You can't "enter" your BIOS without rebooting. However, BIOS settings can be changed during runtime. It very much depends on the BIOS you are running. Have a look here: http://stackoverflow.com/questions/6259124/apis-for-querying-and-setting-bios-properties for more information.
Also, a lot of what you might want to change is exported to /proc and/or /sys ...

Your first actions should be to find the bad stick(s) as doing anything further until the stick(s) are removed would be counterproductive until the ram runs error free.
I would suggest pulling all sticks and then test each individualy with what you used (Memtest86+) and get the probelm stick(s) out of the picture and then address the 32 bit OS limitations.

Not really. Your BIOS probably does not support GPT so it can't recognize the large drive. BTW, the drive will have 4k sectors and the bios/OS is seeing them as 512k. Sucks a bit. Depending on your drive there might be a jumper which lets it pretend to be a 2TB drive, but older systems can't see disks with > 2.2TB.

No. The BIOS has to support the specific processor model and stepping.
There are also hardware requirements that the motherboard might not meet. For example, the power supply on the motherboard might not be able to support the power a higher-end CPU requires. Laptops shipped with higher-end CPUs might ship with different cooling systems.
Usually, if the ...

What you describe sounds exactly like an SSD failure. I have seen this 3 times before in the last couple of years. All 3 happened the same way.
When a Hard Disk goes, sometimes you get intermittent functionality, a clunking sound to indicate imminent failure, etc. When an SSD goes, there's no warning. Just, gone!
I hate to be the bearer of bad news, ...

The amount of memory in your system depends on several things. First, the processor has to be able to address 64-bit memory space. Second, the chipset on your motherboard has to be 64-bit AND be designed to support 4GB or more as well. Third, your Operating System has to be 64-bit OR utilize PAE to address more than 4GB of memory (Windows 2003 server 32-bit ...

You need to ensure that USB Wake Up from S3 is set to Enabled and Power On By Keyboard is set to Any Key. These are under Power Management Setup:
Note, image shows Power On By Keyboard as Disabled, and you want it Enabled.
If your system is configured as per the defaults (like the above image), then your cat can wake your system when it is suspended, but ...

As you correctly stated, you will require a UEFI BIOS to use the GPT partition scheme on Windows.
The only way that you can install Windows on your 3TB drive with your current hardware is to format the disk using MBR and use two partitions for your data - my suggestion is 200GB for your O/S and applications, then split the remaining space depending on how ...

The EFI Shell is a "shell" (think of a command prompt or a terminal shell) that a (U)EFI "BIOS" can directly boot into (instead of your OS) allowing control and scripting of many items including booting scenarios,
Installing an EFI shell in an "EFI System" partition (type EF00) formatted with a vfat file system and properly named - "shellx64.efi" for a 64 ...

It depends on a few things. For starters on the OS.
If you boot DOS (ancient, I know) then DOS will do most of its jobs via BIOS calls.
If you use a modern OS then that will generally take over control from the BIOS.
Secondly, do you consider ACPI part of the BIOS?
That part keeps on running even after a modern OS is loaded).

As you know, a 32-bit OS won't recognize more than 3.25GB of RAM, because that's all it can address, while a 64-bit OS doesn't have the same problem. Between the fact that a 64-bit Linux isn't seeing all of the RAM, and the errors from Memtest86+, I'd tend to suspect you've got some bad RAM in the machine -- if one of the 2GB and one of the 1GB sticks are ...

Solution
The problem is only peripherally related to booting. It turns out that the issue is with the settings under Boot⇨Security Settings.
What happens is that if you change the User Access Level setting from Full Access to anything else (i.e., lower), then the BIOS does not show the prompt or accept the boot-selection key.
This seems bizarre, but has a ...

Asus suggest these steps on their webpage:
Insert CD into the optical drive. Your Notebook PC needs to be powered ON.
Restart the laptop. Press ESC when you see ASUS logo and then select the optical drive (may be labeled as "CD/DVD") from ODD. Press
Enter to boot from the CD.

I have a ThinkPad X230, so the keys may be different, but I have a few ways to get into the BIOS:
Press F1 at the Lenovo/ThinkPad logo to enter the BIOS.
Press Enter at the Lenovo/ThinkPad logo. The Startup Interrupt Menu will appear. Press F1 to enter the BIOS.
Press F12 at the Lenovo/ThinkPad logo. A tabbed menu will appear. Press Tab to switch from ...

Why are you trying to boot into an OS installation before you verify that the new RAM works correctly? That's a recipe for disaster and is likely to corrupt your OS installation. Do not make any attempt to load Windows until you know your hardware is reliable.
Test with memtest86+.

One way to reset your password in to remove the CMOS battery for a few minutes and then put it back again.
Don't do this unless you know exactly how to do this with your laptop. Doing this yourself might also void the warranty.
If your laptop is still covered under warranty, it would be better to have an authorized technician do this for you.

I eventually got it to work by going into the security menu of the BIOS and setting the following:
Secure Boot: Disable
Legacy support: Enable
Other notes:
I had already disabled the "Secure Boot" option in order to install Linux.
There was a scary red warning box that told me that these settings only affect Windows 8.
I do not know if this solution is ...

First, you should verify F12 is really your boot selection key. The boot selection key is different for each computer manufacturer and sometimes is different between specific models. Also, generally you shouldn't just hold down the boot selection key. You simply need to press it at the right time. By holding it down, you may inadvertently be canceling the ...

I did a quick search and found nothing definitive. The CPU supports it but the motherboard or BIOS may not.
You can download CPU-Z to at least confirm the CPU supports it
My guess is if there is not an option in the BIOS you are out of luck. Your best bet might be to contact the vendors tech support and see what they say.
