Thanks for the info - I opened the IDE ATA/ATAPI Controllers: Intel 82801FB Altra Storage Controllers - 2652, 266F, 2 Primary IDE Channels and a Secondary Channel. All controllers are "working properly" - also attempts at updating did not succeed - no need for upgrades. Am I missing a driver? Is this alert bogus?

> If you open the Device Manager (windows+pause/break > Hardware > Device Manager) and select the entry for IDE ATA/Atapi and select the Primary IDE > Advanced Settings, does it say the "current transfer mode" is DMA or PIO?

If it says PIO, first ensure "Use DMA if Available” is selected, then select the driver tab and uninstall the driver and reboot. Then check again.

>> the important thing here is the "Current Transfer Mode" must NOT be PIO -- regardless of whether the device is "working properly".

You might also check in the BIOS and make sure DMA is enabled for all the channels. :)
