Build the appropriate ROM image:

  cd gpxe/src
  make bin/10ec8029.rom  # for ns8390 10ec:8029

=== Running QEMU ===
The **-option-rom** command-line option tells QEMU to use the gPXE ROM:

  qemu -option-rom /path/to/10ec8029.rom /dev/null

This example runs a default VM with no disks and allows you to press Ctrl+B to enter gPXE.
