Question 1: A new person has just been hired. You need to install a new Linux-only machine for them, configure it with their user information, and integrate it into the LAN such that they have access to the services necessary to complete their work.

| Question 2: While assembling the machine, what considerations specific to Linux installations must be kept in mind? |
|
No machine can have more than two IDE drives installed. |
|
Disable Plug and Play features when jumpers are available to do so. |
|
If you were not the one choosing the hardware, be sure any modems involved are Winmodems. |

|
Be sure that all cards are firmly seated. |
|
| Question 3: Once the machine is assembled, what BIOS adjustments need to be made in modern machines before attempting the installation? |

|
Disable the Automode serial port setting, which automatically assigns COM ports to serial ports. |
