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.
