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” less than

eight seconds, that minimize hard drive startup delays.

• Select a CD-ROM 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.

3.9.2

BIOS Boot Optimizations

Use of the following BIOS Setup program settings reduces the POST execution time.
• In the Boot Menu, set the hard disk drive as the first boot device. As a result, the

POST does not first seek a diskette drive, which saves about one second from the
POST execution time.

• In the Peripheral Configuration submenu, disable the LAN device if it will not be

used. This can reduce up to four seconds of option ROM boot time.

NOTE

It is possible to optimize the boot process to the point where the system boots so
quickly that the Intel logo screen (or a custom logo splash screen) will not be seen.
Monitors and hard disk drives with minimum initialization times can also contribute to
a boot time that might be so fast that necessary logo screens and POST messages
cannot be seen.

This boot time may be so fast that some drives might be not be initialized at all. If
this condition should occur, it is possible to introduce a programmable delay ranging
from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced
Menu in the Drive Configuration Submenu of the BIOS Setup program).
