- 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 a large number of virtual CPUs (upper limit is
- configuration dependent).
- 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``)
