Next, I am going to look at doing firmware updates on some lenses. When a computer is turned on, the BIOS launches instructions that check the machine’s startup process for potential errors. It starts by checking the random access memory and processor for faults, then checks connected devices, such as a keyboard and mouse, for any problems. It then checks for a boot sequence, such as Boot from Compact Disc Read-Only Memory (CD-ROM) and Boot from Hard Drive. Finally, the BIOS connects to the bootloader program, which wakes up the computer’s operating system and loads it in the RAM. Device drivers are programs that enable interaction with hardware devices.

In August 2015, Google announced that devices in the Google Nexus series would begin to receive monthly security patches.

Subsystem firmware often comes as part of an embedded system. It is comparable to high-level firmware in that it can be updated and is more complex than low-level firmware. One example is a server’s power subsystem, which is a piece of server hardware that functions semi-independently from the server. As the manufacturer of your gear creates newer and better firmware, updates add or rewrite the existing software on the device so it works at maximum efficiency and security again.
