| 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. |
| |
| 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\" SchΓΌtz. |
| |
| 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``) |
