To put in another graphics board you must first disable your present board. To
do this you remove a 74LS00 chip located on the bottom middle of the graphics
board. It is above where the +5 volts and ground wire connect. In newer
machines it is in a socket on older ones it is soldered in. NOTE this will
void your warranty if you do it yourself! After removing the chip then pins 7&6
must be jumpered together and 3,8,11,14 must all be tied together. We got
this fix directly from AT&T. We just bought 300 of these units and some will be
modified.
All the usual disclaimers, ect...
