Join Mike Meyers for an in-depth discussion in this video System setup, part of CompTIA A+ Exam Prep (220-901) Part 1: Core Processing.
- Not all of BIOS is absolutely fixed.…BIOS by its nature has to keep track of assumed hardware…that may change over time.…For example, it's going to keep track of your hard drives.…If you've got one, two, three hard drives,…and the capacity of those drives,…it's going to remember things like the boot order,…if you've got three drives,…which on you going to boot off of?…Or would you like to boot off your CD-ROM first?…So, if we have changeable aspects,…then we have to be able to get into the BIOS somehow…and make those changes.…
And the tool we use is the system setup,…sometimes known as a CMOS setup to us older guys.…Whatever the term, to get to your system setup,…you've got to watch your computer.…Boot your computer up and watch the screen carefully.…At a certain point you'll usually see something that says,…"Press DEL to run system setup."…or "Press F2", you have to press the button.…Usually you only have like a couple of seconds…and you hit the button, and poof!…You're magically transformed into the world…
The CompTIA A+ 220-901 exam is comprised of six key parts. The first, core processing, is covered by this course. Instructor Mike Meyers explains the fundamentals of PCs, microprocessors, RAM, and BIOS. He also shows you how to set up, connect, maintain, and troubleshoot the main components of a computer.
Note: The six courses designed for the CompTIA A+ (220-901) exam preparation include core processing, core hardware, peripherals and building a PC, displays and printers, networking, and laptops and mobile devices.
