Some early IBM computers require you to press and hold both mouse buttons as the computer boots to enter the BIOS setup. See the computer manufacturers list for contact information. Because these diskettes are unique to your computer manufacturer, you must obtain the diskettes from them. These diskettes may be referred to as ICU, BBU, or SCU disks. BIOS or CMOS diskettesĮarly 486, 386, and 286 computers required a floppy disk to enter the BIOS setup. Older AMI BIOS could be restored to bootable settings by pressing and holding Insert as the computer is booting. While holding F10, two beeps should be heard to indicate the settings are restored. If your Acer computer cannot boot or you want to restore the BIOS to its original settings, press and hold the F10 as you turn on the computer. Below is a listing of key sequences to press as the computer boots to enter the BIOS setup. Unlike today's computers, older computers (before 1995) had numerous methods of entering the BIOS setup. If F10 doesn't work, look at the bottom or top of the screen for the key that's used to save the settings. If any changes are made, you need to save those changes, which is usually done by pressing the F10 key on the keyboard. For help with replacing the battery, see: How to replace the CMOS battery. The on-board LAN controller is a highly integrated 100 Mbit LAN / GbLAN controller.If changes you made appear to revert to default settings, or the date and time setting in the BIOS keeps falling behind, you may need to replace the CMOS battery. USB2.0 provides up to 480Mbps data transfer rate, supports hot swap, Compatible with USB 2.0 standard,Easy connection to various USB interface devices. This motherboard supports hard drives based on the Serial ATA (SATA) 3Gb/s storage specifications, delivering enhanced scalability and doubling the bus bandwidth for high-speed data saving and retrieval. With a bus bandwidth 4 times higher than that of AGP 8X interface, PCI Express x16 bus performs much better than AGP 8X in applications such as 3D gaming. PCI Express is the latest I/O interconnect technology that will replace the existing PCI. This motherboard supports DDR2 memory that features data transfer rates of 800/533 MHz It especially includes Intel® Fast memory bandwidth and reduces the latency of the memory accesses The Intel® G31 Express Chipset is designed to support dual-channel DDR2 800/533, 800/533/667 MHz Front Side Bus (FSB), PCIe 1.1, and mutli-core CPUs. This motherboard supports Intel® LGA775 Core™ 2 Extreme/Core™ 2 Quad/Core™ 2 Duo/Pentium™ D/Celeron™ D processors, which are excellent for multitasking, multimedia, and enthusiastic gamers with 800/533/667 MHz FSB.
