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:

KMemory addresses: Video RAM (A000-BFFF) Video BIOS-ROM (C000-C7FF)
