DOESN'T WORK
Acer Veriton with onboard video (PCIE AVGA 5000)
No offense, but I'm a bit skeptical of the premise of this thread. There should be no reason why your new graphics card (or any other PCIE graphics card) shouldn't work with your system. There's nothing really different about the graphics card hardware, and as the system has a PCIE x16 slot, it should work with a fairly basic ATi Radeon HD. Systems without support for external graphics cards will, more often than not, omit the PCIE connector entirely from the board.
The fact that you actually got a screen with a blinking cursor would tend to imply that the system is still trying to use the on-board video for whatever reason. One thing that's a bit wonky on some of these MB's (my C2D MB included) is the PCIE x1 support (the tiny card slot next to the PCIE x16.) On my system, I needed to change jumpers to alter the speed of the PCIE bus, which effectively disables the x1 slot
and the internal graphics. If you have something in that x1 slot, it may be effectively locking the bus at the x1 speed. Just something to check for. Of course, you would also need to tell the BIOS to use the PCIE graphics card. Documentation for your MB is woefully sparse, but I was able to ascertain that these jumpers don't exist on your MB, but there is support for the external graphics in the BIOS. So it's possible that any switching of the bus speed is automatic and may depend on whether a monitor is attached to the internal graphics connector at boot time, or whether the x1 slot is being used.
Finally, it can have something to do with having the correct monitor attached to the correct output at boot time. Any adapters from one type of connection to another in the mix, could make the card think there is no monitor attached, or the card may just not support the use of them. I.e. it's an extra variable that should be removed for troubleshooting. The other possibility is that the video card might just be defective. If you have another system, a quick card swap and a verification of the basic BIOS screen display would probably be a good first step to verify it isn't the video card at fault.
Take this info, or leave it. Maybe someone else will find it to be of value. I'd just hate to see you doing this again with a new system which might end up with similar issues needing to be addressed. As for the "malarky" of installation and configuration, it's just part and parcel of the upgrade process, particularly when dealing with specialized stuff like this. When I first set up my old system with the AGP version of your card, I too recall thinking "why is this such a pain? I thought it would just work". For some it might have, but when the situation includes a bunch of custom refresh rates, different 15kz monitors with different capabilities, mixing different monitors with different scan frequencies on the same card, etc., you soon realize that it can't be "plug and play" for everyone, and accept that there will be some unpleasantries involved in getting things to work the way you want. As a side note, the information on Calamity's site is daunting at first, but in reality, the process went no better or worse than I experienced with the "plug and play" solution
