(Primary or Secondary) -Find out whether the target DVD-ROM drive is set as a Master or Slave. If you are uncertain as to how to find what IDE bus your DVD-ROM drive is connected to, consult your system builder. 1. Download the appropriate zip file for the target DVD-ROM drive. Recommended save locations are C:\ or A:\.(Because Directory names more than 8 characters are truncated in MS-DOS, it is recommended the name of the directory to which the zip file is saved be no longer than 8 characters) 2.

UPG4.EXE Firmware file.......... ASPIOxxx.HEX (xxx's refer to the firmware revision) 3.
