I'm trying to add an AGP Radeon LE video card to my SD11 motherboarded system and it won't work. I removed all existing drivers from previous card (3DBlasterSav4)and the card ,in safe mode, then I made the AGP card primary in the BIOS and it won't work. Actually when I try to boot up the computer it's almost like the slot is broken because the computer won't even boot or send any kind of message to the monitor. In other words, the use of the AGP slot is causing the system to hang before it even tries to boot up. I have checked the card in another machine and it works fine. I have a fairly late BIOS (NC608) and the rest of the system runs great. As a matter of fact, I just did a clean reinstall and it runs perfectly except for this. Any helpful ideas would be appreciated, Thanks
