hehe.. Which DELL PowerEdge? :) 2650? 1750? 400SC? 1500SC? :)
In any case, I image that your system is using a small portion of system memory to emulate video RAM, and it's quite possible that Blitz can't tell the difference. 2 megs of RAM is barely enough to even SET the screen-res to 800x600 let alone loading any images, so video RAM emulation is almost a certainty - hence why the results are shown incorrectly.
