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. [. . . ] T his is a useful feature when using such USB devices with operating systems that do not natively support USB (e. g.

USB Mass Storage Reset Delay T his item allows you to set the reset delay for USB mass storage device. Options: 20 Sec (Def ault) / 10 Sec / 30 Sec / 40 Sec Emulation Type T his item allows you to select the emulation type of the USB mass storage device. Options: Auto (Default) / Floppy / Forced FDD / Hard Disk / CDROM 16 A770 A2G+ BIOS M anual 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.

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 17 A770 A2G+ BIOS M anual 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) / 32 / 96 / 128 / 160 / 192 / 224 / 248 Allocate IRQ to PCI V GA T his item allows BIOS to choose an 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 information 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.
