> Since Bochs 2.2 it is possible to use Cirrus SVGA graphics. The Cirrus device
supports both ISA and PCI depending on the <TT
CLASS="FILENAME"
>bochsrc</TT
> settings.
If PCI is disabled or the Cirrus card is not assigned to a PCI slot, it appears
as a CL-GD5430 ISA with 2MB VRAM. If you assign the Cirrus card to a PCI slot,
it appears as a CL-GD5446 PCI with 4MB VRAM.

> In order to use Cirrus SVGA, you need to compile Bochs using the <CODE
CLASS="OPTION"
>--enable-clgd54xx</CODE
>
option and enable it in your <TT
CLASS="FILENAME"
>bochsrc</TT
> by setting the
<A
HREF="x1387.html#BOCHSOPT-VGA"
>vga option</A
> to <TT
CLASS="PARAMETER"
><I
>cirrus</I
></TT
>.
Finally, you need to use the Cirrus version of the

as <A

applications to correctly detect Cirrus support.
