Digging old bugs, I found this problem.

Maybe this patch helps? I can't test it here (can't get display to 16 bit 
somehow).

Seems like it works, booting aurora-2.0-sparc-disc1.iso gives me the
penguin at least.  Then it hangs and burns CPU as usual.

So early? I get to 'Running anaconda..' etc. Before AIO, install almost 
finished.

It still cannot decide on console device; linux console=/dev/tty0 works fine

Now I see, I'm using the current SVN version (82) of OpenBIOS, not Qemu's. 
Console selection works fine in the current version.

I found "console=tty0" works a little better, thanks for the hint.

Specifying the console allows aurora to get farther, even starting X.
Mouse doesn't seem to work though. ;0)

Gentoo 2004.0 shows me a mangled penguin, but otherwise boots.

Thanx, that seems to fix the 16 bit display problem. (I just had to set
	DefaultDepth 16
in Section "Screen" in xorg.conf to test it...)

 Fabrice, please apply. :)

 thanx + cheers,

Mouse should work with Igor Kovalenko's patch, which I resent some days ago.

But I can't get to X with aurora-2.0, it just hangs much earlier.

It must be hanging while probing for sound modules, try adding 'blacklist
snd-sun-cs4231' to /etc/modules.d/blacklist

This patch should fix hanging, unless some program waits until playback is 
finished.

Implementing full audio support for CS4231 would not be too difficult. Is 
this chip used anywhere else? The data sheet mentions some ISA card and 
Windows 3.1.

The "Windows Sound System" cards apparently used it.
