Yes, it uses the right rom.

Thats a good hint :)
Seems i used to compile qemu without "--audio-drv-list". Since "dsound" and
"fmod" drivers don't compile here (i likely miss some libs in my mingw), i used 
"sdl".
Now i can hear those two beeps with the image you suggested. Tho those are 
coming
thru my sound card and not the hosts pc speaker (even with "-soundhw pcspk", 
but maybe
that option means something different).
With INT 10h AH=0Eh i now can hear a beep too, but it doesn't stop and qemu 
somewhat freezes.

Unfortunatelly Windows Mail tends to do this and i failed to find an option to 
fix it.
