Embodiment Construction

[0038] The core of the present invention is to use the bootrom software as the network device of the boot program, increase the command of enabling or prohibiting the bootrom access control in its application program, and write the corresponding Result identification, when the network device is powered on and restarted, corresponding processing is performed according to the result identification before the bootrom password login judgment: if the bootrom access is prohibited, the password login process is no longer performed, but the device application program is directly guided to start; as Check to allow bootrom access, enter the password verification interface, and perform corresponding operations according to the password entered by the user.

[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodimen...

Abstract

This invention discloses a safely access method for system bootrom including: designing a system bootrom access control order, when the system operates in the applied program, it controls the bottom access state by accessing the control order. When the system operates bootorm, it controls users to access the bootrom band on the access state of the bootrom, which can increase the safety for accessing the bootrom.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a system bootrom security access method. Background technique [0002] The bootrom (boot chip) software is a device that uses a real-time operating system to start a boot program, such as an Ethernet switch, a router, and other devices. Inside the CPU (central processing unit) chip, a small boot (start) program is embedded, similar to The storage area of ​​the BIOS (Basic Input / Output System) on the motherboard of a PC. When the device starts, the bootrom software moves the application program of the device to the designated location in the memory and starts running. In addition, the bootrom software also has functions such as device power-on self-test, file download and upgrade, and flash (flash memory) management. Usually, the bootrom chip is flash (flash memory) or E2PROM (electrically erasable memory). In order to facilitate the maintenance and management of...
