assigned to only one device. In an standard design there are 16 IRQs available but most of
them are occupied by the system and leaves 6 free for expansion cards.
With most recent device, the BIOS automatically assign an IRQ number to PCI expansion
cards. Please make sure there are no any of two devices use same IRQs, otherwise your
computer may experience some problems when those two devices are in use at the same time.

described above. You can select a DMA channel in the PCI and PnP configuration section of
the BIOS Setup utility.

1. Power Connector: AT Power Connector (12-pin block): ATPOW
This connector connects to a standard AT power supply. To connect the leads from the
power supply, ensure first that the power supply is not plugged. Most power supplies
provide two plugs (P8 and P9), each containing six wires, two of which are black. Orient

Using a slight angle, align the plastic guide pins on the lead to their receptacles on the
connector. Once aligned, press the lead onto the connector until the lead locks into place.
