so i brought a hp hd2600 mobility off of eBay, then i replaced the existing hd2400 with that. problems below. it can boot OSX, but i can ONLY operate the computer using splashtop(display streaming to my iPad). OSX does not recognize the new card and graphics are laggy. internal display and dvi port have no signal. when i set startup disk to windows, it does not work period. not even splashtop. (black screen all the way) the graphics card flashing software(zues) doesn’t flash under OSX because it did not detect any graphics card. so the only way to flash this card is under windows which the mac does not boot. any ideas?
You have a very tricked out system here At this point I think you’ll need to get a 2400 XT (new or used) to make sure the system is able to even see it. Replacing is for the better 2600 Pro should be doable (Others have done it). It’s likely the current OS on your HD is missing the driver for it. Do you have the recovery CD/DVD and an optical drive which you can boot the system up with?
