Comment 4 for bug 1260555

Ah, I hadn't tried -nographic. However, my general point still stands: whether you run this on MacOS or Linux, you get the same behaviour.

Experimenting I see that all that's happening here is that '-nographic' gives you a serial console, which the ROM outputs to. You can also specify that with '-serial stdio' instead, in which case you get ROM output to the terminal and a blank display. So the two parts of this bug are:

(1) no graphics output with this ROM
(2) cocoa UI doesn't properly show a black window if there is no graphics output from the guest

I have some patches which fix (2).

(If you have a bug which is a general QEMU emulation bug, it's a really bad idea to describe it using phrases like"on Cocoa" or "on MacOS" which suggest that it's a MacOS host specific bug, because this will mean that it will get ignored by almost all the developers, most of whom use Linux. If you have access to a suitable machine it's definitely helpful to try reproducing on a Linux box before reporting a bug. If you've only been able to test on Mac you should say so somewhere in the bug report, though.)
