Installing the KenWood 72x TrueX CD-Rom was an easy process. KenWood suggests putting the drive as Master in any IDE channel, so we installed it as Master into the Second IDE channel. After booting, the CD-Rom identified itself as KenWood UCR-421 into both the BIOS & Windows 98 SE. Afterwards, we unchecked the auto-insert notification.

KenWood 72x TrueX CD-Rom was a January 2000 model with v2.08 firmware revision. Our lookout at the KenWood's US website revealed a new firmware revision (v2.17), which we immediately downloaded and updated the drive with it. This version added support for UDMA and improved readability with CDRW discs. If you plan to update your KenWood drive under NT, avoid it, since many users reported problems after trying it. Instead go on if you run Win9x. After we updated the firmware and enabled the UDMA setting in Win98SE, all was set for the benchmark party to begin! We also had the change to get a second KenWood 72x TrueX CD-Rom unit for double checking benchmark results... ;)
