   5 Use the executable @file{qemu-system-sparc64} to simulate a Sun4u
   6 (UltraSPARC PC-like machine), Sun4v (T1 PC-like machine), or generic
   7 Niagara (T1) machine. The Sun4u emulator is mostly complete, being
   8 able to run Linux, NetBSD and OpenBSD in headless (-nographic) mode. The
   9 Sun4v emulator is still a work in progress.

  11 The Niagara T1 emulator makes use of firmware and OS binaries supplied in the S10image/ directory
  12 of the OpenSPARC T1 project @url{http://download.oracle.com/technetwork/systems/opensparc/OpenSPARCT1_Arch.1.5.tar.bz2}
  13 and is able to boot the disk.s10hw2 Solaris image.
  14 @example
  15 qemu-system-sparc64 -M niagara -L /path-to/S10image/ \
  16                     -nographic -m 256 \
  17                     -drive if=pflash,readonly=on,file=/S10image/disk.s10hw2
