Technical data

Those with a technical interest will find more detailed information regarding the

ELSA

ERAZOR X and ERAZOR X²

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 ERAZOR X 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.
