    GEMSTAR UP-GRADE How to upgrade the Gemstar by G-Link * Note Upgrading the Gemstar by G-Link should have the boot ROM at the flash ROM of the Gemstar board. So, if there is no data at the flash ROM, this method is not possible, but possible for upgrading only. 1) Connect the G-Link cable to the G-Link connector of the Gemstar board.
  • Page 40 4) After the DOS window of the step 3 is popped up, the following window will be popped up. 5) After the window of the step 4, apply the power to the Gemstar board. Because the live power is applied at the SET state, if the Gemstar board is built in, disconnect the plug and plug it after 3 seconds, but if not, plug the Gemstar board to the set and connect the power plug.
  • Page 41 7) The following message is displayed and upgrading continues. 8) When upgrading is completed, the following is displayed and all steps are finished. Upgrading takes about 6 minutes even it varies depending on the upgraded flash. 3-29...
