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. [. . . ] Options: Auto (Default) / Floppy / Forced FDD / Hard Disk / CDROM 15 A780L M2G+/A780L M2L+/A780L BIOS Manual 3 PCIPnP Menu T his section describes con figuring the PCI bus system. PCI, or Personal Computer Interconn ect, is a system which allows I/O devices to operate at speeds nearing the speed o f 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.

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 A780L M2G+/A780L M2L+/A780L 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. Options: Yes (Default) / No Palette Snooping Some old graphic controllers need to " snoop" on the VGA palette and then map it to their display as a way to provide boot inf ormation and VGA compatibility. Options: Disabled (Default) / Enabled PCI IDE BusMaster T his item is a toggle for the built-in driver that allows the onbo ard ID E controller to perform DMA (Direct Memory Access) trans fers.
