The 4060 card should have come with installation instructions, but appears that it did not, or you would not be asking. Try to google an answer online, or you might be able to find the correct settings for the card at the "Big Book of Amiga Hardware" website. The settings on your A4000 motherboard should not change from using an A3640 to using the GVP 4060 as they are both external accelerators that use the accelerator slot and not a CPU on the motherboard.
