OpenBIOS mailing
list shortly.

Title:
  Qemu 2.6 Solaris 9 Sparc Segmentation Fault

Status in QEMU:
  Fix Committed

Bug description:
  Hi,
  I tried the following command to boot Solaris 9 sparc:
  qemu-system-sparc -nographic -boot d -hda ./Spark9.disk -m 256 -cdrom sol-9-905hw-ga-sparc-dvd.iso -serial telnet:0.0.0.0:3000,server 

  It seems there are a few Segmentation Faults, one from the starting of
  the boot. Another at the beginning of the commandline installation.
