1.What is M2 support as it applies to data storage?

2. If I want to install a hard drive that is 2 Tera Bytes or larger, what do I need to do with my BIOS?

Answer 1

Question No 1: M2 data storage:

M.2 is a solid state storage which has a size of a USB. It is designed for more speed. M.2 is far more superior than other SSD's with smaller size SSD it occupy less space and provide more speed. M.2 SSD is stable and reliable

Question No 2: Installing a Hard Drive:

   There's no need to do anything in BIOS you can simply do it on your normal active pc this will recognize any size of hard drive and install it and if you are concerned with BIOS you must not make any change in your BIOS let it remain as it is as it was with old drive.

You may have issues when installing a hard drive there's a possibility that your PC may not recognize the hard drive or may not display the correct amount of disc space.
To correct this issue you have to search something called "DISK MANAGEMENT" on your pc. Her you can see your unrecognize hard drive here you can see your newly hard drive is portioned into 2 parts right click on the tag which says your drive name e.g "Drive D" and click on Convert to GPTDisk now partition has ended now you have a complete block of your memory now matter how size it is.
Now you have to make your drive active right click on the memory block and click on "New Simple Volume". Name the drive and then click on finish.
Now your computer recognize your drive
