*******************************************************************

This README file is provided the information how to know the VIA 
PCI IDE Device Driver is running on the Linux Operation system, 
how to enable bus master function, and to adjust the DMA modes.

When the Linux OS boot up, if you see a line of message like the 
below one, then the VIA IDE controller is found.

	 VP_IDE: IDE controller on PCI BUS 00 dev 39

After login the system, you can use the 'hdparm' command to enable
DMA or disable DMA function.

Example: We takes the primary master hard disk as an example.

   Enable DMA function:
         # hdparm -d1 /dev/hda

   Disable DMA function:
         # hdparm -d0 /dev/hda

When the driver is running in DMA mode, you can change the DMA modes
as you like.

Example:
    
   Set Ultra DMA mode 2:
         # hdparm -X66 /dev/hda

   Set Multiword DMA mode 2:
         # hdparm -X34 /dev/hda

Note: The 'hdparm' command can also apply to CD-ROM drive.

To see more about the 'hdparm' command, you can type 'man hdparm'
command to see the manual pages of 'hdparm' command.
