The Setup program allows users to modify the basic system configuration and save these settings to CMOS RAM. T he power of CMOS RAM is supplied by a battery so that it retains the Setup information when the power is turned off. Basic Input-Output System (BIOS) determines what a computer can do without accessing programs from a disk.

Clear NV RAM T his item allows you to clear the data in the NVRAM (CMOS) by selecting "Yes". Options: No (Default) / Yes Plug & P lay OS When set to YES, BIOS will only initialize the PnP cards used for the boot sequen ce (VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP operating system like WindowTM 95. For non-PnP operating systems (DOS, NetwareTM), this option must set to NO. Options: No (Default) / Yes 16 A770L3 BIOS Manual PCI Latency Timer T his item controls how long a PCI device can hold the PCI bus bef another takes ore over. T he longer the latency, the longer the PCI device can retain control of the bus before handing it over to another PCI device. Options: 64 (Default) / 0-255 Allocate IRQ to PCI V GA T his item allows BIOS to choose a IRQ to assign for the PCI VGA card.
