HP Pluggable SCSI PX-40TSi CDROM firmware upgrade 1.1x to 1.12 Caution This is not the official firmware 1.12 release from HP or Plextor Use it at your own risk. Author aharjono@yahoo.com History I saw Plextor has released its firmware 1.12 for its Ultraplex PX-40TSi. Since I owned a Plextor made HP PX-40TSi, which is indeed exactly the same as Plextor Ultraplex PX-40TSi, I am also interested in flashing my PX-40TSi from firmware 1.11 to firmware 1.12. I downloaded the 1.12 firmware from Plextor web site and tried to flash mine. However, it did not work on HP PX-40TSi. Then, I searched all HP website, hoping that I could find the firmware. But it was not there. I contacted Plextor tech support, hoping that they could "spare" me with the latest 1.12, but they refuse to help me, since it's not their duty to support an OEM products although Plextor made it. In my confusion, I decided to take a peek at Plextor flashing program. First I extract the files using Winzip, inside I saw two files, one is the flashing program and the other is the firmware image. I decided to disamble the flashing program first, since I was sure that this was where the CDROM checking start. I used Advanced Xex Editor version 2.1 and start to hack the program. And I did it. How to flash Under Windows (I am using Windows Me), extract the two files and double click plfirm32.exe, wait until it's completed and restart your computer. Thanks to : Plextor for releasing this firmware (www.plextor.com) Winzip for allowing me to extract the files (www.winzip.com) A.X.E (Advanced heX Editor) for allowing me to hack the program (www.kahei.com)Download Driver Pack
