BIOS stands for basic input/output system, and it is a firmware. It was first used by IBM PCs; however, companies later reverse-engineered it in order to create compatible versions for other systems.

PlayStation 1 emulation requires the use of a plugin system. Hence, the ePSXE emulator is merely the shell of the operation. One of the plugins required for the emulation to succeed is the BIOS file. Once the BIOS file is loaded, the user is then able to configure the settings and load the games. The BIOS is what allows the player to use his device's capabilities, emulating the console hardware. BIOS files for game console emulators are available throughout the Web in different versions that offer variable compatibility.
