Once complete, the Add Hardware Wizard will prompt again to load driver support for a "Promise SATA Console Processor Device". You won’t be able to load a driver for this device so just ignore it. Cancel the Add Hardware Wizard.

After this is done, the Device Manager should show two new listings. One should be under "SCSI and RAID controllers" and should be listed as "Win(x) Maxtor SATA/150 PCI Card". The other should be under "Other Devices" with a question mark next to it. This is the "Promise SATA Console Processor Device". Again, ignore this device. A driver cannot be loaded for it.

Once a SATA or PATA drive is connected to the card, the "Promise SATA Console SCSI Processor Device" listing will go away. If all drives are disconnected from the card, the Add Hardware Wizard will reappear when the system is booted.

Additional Information:

The Promise SATA150 TX2plus drivers will work with the Maxtor SATA/150 controller cards since they are based on the same hardware but are not supported by Maxtor. They do not address this issue but have various compatibility fixes:
