Without further investigation of the board, noone but Gigabyte can say how it's supposed to be used. > As Peter mentioned LPC is used on this board.

Yes, but the question is what, if anything, controls the second INIT#. The patent suggests a timer circuit, but your measurements show that perhaps the timer circuit is just not there on production boards. One solution is of course to not connect the two INIT# to the pads on the board, but to a separate switch circuit. Desoldering a single PLCC pin is not impossible with a little care. //Peter -- linuxbios mailing list [EMAIL PROTECTED] http://www.linuxbios.org/mailman/listinfo/linuxbios
