JSI Tip 3289. Device Manager Lists ATA-100 Device as using PIO?

When Microsoft added support for ATA-100 in Windows 2000, they failed to modify the user interface to reflect the fact that it uses UDMA.

This will probably be fixed in a future Service Pack.

NOTE: For other devices, see tip 2247 » How do I check/set DMA Transfer Mode in Windows 2000?

NOTE: You can ignore the incorrect display.
