[Qemu-devel] [PATCH] Add args for quiet and prompt

[Cory Fields <FOSS@AtlasTechnologiesInc.com>]

Syntax is -boot [cad],prompt=x,quiet=x where x is [0,1,true,false]
Boot drive is mandatory
If prompt is set user will see "Press f12 for boot menu"
This behavior has changed, it is now off by default

If quiet is set user will see no normal text output from bios.
Errors will stil be displayed.
