File Extension ROM
File extension ROM is used to describe files that contain data referred to as firmware which is used by computer hardware. These files are used to update data stored on computer systems were ordinary files and executables are restricted. Such uses include the update file for the BIOS and other hardware components on a system that contain read-only-memory modules like Video Cards. ROM files are readable by different applications designed for a certain hardware installed on computers running with Windows, Mac, and Linux.
Instructions written on ROM files serve as mediators between the hardware and the operating system. A certain ROM file is associated to a hardware connected and used by a computer system in order to provide the operating system with information about the mounted device. For use as an update for the BIOS firmware, a ROM file can be downloaded from the BIOS manufacturer's website and updated through a flash program.
Apart from its use as an update file for computer hardware, ROM files are also used by other applications and devices to function. This includes the use of such extension for the popular game console Nintendo 64 (N64). Game files from this console are stored in a read-only file that can be opened by the device.
No threats have been recorded in connection with the use of ROM files to launch devastating computer attacks. However, there are theories formulated by security experts that these files can be hijacked and recoded in order to provide wrong information to a system's ROM.
A scenario involving the use of this extension to spread fears of computer attacks was recorded way back in 2000 when Kaspersky Lab, a renowned anti-virus software developer, discovered a memory resident virus that uses ROM as part of its filename. The Virus.DOS.Rom.331 is classified by the company as a non-harmful virus whose payload includes the modification of executed COM files. Once infected, the virus warns a computer user about an incompatibility with the system's ROM BIOS.
There are few applications that can be used to open ROM files. This includes memory flashers supplied by various computer motherboard manufacturers to allow users to update their computer's BIOS information. Asus EZ Flash and the AFUDOS utilities are two utility applications offered by Asus for updating their motherboard's BIOS.
