Re: [Qemu-devel] SPARC patch for OS X (big endian machines)

2005-11-01 Thread Jose Renau 


 The new patch is clearly nicer (I did not know the interface), it 
solved

the bug that I reported, but It still crashes booting Linux.

 Hopefully one of my students will take a look.

I made a more generic patch. Tell me if it still works...

Pretty cool.
I can confirm this for SPARC hosts , too (also MSB).

Hey, be aware that the SPARConSPARC case finally works with your patch :)
Even in SDL/gui mode, not just with -nographic.

Thank you!
