Technical data
Those of you with a technical bent will find more detailed information regarding the
ELSA
SYNERGY II in this chapter. All interfaces and their assignments are described in detail.
Characteristics of the graphics board
ELSA graphics board addresses
The ELSA graphics boards are 100% IBM VGA compatible and occupy the same memory
area and specific addresses in the I/O range. The memory range above 1MB is automat-
ically assigned through 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 SYNERGY II also requires an interrupt (IRQ) which is free. This may have
to be reserved in the computer’s BIOS. For help with this theme, refer to the manual for
your mainboard.
To ensure that your system functions properly, the addresses and ranges occupied by the
ELSA graphics board must not be accessed simultaneously by other hardware compo-
nents. The following addresses are assigned:
K
I/O addresses:
Standard VGA I/O (3B0-3DF)
K
Memory addresses:
Video RAM (A0000-BFFFF)
Video BIOS-ROM (C0000-C7FFF)
