An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a mercury-vapor lamp). EPROMs are easily recognizable by the transparent fused quartz window in the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.
A basic input / output system customization method and apparatus
The application relates to a basic input / output system customization method and device, and the method comprises the following steps: based on an open source computer operating system kernel and a basic input / output system shell environment, generating a flash read / write tool associated with a flash EPROM; based on the flash read / write tool, writing basic input / output system customization information into the flash EPROM; obtaining the basic input / output system customization information of the flash EPROM, and realizing basic input / output system customization based on the basic input / output system customization information. The method can realize the requirement of basic input / output system customization, improve the compatibility of basic input / output system code, effectively improve production efficiency, simplify operation process, and optimize the production mode of customized products.
