+@c man begin DESCRIPTION
+
+The QEMU PC System emulator simulates the following peripherals:
+
+@itemize @minus

+i440FX host PCI bridge and PIIX3 PCI to ISA bridge
+@item
+Cirrus CLGD 5446 PCI VGA card or dummy VGA card with Bochs VESA
+extensions (hardware level, including all non standard modes).
+@item
+PS/2 mouse and keyboard
+@item
+2 PCI IDE interfaces with hard disk and CD-ROM support
+@item
+Floppy disk
+@item
+PCI and ISA network adapters
+@item
+Serial ports
+@item
+IPMI BMC, either and internal or external one
+@item
+Creative SoundBlaster 16 sound card
+@item
+ENSONIQ AudioPCI ES1370 sound card
+@item
+Intel 82801AA AC97 Audio compatible sound card
+@item
+Intel HD Audio Controller and HDA codec
+@item
+Adlib (OPL2) - Yamaha YM3812 compatible chip
+@item
+Gravis Ultrasound GF1 sound card

+CS4231A compatible sound card
+@item
+PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1 hub.
+@end itemize
+
+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 @url{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.
+
+@example
+@value{qemu_system_x86} dos.img -soundhw gus -parallel none
+@end example
+
+Alternatively:
+@example
+@value{qemu_system_x86} dos.img -device gus,irq=5
+@end example
+
+Or some other unclaimed IRQ.
+
+CS4231A is the chip used in Windows Sound System and GUSMAX products

+@subsection OS requirements
+
+On x86_64 hosts, the default set of CPU features enabled by the KVM accelerator
+require the host to be running Linux v4.5 or newer.  Red Hat Enterprise Linux
+7 is also supported, since the required functionality was backported.
