[OpenBIOS] RFC: change default SPARC boot order to "disk:a disk"

[Mark Cave-Ayland]

Hi all,

I've had a bug report off-list indicating that r1199 broke booting 
Solaris from hard disk. Some investigation shows that the simple reason 
is because the boot list in arch/sparc32/openbios.c is missing a slice 
letter, and so the boot device in romvec is set incorrectly.

As the disk device in OpenBIOS/QEMU is effectively modelled as 
sd(0,0,0), then I believe the correct solution should be this:


diff --git a/openbios-devel/arch/sparc32/openbios.c 
b/openbios-devel/arch/sparc32/openbios.c
index abdfe7c..6d1c3dc 100644
--- a/openbios-devel/arch/sparc32/openbios.c
+++ b/openbios-devel/arch/sparc32/openbios.c
@@ -887,7 +887,7 @@ arch_init( void )
                 push_str("floppy");
                 break;
         case 'c':
-               push_str("disk");
+               push_str("disk:a disk");
                 break;
         default:
         case 'd':


Unfortunately I only have a couple of SPARC disk images as my main test 
suite is ISO based, and so while it works for me (and the original 
reporter), I'm a bit nervous about just applying the change as-is.

Can anyone confirm that my understanding of Solaris slices is correct, 
and that this is indeed the correct solution to the problem?


Many thanks,

Mark.
