WindowsXP SP3 modification program for the DP25
Some models of the DP25 do not support WindowsXP SP3(When using DP25 (illustration 1.) with WindowsXP Professional (32bit) SP3, this modification program is required.). If you want to use such DP25 with WindowsXP, you must downgrade your IEEE1394 device driver to an older version. This modification program will change the IEEE1394 device driver updated by WindowsXP SP3 to an older version.

If you change the IEEE1394 device driver using this modification program, some unexpected faults may occur; for example, other IEEE1394 devices may not function normally. It is therefore strongly recommended that, after downgrading the IEEE1394 device driver, you avoid using any other IEEE1394 devices with that PC.
