Additionally, it would be worth trying to pass the = GPU ROM to the guest. Therefore, you have to extract it on a Linux or Windows system, e.g. http://etherboot.org/wiki/romdumping, and then make use of the= rom parameter from passthru. --=20 You are receiving this mail because: You are the assignee for the bug.=
