When you disable shared memory did you install another network card first. If not that is you problem, you have no video at all. If it is your intention to install a separate video card you should install that first before you disable shared memory.

The easiest way to clear the CMOS is to locate the Clear CMOS jumpers on the motherboard and move the jumpers to the clear position for a second or two with the power removed. Return he jumpers to its original position and reboot.

Removing the battery doesn't always work as it can take some time for the CMOS memory to decay and can leave it in an unknown state. Using the jumpers uses the power of the CMOS battery to clear the memory completely leaving no doubt as to what state it is in.
