You probably won't believe this but I don't have that option in BIOS. This is what I have under Boot options:
Silent Boot
Intel (R) Rapid Bios Boot
After Power Failure
Wake on MOdem RIng
Wake on LAN
Wake on PMC
1st Boot Device
2nd Boot Device
3rd Boot Device
4th Boot Device
IDE Drive Configuration
That is all I have. Even Gateway acknowledged that I didn't have any options in BIOS to disable the integrated card. That's why it is so frustrating that I cannot do it (ie. it doesn't work) under the device manager. Any suggestions?
