[Qemu-devel] Disabling ISA bus?

[Qemu-devel] Disabling ISA bus?

[Leo Whitman]

Hi,

I was wondering if anyone had any insight as to whether it was possible 
to disable the ISA bus entirely inside QEMU.  If it is possible, does 
anyone know the best way to do this?  I spent time isolating the ISA 
peripherals, but noticed that the PIIX3 emulator and other devices tend 
to have interdependencies.  I was hoping there was an easy solution.

The reason is, with newer operating systems, PCI-only systems are 
possible (natively at least.)  It may be a nice option to add to the 
mix, and I'd be happy to do the work if anyone has any pointers.

Thank you in advance,

- Leo Whitman

The emulated chipset (Intel 440BX as i remember) has legacy devices.

Try to implement emulation of a modern chipset (southbridge at least) 
that does not require legacy devices and then you should be able to 
remove the ISA bus (of course, you need to implement USB emulation for 
HID devices at least, and implement it support in the QEMU's BIOS).

I see now.  I didn't even think about the HID devices, and the BIOS 
changes.  Thank you for the response,
