Setup

1. Download and install CGOS for the appropriate operating system
2. Download and install CGUTIL for the appropriate operating system
3. Under windows, CGUTILGUI should be copied into the same directory as cgos.dll,
   i.e. \Cgos\WIN\BIN
4. Running CgosDump with Admin rights automatically installs the driver.

 

To add a display/resolution dataset to the BIOS

5. Press the ‘Update Selected Data Set’

   • Note the default extension for the tool is .bin but this can be confused with other congatec BIOS modules.  Preferrable to use a .epi extension
   • For Connect Tech sales demos , select oem800x480_18bit.epi.  in \\nasmain\scr\qseven\common\drivers&fw\congatec\congaQA\Bios\cti_custom\QMENR113
7. Click close.
