This is getting confusing... :) On the sc1200 and and GX1, the ACB bus is accessed through ISA ports. There is no ISA on the cs5535/cs5536 companion chips (accompanying the GX and LX processors), and the ACB is accessed through PCI. All the platforms have LPC, but that really doesn't matter for the purposes of this discussion. The silicon block that implements the ACB has been generally unchanged over the last 6 or 7 years, so the same driver should support any of the platforms, assuming one can invoke the magic spells to get at the hardware. Jean and I have been concentrating most of our effort on getting the GX and LX to work through PCI, and really haven't concentrated our efforts on the older processors. Thats not to say it won't work, but its probably not plug and play.
