Managing and updating your bios Best telugu chat rooms
Also, many ongoing functions, such as getting a keystroke from the keyboard, reading and writing disk sectors, and power management are handled by the BIOS.
The BIOS accomplishes its tasks via a standard library of functions, often referred to as BIOS “calls” or “functions” which the operating system and application software uses to carry out tasks or get information on system resources.
If they do not, there is usually video driver information on another ROM on the motherboard that the BIOS can load.
Next, the BIOS checks to see if this is a cold boot or a reboot.
With contemporary EEPROM (Electronically Erasable Programmable Read Only Memory) technology – the successor to the original ROM BIOS – it’s possible to change the contents of the ROM BIOS electrically via software.
Interrupt handlers are small pieces of software that act as translators between the hardware components and the operating system.
The first thing the BIOS does is check the information stored in a tiny (64 bytes) amount of RAM located on a complementary metal oxide semiconductor (CMOS) chip.
The CMOS Setup provides detailed information particular to your system and can be altered as your system changes.
It checks the PS/2 ports or USB ports for a keyboard and a mouse.
It looks for a peripheral component interconnect (PCI) bus and, if it finds one, checks all the PCI cards.
