You will have to change a jumper setting (located in the back left-hand corner at the end of the last pci slot). It has two settings, one for Mac power supply (should be the setting to the left) and one for "PS2" (standard atx) supply to the right. Make sure you have it set to the "PS2" setting for the atx, and try powering it one. Also be sure that all items are securely seated (pci cards, personality card, rom, ram, cpu, voltage regulator, and cables). Be sure that you have the right setting for the cpu/bus speed; if it's out of the range the cpu or logic board can handle it won't boot. All else failing, use a pen-light to visually inspect the board. You might be able to see the damage. Hamlin -- G-List is sponsored by <http://lowendmac.com/> and...
