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 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 graphics board 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 components. the following addresses are assigned:

    1 i/o addresses:

    standard vga i/o (3b0-3df)

    2 memory addresses:

    video ram (a0000-bffff)

    video bios-rom (c0000-c7fff)
