Characteristics of the Graphics Boards
Address Assignment of the
ERAZOR II and
VICTORY Erazor LT
The ELSA ERAZOR II and ELSA VICTORY Erazor LT graphics board are fully IBM VGA com-
patible and occupies the same memory area and specific addresses in the I/O range. The
memory range above 1 MB is automatically 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 ELSA ERAZOR II and ELSA VICTORY Erazor LT 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:
