Dolphin ROM Image and Boot Loader

Upgrading the Dolphin ROM Image

Important Notice: Before installing the Dolphin OS and Development System, you must remove all
previous installations. To do this, delete the C:\DOLPHIN directory and all files contained within
as well as the Dolphin Group or Folder. Only install the most recent release of the Dolphin ROM
IMAGE and Boot Loader. Loading an old version of the ROM IMAGE or Boot Loader can
make the Dolphin unstable or inoperable, and requiring you to return the unit to HHP for repair.
The Dolphin terminal has a Boot Loader incorporated that allows the developer to
upgrade or reload the ROM IMAGE.
Follow these steps to manually reload the ROM IMAGE and Operating System from
DOS:
1.
Verify that Configuration Switch 2 on the back of the Dolphin HomeBase is set to
"Fixed BPS" and Switch 1 is set to "Single". Power must be turned off and then
on to accept the new dip switch settings.
2.
Make sure the serial cable is properly installed and power is properly connected to
the HomeBase. Make sure no other communications programs are running on the
PC.
3.
Start the Dolphin Boot Loader. Hold down the "7" and "9" keys with one hand.
With your other hand, press and release the "ON/SCAN", "SHIFT" and "BKSP"
keys. Release the "7" and "9" keys. You should see the screen below. If not,
repeat step three.
4.
Press "3" to select Baud rate. Press "1" to set baud rate to 57600.
