What motherboard does your 16804A have? The BIOS boot screen should display that information. It should be either an Intel D915GUX, or an ADLINK M-880. (There were also newer versions with an ADLINK M-890 motherboard, but those should be running Windows Embedded Standard 7, and they are also obvious by having a DVI video port on the back panel instead of a VGA port).
For the Intel D915GUX motherboard 16804A you want the 16800-14102 recovery DVD.
For the ADLINK M-880 motherboard 16804A you want the 16800-14103 recovery DVD.
If you boot from those recovery DVDs it will install an activated Windows XP system image. Then the logic analyzer application needs to be installed separately.
As the 16800 series do not have a built-in DVD drive, you will need to boot from an external USB attached DVD drive.
The 16800-14102 and 16800-14103 recovery DVD .ISO images are available, although currently a bit of a pain to download.
