Publisher review:
Do not forget to set a system restore point before installing Sony DRX-500UL/500ULX DVD-RW Firmware 2.1a driver, to avoid problems that may occurs when you install a
wrong driver, or for other OS version etc. If a problem occur than you may restore you computer to previous time, before installing the driver.
Operating system:
Windows 98SE/ ME/ 2000/ XP
