QEMU SYSTEM REQUIREMENTS WINDOWS

Qemu-system-x86_64 dos.img -device gus,irq=5ĬS4231A is the chip used in Windows Sound System and GUSMAX products Qemu-system-x86_64 dos.img -device gus -parallel none Must be told to not have parallel ports to have working GUS. Note that, by default, GUS shares IRQ(7) with parallel ports and so QEMU QEMU uses YM3812 emulation by Tatsuyuki Satoh. QEMU uses the PC BIOS from the Seabios project and the Plex86/Bochs LGPL

PCI UHCI, OHCI, EHCI or XHCI USB controller and a virtual USB-1.1.

Adlib (OPL2) - Yamaha YM3812 compatible chip.

Intel HD Audio Controller and HDA codec.
