First, the scenario.
New HP PC with Vista Home Premium. Could not get Flight Simulator 2004 to run. Continually showed "Out of Memory" error message. PC has 4 GB's of RAM and a 512 GB Nvidia 8500GT card. OEM Creative SB X-Fi Extreme Audio sound card.
After the 5th re-format/install, I gave up on Vista and installed XP PRO SP2 with all the appropriate drivers for the hardware. Flight Simulator ran like a champ. However, the BIOS would not recognize the sound card. No entry for Plug N'Play. Windows however, does see the card in Device Manager but lists it this way: Creative Audio Device (reserved)(inactive). I can't install the Creative driver as I get the message "Set Up does not recognize the appropriate hardware for the installtion" or something very close to that. I have disabled the onboard audio in the BIOS.
My questions are these. Is the BIOS programed to the OS? Because Vista was the original OS, is there a conflict with the newly installed XP in the BIOS? Just trying to find out why the BIOS won't recognize the sound card.
