Yes, ROM BIOS chips on modern motherboards can typically be reprogrammed, but the process usually involves using a firmware update rather than directly rewriting the chip. Most motherboards use flash memory, which allows for easy updates to the BIOS firmware without needing to replace the chip itself. Users can update the BIOS through the motherboard's built-in utilities or by using software provided by the manufacturer. However, caution is advised, as improper flashing can lead to system instability or failure.
Nearly all computers manufactured today have motherboards which use bios chips based on flash memory technology
BIOS stands for Basic Input/output System. It is software that is built into computers. A BIOS that can be reprogrammed using software is called EPROM.
Flash BIOS ROM is a type of non-volatile memory used in motherboards to store the firmware that initializes hardware components during the boot process. Unlike traditional ROM, flash memory can be easily updated or reprogrammed, allowing users to upgrade the BIOS for improved compatibility, performance, or added features. This capability is crucial for maintaining system stability and supporting new hardware technologies. The process of updating the BIOS is commonly referred to as "flashing the BIOS."
threw your motherboards bios which can be accessed at startup
Two examples are resetting the BIOS to the default settings and swapping between two different BIOS chips for boards with multiple BIOS.
No a worm can not in theory damage a motherboard, however they can damage your bios rendering motherboard unusable would have to either target a small subset of motherboards or build a large library to make the worm worthwhile,as a precaution change the jumpers to write protect your Motherboards bios
You can flash the BIOS. I wouldn't recommend it, as it won't give much of an improvement UNLESS you're experiencing BSOD, crashing, etc. If this is the case you can go to your motherboard manufacturers website and they should have a BIOS update you can d/l.
They are called eproms or eeproms
Read Only Memory(ROM) Basic Input Output System(BIOS) or firmware chips are "Electrically Erasable and Programmable Read Only Memory(EEPROM)" chips, these kind of chips can be upgraded by flashing.
ACPI Function
BIOS is not dependent on the form factor (ATX) of the motherboard. BIOS are chips with information on how to run certain hardware, these are usually American Megatrends, Award, or Phoenix.
Two common types of BIOS ROM are the EPROM (Erasable Programmable Read-Only Memory) and Flash memory. EPROM can be erased using UV light and reprogrammed, while Flash memory can be electrically erased and rewritten, allowing for easier updates. Modern systems typically use Flash memory due to its flexibility and convenience.
