What is TPM and what does it stand for? |
Trusted Planform Module acts as a secure cryptoprocessor. AKA a hardware platform for acceleration of cryptographic functions and the secure storage of associated information. Can be a small circuit board plugged into the motherboard or built directly into the chipset The specification for the TPM is published by Trusted Computing Group. |
|
|
What is a device driver? |
It is a file stored on the PC's HD that contains all the commands necessary to talk to whatever device it was written to support. All operating systems employ a method of loading these device drives into RAM every time the system boots. |
|
|
What is the Bootstrap loader? |
Is a little more than a few dozen lines of BIOS code tacked to the end of the POST program. Its job is to find the OS. it reads the CMOS information to tell it where to look first for an OS. |
|
|
What is PXE and what does it stand for? |
Preboot execution environment. This enables you to boot a PC w/o any local storage by retrieving an OS from a server over a network. |
|
|

Jill decided to add a second hard drive to her computer. Shethinks she has it physically installed correctly, but it doesn’t show up inWindows. Which of the following options will most likely lead Jill where sheneeds to go to resolve the issue? A) Reboot the computer and press the f key on the keyboardtwice. This signals that the computer has two hard disk drives. B) Reboot the computer and watch for instructions to enterthe CMOS setup utility (for example, a message may say to press the deletekey). Do what it says to go into CMOS setup. C) In Windows, press the delete key twice to enter the CMOSsetup utility. D) In Windows, go to Start | Run and type hard drive. ClickOK to open the Hard Drive Setup Wizard. |
B) Reboot the computer and watch for instructions to enter the CMOS setup utility (for example, a message may say to press the delete key). Do what it says to go into CMOS setup. |

What’s themost likely explanation? A) The device doesn’t need BIOS, so there’s no need for adriver disc. B) The device has an option ROM that loads BIOS, so there’sno need for a driver disc. C) Windows supports TV capture cards out of the box, sothere’s no need for a driver disc. D) The manufacturer made a mistake and didn’t includeeverything needed to set up the device. |

That’ll clear theCMOS and get you up and running. B) Open up the computer and find the CMOS clear jumper.Remove a shunt from somewhere on the motherboard and put it on the CMOS clearjumper. Reboot and then put the shunt back where you got it. Reboot, and youshould be up and running in no time. C) Boot into the CMOS setup program and then find the optionto load a plug- and-play operating system. Make sure it’s set to On. Save andexit CMOS; boot normally into Windows.
