The QEMU PC System emulator simulates the following peripherals:
|
|
|
|
- i440FX host PCI bridge and PIIX3 PCI to ISA bridge
|
|
|
|
- Cirrus CLGD 5446 PCI VGA card or dummy VGA card with Bochs VESA
|
|
extensions (hardware level, including all non standard modes).
|
|
|
|
- PS/2 mouse and keyboard
|
|
|
|
- 2 PCI IDE interfaces with hard disk and CD-ROM support
|
|
|
|
- Floppy disk
|
|
|
|
- PCI and ISA network adapters
|
|
|
|
- Serial ports
|
|
|
|
- IPMI BMC, either and internal or external one
|
|
|
|
- Creative SoundBlaster 16 sound card
|
|
|
|
- ENSONIQ AudioPCI ES1370 sound card
|
|
|
|
- Intel 82801AA AC97 Audio compatible sound card
|
|
|
|
- Intel HD Audio Controller and HDA codec
|
|
|
|
- Adlib (OPL2) - Yamaha YM3812 compatible chip
|
|
|
|
- Gravis Ultrasound GF1 sound card
|
|
|
|
- CS4231A compatible sound card
|
|
|
|
- PC speaker
|
|
|
|
- PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1
|
|
hub.
|
|
|
|
SMP is supported with up to 255 CPUs (and 4096 CPUs for PC Q35 machine).
|
|
|
|
QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL
|
|
VGA BIOS.
|
|
|
|
QEMU uses YM3812 emulation by Tatsuyuki Satoh.
|
|
|
|
QEMU uses GUS emulation (GUSEMU32 http://www.deinmeister.de/gusemu/) by
|
|
Tibor \"TS\" Schütz.
|
|
|
|
Note that, by default, GUS shares IRQ(7) with parallel ports and so QEMU
|
|
must be told to not have parallel ports to have working GUS.
|
|
|
|
.. parsed-literal::
|
|
|
|
|qemu_system_x86| dos.img -device gus -parallel none
|
|
|
|
Alternatively:
|
|
|
|
.. parsed-literal::
|
|
|
|
|qemu_system_x86| dos.img -device gus,irq=5
|
|
|
|
Or some other unclaimed IRQ.
|
|
|
|
CS4231A is the chip used in Windows Sound System and GUSMAX products
|
|
|
|
The PC speaker audio device can be configured using the pcspk-audiodev
|
|
machine property, i.e.
|
|
|
|
.. parsed-literal::
|
|
|
|
|qemu_system_x86| some.img \
|
|
-audiodev <backend>,id=<name> \
|
|
-machine pcspk-audiodev=<name>

Machine-specific options
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
It supports the following machine-specific options:
|
|
|
|
- ``x-south-bridge=PIIX3|piix4-isa`` (Experimental option to select a particular
|
|
south bridge. Default: ``PIIX3``)
