DMA/Refresh - Data Errors

Data was sent and retrieved OK but when compared differences were detected.

The most likely cause of this is a hardware (timing) incompatibility between the ISA or PCI card and the PC ISA or PCI bus. This incompatibility has been seen most often with older ISA cards and the more modern PCs that still have ISA slots, and with the earlier PCs that had PCI slots. Another reason would be the design of your PC motherboard is poor (this occurs surprisingly often).

Try disabling DMA in the Device Driver Settings.
