PCI, or Personal Computer Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed of the CPU itself uses when communicating with its own special components. Notice Beware of that setting inappropriate values in items of this menu may cause system to malfunction.

The rest of the cards will be initialized by the PnP operating system like WindowTM 95. When set to NO, BIOS will initialize all the PnP cards. For non-PnP operating systems (DOS, NetwareTM ), this option must set to NO. Options: No (Default) / Yes 16 A740G M2+ BIOS Manual PCI Latency Timer This item controls how long a PCI device can hold the PCI bus before another takes over. The longer the latency, the longer the PCI device can retain control of the bus before handing it over to another PCI device.
