I have installed X3 before without too much trouble before

(emphasis on the wink!!), but this one gets me. When I power up the xbox, instead of a nice, assuring, glowing blue light, I get no light for about 5 seconds on the X3 external switch, then it turns red and boots up to the M$ dash. But if I power it down and back up it boots up modded. It seems as when I leave the xbox off for a while OR drain the power ( disconnect A/C and hit power) and try to power it up it has the same lag. I have checked the voltages at the LPT and they seem good. If I unplug the X3 from the LPT it boots up fine. I've also tried re-flashing the bios, but to no avail. Any Ideas?
BTW it is a ver. 1.1 w/X3 pin header install.
Thanks a mil,
