This is the case for upgrading if the below points apply:
•
The H
is equipped with a prior model of the single board computer (233 MHz processor speed) and with
YDRA
version 9 or higher of the overlay input card.
•
And the H
was operated with an output resolution for projection modules with 1024×768 (XGA) pixels

The H
is equipped with a prior model of the single board computer (233 MHz processor speed) and with

version 8 or lower of the overlay input card.
In both cases attention must be paid to the BIOS settings. In the first case (upgrading) the BIOS settings have to
be changed to SXGA (1280×1024 pixels). The BIOS set
