Yes,

in the obp, change the definition of the variable "output-device" to the
address of the internal/onboard graphics circuit.

the obp manual can be found on docs.sun.com

you will have to ascertain the hardware address of the onboard graphics
and either create an alias for the hardware address or use the hardware
address itself
change the variable "output-device" to the aliase or the hardware address.

the obp manual give the instructions for creating and using the alias.

i haven't done this in years, so i pull out the manual and follow the
instructions.

the process of changing the variable is fairly simple; the hardware address
has to be copied correctly.
