+<p class="Pp">The <code class="Nm">bochsfb</code> driver provides support for
+ graphics devices implementing the Bochs VBE DISPI interface, including the
+ Bochs reference VGA implementation, and the QEMU StdVGA device. It programs
+ the linear framebuffer through the DISPI registers and makes it available
+ through <a class="Xr">wsdisplay(4)</a> as a console or
+ <a class="Xr">wsfb(4)</a> compatible framebuffer.</p>
+<p class="Pp">When a memory-mapped DISPI bar with an EDID block is present,
+ <code class="Nm">bochsfb</code> uses the preferred mode reported by the
+ display. Devices without EDID support (such as virtio-vga) fall back to a
+ 1024x768 32-bit mode. If no MMIO bar is available, the driver accesses the
+ DISPI registers via the legacy VGA I/O ports.</p>
