BIOS setup

(redirected from CMOS settings)

BIOS setup

A program used to edit hardware settings in the BIOS of a PC. On earlier PCs, users had to change a setting when a new drive was added, but auto-detect features were later added. Although some settings are quite arcane and modified only by experienced technicians, users sometimes may need to make a change, such as the boot order of the PC (see first boot sequence).

From CMOS to Flash
The BIOS setup has also been called the "CMOS setup" or "CMOS RAM," because settings were initially held in a battery-backed CMOS memory circuit. Subsequently, BIOS settings were stored in non-volatile flash memory.

Accessed at Startup
The BIOS setup is accessed at startup. Soon after a PC is turned on, a short screen message typically passes by very quickly indicating which key to press (usually Esc, F1, F12 or Del). See BIOS, hard disk configuration, BIOS Upgrades and CMOS.

The all new Kabini APU s CMOS functions have been integrated into the APU; this means that when the user removes the APU, all CMOS settings revert to factory defaults.
Embedded enhancements added by Ampro include watchdog timer, battery-free boot (in case the battery for CMOS settings fails or is not installed for harsh environments), serial console, and BIOS recovery.
Even if the on-board battery fails, the board will continue to boot normally, using the correct CMOS settings stored safely by the Ampro embedded BIOS.
It's best to replace this (or have someone replace it for you) before it actually dies so you can make a note of your CMOS settings.
Users can access all levels of PC control, from CMOS settings to power cycling servers, connected with either a Cybex KVM switch or other keyboard- controlled KVM switch.
All E-series servers offer a comprehensive set of server management tools for remotely managing BIOS updates and CMOS settings.
The captured image contains all system software, networking software, associated drivers, software applications, configurations, and all the files, including deleted files, slack space, and data files as well as the CMOS settings for the system.
