DIGITAL-LOGIC AG 4.1.6. Geode LX800 Manual V1.1C Driver, Software & BIOS Information Windows XP 2nd IDE bug fix Most PC-AT chipsets contain a dual IDE controller. The AMD Geode™ CS5536 and CS5535 companion devices contain only a single IDE controller. These companion devices use the same out-of-box Windows® XP IDE driver as other compatible chipsets. This may present a problem, since the driver will assume a dual controller is present.
