General description
Charon-AXP supports emulation of PBXGA graphics card(s) by direct virtualization and provides a virtual console for displaying graphics.
The console starts automatically upon starting the emulator. Its resolution is 800 x 600 by default.
Emulated cards
- PBXGA_AA - ZLXp-E1 (8bpp, PseudoColor)
- PBXGA_BA - ZLXp-E2 (24bpp, TrueColor)
...
- PBXGA graphics console cannot be used as the system console. Use OPA0 for this purpose.
- If PBXGA graphics card is going to be used, the resolution of CHARON host screen must be sufficient to provide ability to display the graphics console properly.
- If PBXGA graphics card is used, CHARON cannot run as a service so not compatible with the Linux Toolkit. It can however work in detached mode.
- If the window of the PBXGA graphics card console is closed by user or killed as a process, it will not re-appear automatically (
the Charon emulator will continue to work). In this situation the user has to restart the pbxga_tv program with the correct parameters, as defined in the configuration file, to restart the graphical display (see application chapter further)
