IntroductionThe 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 − PCI UHCI USB controller and a virtual USB 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" 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. qemu-system-i386 dos.img -soundhw gus -parallel none Alternatively: qemu-system-i386 dos.img -device gus,irq=5 Or some other unclaimed IRQ. CS4231A is the chip used in Windows Sound System and GUSMAX products
