Just installed a new "PCW TX Pro AT W/Video 4MB and Sound" from micro x-press with AMI Bios. Using known good 166 CPU and tested 32 mb SIMMs. Triple checked all jumpers and connections and fired it up - Get nothing. No post beep. Slight flicker on monitor w/ gray screen. Keyboard lights flash at turn on, no floppy light, HD spins up and light shows for a while, then goes out. Anyone with experience with this board or help in general with MB installations?
