Actually not, there are no CE or CS signals here. But don't use Vcc, use INIT# instead. We just need to learn how it looks during boot and how it is connected on the two chips, then the U10 pads can be used to fit a socket and T1/T2 pads used for the switching circuitry. > No idea how hard or easy it is to desolder single pins instead of > the complete chip. It is a good idea though! Too hard, better just use the ready made PLCC pads for a socket. :) //Peter -- linuxbios mailing list [email protected] http://www.linuxbios.org/mailman/listinfo/linuxbios
