BIOS stands for Basic Input Output System. It is the most basic communication between the user and the hardware. The BIOS used in the Rack iPC is produced by Schneider Electric.
The BIOS Setup Utility lets you modify basic system configuration settings. These settings are stored in CMOS and in an EEPROM (as a backup).
BIOS is immediately activated when switching on the power supply of the Rack iPC or pressing the power button. The system checks if the setup data from the EEPROM is valid. If the data is valid, then it is transferred to CMOS. If the data is not valid, then the CMOS data is checked for validity. A message appears if the CMOS data contains anomalies, but you can continue the boot procedure by pressing the [F1] key.
NOTE: To prevent the message from appearing at each restart, open the BIOS setup by pressing the [DEL] key and save the settings again.
BIOS reads the system configuration information in CMOS RAM, checks the system, and configures it using the Power On Self Test (POST).
When these preliminaries are complete, the BIOS boots the operating system from the data storage devices available (hard drive, floppy drive, and so on). The BIOS launches the operating system and hands over the control of system operations to the operating system.
For enter BIOS setup, press DEL or F2 key after the Rack iPC has been initialized.
The following keys are enabled during the POST:
|
Key |
Function |
|---|---|
|
DEL |
Enters the BIOS setup menu |
|
F12 |
Using the [F12] key, you can boot from the network. |
|
F11 |
Displays the Main boot menu, which lists all bootable devices that are connected to the system. Use the up cursor ↑ and down cursor ↓ and then press the [Enter] key to select the boot device. |
|
Pause |
Pressing the [Pause] key stops the POST. Press any other key to resume the POST. |
NOTE: Keys input from the USB keyboard is only registered after the USB controller has been initialized.
