Mac OS 9.2 fails to boot with a popup saying :
Sorry, a system error occured.
"Sound Manager"
address error
To temporarily turn off extensions, restart and
hold down the shift key
Darwin and Mac OSX look OK.
My guess would be that MacOS 9.2 is trying to access the sound chip registers
which isn't implemented in QEMU for the moment (I have a separate screamer
branch available, but it's not ready for primetime yet). In theory they
shouldn't be accessed at all because the sound device isn't present in the
OpenBIOS device tree, but this is all fairly old stuff.
Does implementing the sound registers using a dummy device help at all?
