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
