I have an IBM Aptiva 2140-L31 with an onboard Trident 3D Image 975 chip mounted on the motherboard running WIN 98. The problem is I have bought a Velocity 4400 card and can't get it to work. I contacted STB and they said the problem was IBM's and IBM said it was STB. IBM said the on board card was self disabling and that their are not any jumpers to disable it. When I install the card the computer won't even boot up so I can't really do anything with the settings. STB said the on board card needs to be completely disabled to install the 4400. I tried removing the adapter from the device manager but still had the same results. Any help to this question would be greatly appreacited!
