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. [. . . ] AUTO option disables legacy support if no USB devices are connected. > USB Mass Storage Device Configuration USB 1. 1 Controller [Enabled] USB 2. 0 Controller [Enabled] vxx. xx (C)Copyright 1985-200x, American Megatrends, Inc. Legacy USB Support T his item determines if the BIOS should provide legacy support fo r USB devices like the keyboard, mouse, and USB drive. T his is a useful feature when using such USB devices with operating systems that do not natively support USB (e. g. Options: Enabled (Default) / Disabled USB 2. 0 Controller Mode T his item allows you to select the operation mode of the USB 2. 0 controller. Options: HiSpeed (Default) USB 2. 0-480Mbps FullSpeed USB 1. 1-12Mbps BIOS EHCI Hand-Off T his item allows you to enable support for operating systems without an EHCI hand-o ff feature.

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 18 N68S3B 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. Options: Enabled (Default) / Disabled OffBoard PCI/ISA IDE Card Some PCI IDE cards may require this to be set to the PCI slot number that is holding the card. Options: Auto (Default) / PCI Slot1 ~ 6 OffBoard PCI/ISA Primary & Secondary IRQ T his item allows you to set IRQ of non-onboard PCI/ISA IDE controller adapter.
