   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
  39SMP is supported with up to 255 CPUs.

  41QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL
  42VGA BIOS.
  43
  44QEMU uses YM3812 emulation by Tatsuyuki Satoh.
  45
  46QEMU uses GUS emulation (GUSEMU32 http://www.deinmeister.de/gusemu/) by
  47Tibor \"TS\" Schütz.
  48
  49Note that, by default, GUS shares IRQ(7) with parallel ports and so QEMU
  50must be told to not have parallel ports to have working GUS.
  51
  52.. parsed-literal::
  53
  54   |qemu_system_x86| dos.img -device gus -parallel none
  55
  56Alternatively:
  57
  58.. parsed-literal::
  59
  60   |qemu_system_x86| dos.img -device gus,irq=5
  61
  62Or some other unclaimed IRQ.
  63
  64CS4231A is the chip used in Windows Sound System and GUSMAX products
  65
  66The PC speaker audio device can be configured using the pcspk-audiodev
  67machine property, i.e.
  68
  69.. parsed-literal::
  70
  71   |qemu_system_x86| some.img \
  72   -audiodev <backend>,id=<name> \
  73   -machine pcspk-audiodev=<name>
