All the instructions and procedures needed to start up a computer, to the point it can load an operating system, are stored in ROM chips. In IBM compatible PCs this is called the ROM BIOS.
ROM Basic Input Output System The BIOS in a PC stored on a ROM chip. Early PCs used a ROM BIOS, but PCs today use a flash memory BIOS because it can be updated in place. In order to update a ROM BIOS, the computer case had to be opened, and the ROM chip had to be located and replaced.
The BIOS stands for Basic Input/Output System and is stored permanently on ROM (read Only Memory) Any changes are held in RAM (I think) and remain while the PC battery has power (the little button battery on the motherboard) The BIOS lets the PC boot up into the basic level and allows the PC to read the hard drive.
Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. In modern computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.
