FYI: Restoring DMA access on an "IDE ATA/ATAPI controller"

The main harddrive on my computer (running Windows-XP Pro, now SP3)
had slipped to PIO mode. Microsoft support information at
http://support.microsoft.com/kb/817472 ("IDE ATA and ATAPI disks use
PIO mode after multiple time-out or CRC errors occur") did not give me
much joy. A google search took me to http://winhlp.com/node/10 and
then on to the vbscript, http://winhlp.com/tools/resetdma.vbs.
I ran the vbscript -- with a little trepidation, but my hard disk,
Seagate ATA 160GB, was already agonizingly slow. On reboot I found
that Ultra DMA Mode 5 has been restored, and my disk is shutting down,
rebooting, hibernating, resuming, etc. at near normal speed.

I thought the info would be of use to others.
