[. . . ] But if you have trouble connecting to your parallel port device, switch to EPP1. 7. · EPP1. 7 · EPP1. 9 ECP Mode Use DMA This BIOS feature determines which DMA channel the parallel port should use when it is in ECP mode. Please note that there is no performance advantage in choosing DMA Channel 3 over DMA Channel 1 or vice versa. As long as either Channel 3 or Channel 1 is available for your parallel port to use, the parallel port will be able to function properly in ECP mode. ·3 ·1 54 3. 6. 3 Onboard Device Onchip USB Controller This option enables or disables IRQ allocation for the USB (Universal Serial Bus) controller. If you disable this while using a USB device, you may have problems running that device. However, if you don't use any USB devices, set the option to Disabled. · Enabled · Disabled Note: This option is for the older USB 1. 1 specification USB 2. 0 Controller This option enables or disables IRQ allocation for the USB 2 (Universal Serial Bus -Specification 2. 0) controller. If you disable this while using a USB 2 device, you may have problems running that device. However, if you don't use any USB 2 devices, set the option to Disabled. · Enabled · Disabled Note: USB 2. 0 has a throughput of 480 Mbps (40 times faster than USB 1. 1) and is fully backward compatible with USB 1. 1. 55 USB Keyboard Support via You may choose when to have USB keyboard support, via OS or BIOS. · OS · BIOS USB Mouse Support via You may choose when to have USB mouse support, via OS or BIOS · OS · BIOS IEEE 1394 Controller This enables/disables the onboard 1394 (FireWire) controller. · Enabled · Disabled Onboard PCI LAN Controller This controls if the onboard Lan will is run on boot up. Lan Boot ROMs are used to download operating system code from a network server. Options are: · Enabled · Disabled Invoke Boot Agent · Enabled · Disabled 56 3. 6. 4 PCI Express Root Port Function This option enables the BIOS to detect the PCI devices attached to the four PCI Express ports. PCI Express LAN1/LAN2 Controller When enabled, the BIOS checks these ports to detect and activate the PCI devices connected to them. · Enabled · Disabled Invoke Boot Agent · Enabled · Disabled PCI-E Compliancy Mode This BIOS option determines compatibility between PCI-Express specification v1. 0 and PCIExpress specification v1. 0a. · V1. 0a · V1. 0 57 3. 7 Power Management Setup Options related to power management can be altered through the following: ACPI Suspend Type ACPI (Advanced Configuration and Power Interface) establishes industrystandard interfaces for OS-directed configuration and power management on laptops, desktops, and servers. ACPI allows the Operating System (instead of the BIOS) to control Power Management (OSPM). The ACPI Standard defines hardware registers (which are implemented in chipset silicon), BIOS interfaces, which include configuration tables, control methods, and motherboard device enumeration and configuration; system and device power states, and the APCI thermal model. All devices in the system can communicate with each other about resource use. The operating system has the most knowledge on a running system's state, and so is in the best position to perform power management. · S1 (POS) (Power On Suspend): In this method, the processor does not execute instructions but remains connected to the bus; the processor preserves the state and content of its internal registers, along with the dynamic context of the memory. [. . . ] Striping: see RAID UltraDMA-33/66/100: a fast version of the old DMA channel. Without proper UltraDMA controller, your system cannot take advantage of higher data transfer rates of the new UltraDMA/UltraATA hard drives. This one port type can function as a serial, parallel, mouse, keyboard or joystick port. It is fast enough to support video transfer, and is capable of supporting up to 127 daisy-chained peripheral devices. [. . . ]
