 # Short answer -- do not enable this unless you know what you are

-# SeaBIOS integration is a work in progress. Before enabling this
-# option you must clone git://git.qemu.org/seabios.git/, possibly add
-# some development patches and then build it yourself before pointing
-# this variable to it (using an absolute path).
