Booting Without Attached Devices

For use in embedded applications, the BIOS has been designed so that, after passing
the POST, the operating system loader is invoked even if the following devices are not
present:
• Video adapter
• Keyboard
• Mouse
3.8.4

Changing the Default Boot Device During POST

Pressing the <F10> key during POST causes a boot device menu to be displayed. This
menu displays the list of available boot devices (as set in the BIOS setup program's
Boot Device Priority Submenu). Table 35 lists the boot device menu options.

Adjusting Boot Speed

These factors affect system boot speed:
• Selecting and configuring peripherals properly
• Optimized BIOS boot parameters
3.9.1

Peripheral Selection and Configuration

The following techniques help improve system boot speed:
• Choose a hard drive with parameters such as "power-up to data ready" in less than
eight seconds that minimizes hard drive startup delays.
• Select an optical drive with a fast initialization rate. This rate can influence POST
execution time.
• Eliminate unnecessary add-in adapter features, such as logo displays, screen
repaints, or mode changes in POST. These features may add time to the boot
process.
• Try different monitors. Some monitors initialize and communicate with the BIOS
more quickly, which enables the system to boot more quickly.
