2. ¿ What is the BIOS and what is? The BIOS is a firmware installed on computers, contains the basic instructions for them to function and perform adequately, basic routines may include control devices ¿ WHAT IS A FIRMWARE? is a block of instructions for very specific purposes, are of type ROM, set logic low level, and this is why, in order to control the electronics of a device of any kind.Now the firmware is considered a hybrid between software and hardware, to be integrated into the electronic part, belongs to the hardware, but in turn also provides Software as logic and set to a programming language, in this case Assembler code
3. THREE TYPES OF BIOS AND DIFFERENCE IN THE METHOD THAT IS USED TO RECORD ROM ---> It can only record at the time the chip is manufactured. N The information it contains will not be altered. EPROM --->Erasable Programmable Read-Only Memory (ROM programmable borrable). Estos chips se pueden grabar con luz ultravioleta. En la parte superior del chip se puede apreciar una especie de ventanilla transparente, que suele estar tapada con una pegatina. Estas BIOS se encuentra principalmente en 286 y 386. EEPROM( ElectricalErasable and Programable Read-OnlyMemory), that means, read-only memory that can be erased and more, can be programmed electrically
4. BIOS access and manipulation To access the BIOS Setup program, usually called CMOS Setup, we will do this by pressing a button during the initial start up your computer. Usually it the Delete key but this varies by type of plate Delete key,Del key,"F2""Ctrl + Alt + Esc""F1"Key "F10""Ctrl + Alt + S"
