| 1 | The QEMU PC System emulator simulates the following peripherals: |
| 2 | |
| 3 | - i440FX host PCI bridge and PIIX3 PCI to ISA bridge |
| 4 | |
| 5 | - Cirrus CLGD 5446 PCI VGA card or dummy VGA card with Bochs VESA |
| 6 | extensions (hardware level, including all non standard modes). |
| 7 | |
| 8 | - PS/2 mouse and keyboard |
| 9 | |
| 10 | - 2 PCI IDE interfaces with hard disk and CD-ROM support |
| 11 | |
| 12 | - Floppy disk |
| 13 | |
| 14 | - PCI and ISA network adapters |
| 15 | |
| 16 | - Serial ports |
| 17 | |
| 18 | - IPMI BMC, either and internal or external one |
| 19 | |
| 20 | - Creative SoundBlaster 16 sound card |
| 21 | |
| 22 | - ENSONIQ AudioPCI ES1370 sound card |
| 23 | |
| 24 | - Intel 82801AA AC97 Audio compatible sound card |
| 25 | |
| 26 | - Intel HD Audio Controller and HDA codec |
| 27 | |
| 28 | - Adlib (OPL2) - Yamaha YM3812 compatible chip |
| 29 | |
| 30 | - Gravis Ultrasound GF1 sound card |
| 31 | |
| 32 | - CS4231A compatible sound card |
| 33 | |
| 34 | - PC speaker |
| 35 | |
| 36 | - PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1 |
| 37 | hub. |
| 38 | |
| 39 | SMP is supported with a large number of virtual CPUs (upper limit is |
| 40 | configuration dependent). |
| 41 | |
| 42 | QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL |
| 43 | VGA BIOS. |
| 44 | |
| 45 | QEMU uses YM3812 emulation by Tatsuyuki Satoh. |
| 46 | |
| 47 | QEMU uses GUS emulation (GUSEMU32 http://www.deinmeister.de/gusemu/) by |
| 48 | Tibor \"TS\" Schütz. |
| 49 | |
| 50 | Note that, by default, GUS shares IRQ(7) with parallel ports and so QEMU |
| 51 | must be told to not have parallel ports to have working GUS. |
| 52 | |
| 53 | .. parsed-literal:: |
| 54 | |
| 55 | |qemu_system_x86| dos.img -device gus -parallel none |
| 56 | |
| 57 | Alternatively: |
| 58 | |
| 59 | .. parsed-literal:: |
| 60 | |
| 61 | |qemu_system_x86| dos.img -device gus,irq=5 |
| 62 | |
| 63 | Or some other unclaimed IRQ. |
| 64 | |
| 65 | CS4231A is the chip used in Windows Sound System and GUSMAX products |
| 66 | |
| 67 | The PC speaker audio device can be configured using the pcspk-audiodev |
| 68 | machine property, i.e. |
| 69 | |
| 70 | .. parsed-literal:: |
| 71 | |
| 72 | |qemu_system_x86| some.img \ |
| 73 | -audiodev <backend>,id=<name> \ |
| 74 | -machine pcspk-audiodev=<name> |
| 75 | |
| 76 | Machine-specific options |
| 77 | ~~~~~~~~~~~~~~~~~~~~~~~~ |
| 78 | |
| 79 | It supports the following machine-specific options: |
| 80 | |
| 81 | - ``x-south-bridge=PIIX3|piix4-isa`` (Experimental option to select a particular |
| 82 | south bridge. Default: ``PIIX3``) |
