[. . . ] Select "Enabled" to activate the first and / or second IDE interface. If you install a primary and / or secondary add-in IDE interface, select "Disabled" to deactivate an interface. If you highlight the literal "Press Enter" next to the "Onchip IDE Control" label and then press the enter key, it will take you a submenu with the following options: 18 P4M800-M7A BIOS Manual OnChip SATA This option allows you to enable the onchip Serial ATA. IDE Channel 0/1 The motherboard chipset contains a PCI IDE interface with support for two IDE channels. Select "Enabled" to activate the first and/or second IDE interface. Select "Disabled" to deactivate an interface if you are going to install a primary and/or secondary add-in IDE interface. IDE Prefetch Mode The "onboard" IDE drive interfaces supports IDE prefetching for faster drive access. If you install a primary and/or secondary add-in IDE interface, set this option to "Disabled". IDE Primary / Secondary Master / Slave PIO The IDE PIO (Programmed Input / Output) fields let you set a PIO mode (0-4) for each of the IDE devices that the onboard IDE interface supports. In Auto mode, the system automatically determines the best mode for each device. IDE Primary / Secondary Master / Slave UDMA Ultra DMA/100 functionality can be implemented if it is supported by the IDE hard drives in your system. As well, your operating environment requires a DMA driver (Windows 95 OSR2 or a third party IDE bus master driver). If your hard drive and your system software both support Ultra DMA/100, select Auto to enable BIOS support. IDE HDD Block Mode If your IDE hard drive supports block mode, select "Enabled" for automatic detection of the optimal number of block read/ writes per sector the drive can support. The Choices: Enabled (default), Disabled. 19 P4M800-M7A BIOS Manual VIA OnChip PCI Device If you highlight the literal "Press Enter" next to the "OnChip PCI Device" label and then press the enter key, it will take you a submenu with the following options: VIA-3058 AC97 Audio This option allows you to control the onboard AC97 audio. The Choices: Auto (default), Disabled. VIA-3068 AC97 Audio This option allows you to control the onboard AC97 audio. The Choices: Auto (default), Disabled. VIA-3043 Onchip LAN The Choices: Enabled (Default), Disabled. Onboard LAN Boot ROM This item allows you to enable or disable the Onboard LAN Boot ROM controller. The Choices: Enabled, Disabled(default). Onchip USB Controller Select "Enabled" if your system contains a Universal Serial Bus (USB) controller and you have USB peripherals. The Choices: All Enabled (default), All Disabled. On-chip EHCI Controller This item allows you to enable or disable the on-chip EHCI controller. USB Device Function The Choices: Enabled, Disabled(default). 20 P4M800-M7A BIOS Manual USB Emulation Do not support any USB device on Dos The Choices: On (default), Off. USB Keyboard/ Mouse Support This item allows you to enable or disable the USB Keyboard/ Mouse Legacy Support. The Choices:Disabled (default), Enabled. Super IO Device If you highlight the literal "Press Enter" next to the "Super IO Device" label and then press the enter key, it will take you a submenu with the following options: Onboard FDC Controller Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you wish to use it.

Some graphic controllers which are not VGA compatible take the output from a VGA controller and map it to their display as a way to provide boot information and VGA compatibility. However, the color information coming from the VGA controller is drawn from the palette table inside the VGA controller to generate the proper colors, and the graphic controller needs to know what is in the palette of the VGA controller. To do this, the non-VGA graphic controller watches for the Write access to the VGA palette and registers the snoop data. [. . . ]
