Silicon Graphics 320/540 Visual Workstation are two PC models produced by SGI which are not IBM-compatible PCs. They are known for using ARC firmware, just like in NT for RISC platforms, with a graphical interface available before the actual OS is booted.
ReactOS is not ported to ARC-based SGI Visual Workstation series yet.
Both 320 and 540 use Pentium compatible CPUs so they could run ReactOS once it's ported.
SGI 320/540 use a proprietary video adapter based on Cobalt chipset. Also it has a firmware that is completely different from a Standard PC BIOS, so a new HAL should be created. Otherwise its hardware is similar to IBM PC, such as PCI bus.
In Windows 2000 there is one known HAL for this platform:

There are no known emulators of this platform.
