ELSA Graphics Board Addresses
The ELSA graphics boards are 100% IBM VGA compatible and occupy memory and sev-
eral I/O addresses accordingly. To ensure the proper functioning of your system, it is
essential to make sure that the I/O and memory addresses occupied by the graphics
board are not used by other hardware components
This affects the following addresses:
I
Higher memory ranges (above 1 MB) will be allocated via the PCI BIOS interface. If you
come across any address conflicts, try to modify the I/O address of the expansion board
causing the conflict. The addresses of the ELSA graphics boards cannot be changed.
The VGA D Socket
Pin Assignment
The WINNER 2000/Office issues analog signals in accordance with the requirements of
Guideline RS-170. The synchronization information is sent separately. If your monitor
provides a switch for the input impedance, you should select '75 Ohms' (= '75
Ω
') for the
R, G and B video inputs and '2 kOhm' (= '2 k
Ω
') for the sync inputs. You should only try
other switch settings at the sync inputs if your monitor expects sync levels other than
those used by normal monitors and does not produce a stable display. The switches are
labeled “Low” and “High” only on some monitors. You can then refer to your monitor
