No, not all systems use the same method to enter CMOS setup. Some systems allow access to CMOS setup by pressing DEL during start up and others by pressing F2.

Generally, no, you cannot enter the CMOS setup after you have booted. But it depends on the exact computer and if there is a separate CMOS configuration tool. In fact, the IBM AT was like that, and it required a separate setup program that ran after the computer booted. Some of the modern computers will let you change certain CMOS settings on the fly if you install a utility their utility for doing that.
Cmos ram.
Most CMOS allow the administrator to add or edit a supervisor password. Enter your CMOS using whichever key your motherboard needs to open the CMOS (this will be displayed on the first screen of bootup), then find the general settings tab or a name similar and press enter on the password field. After that, enter your password and when you boot to your CMOS it will ask for your password.
Configure security through the CMOS setup utility.
To access and modify the CMOS data, you would need a CMOS setup utility. Originally, in the IBM AT and a few close clones, it required a separate utility on a diskette. However, manufacturers soon added this utility the the ROM BIOS. So even today, all you have to do is enter CMOS setup is to press a certain day upon booting the system. Delete, F1, and F2 are some of the common keys to use for entering the CMOS setup utility.
CMOS Setup
To access the CMOS setup on an HP ProBook 4520s, restart the laptop and press the "Esc" key repeatedly as it boots up. When the Startup Menu appears, press "F10" to enter the BIOS setup. From there, you can navigate through the CMOS settings using the arrow keys. Be cautious when making changes, as this affects system configuration.
Use CMOS setup.
CMOS setup
CMOS settings are altered by the BIOS program while in setup mode.
Most computers have a keystroke (usually esc, del, or F12) that will interrupt the boot sequence when you start your computer. In the past, this would be when the white text flies across the screen displaying memory available, hard disk sizes, etc. This will get you into the BIOS for "cmos setup". CMOS is a type of memory that does not lose its data on power loss. In earlier computers, this is where the boot up configuration was stored; hence the phrase, "setup cmos"
