Hack #4. Boot Faster

Some of the stuff your computer does at boot time is of no use. Disable those features to boot faster.

The system BIOS does a lot of work in the P.O.S.T. phase before it gets your system to the point where it reads boot-up information from a disk drive to load an operating system. Some of the things that happen in P.O.S.T. have nothing to do with system performance other than impeding the process of getting to the operating system to run your applications. Intel, AMD, AMI, Award/Phoenix, and the PC manufacturers were aware of this waste of time, evaluated the events involved, and in many cases took steps to reduce the number of items and the amount of time the startup process takes. To that end there are a handful of changes you can make in order to boot up faster:

Disable Extended Tests

Many systems offer the option of allowing an in-depth test of system memory and components (an extended test) or zipping through the system and getting to bootup as quickly as possible. With RAM as reliable and economical as it is (and having so much of it) and having Plug and Play operating systems like Windows and, to some extent, current versions of Linux, the Quick Test mode is more than adequate, and preferred for faster boot times. This parameter is shown in Figure 1-4 and specifies the depth, and thus the time involved, for testing system RAM and finding and checking the basic components of the system—COM and LPT ports and such.
