Re: [Qemu-devel] Solaris SPARC guest on QEMU

Laurent,

   The error message I get is this:

address@hidden qemu01]$ qemu-system-sparc -debug -nographic  -m 256 -hda

bootblk: can't find the boot program

  From this I gather that:

 Openbios understand the solaris disk label on the cdrom, since it can load the 
bootblk on cdrom:d and start it.

 Bootblk is loaded, but cannot read the second stage, that from what I could 
gather the second stage should be on cdrom:e, inside a ufs filesystem.

  Bootblk sources are available on OpenSolaris 10, but this version no longer 
has support for the older 32 bits servers, and it is writen in Forth. (up to 
now I could not make anything usefull from the sources, sigh).


Best Regards,
Luis
