System Boot Sequence
The system
BIOS is what starts the computer running when you turn it on. The following are the steps that a typical boot sequence involves. Of course this will vary by the manufacturer of your hardware, BIOS, etc., and especially by what peripherals you have in the PC. Here is what generally happens when you turn on your system power:
This process is called a "cold boot" (since the machine was off, or cold, when it started). A "warm boot" is the same thing except it occurs when the machine is rebooted using {Ctrl}+{Alt}+{Delete} or similar. In this case the POST is skipped and the boot process continues roughly at step 8 above.
You always want your boot order to point first to the device where your MBR/Bootloader is going to be. For 99.9999% of home users that is the first Hard Drive, and 99.9% of the time that is the device you want booted first. The other times you can go to BIOS and change it. (E.G. Installing an OS and needing to boot from the CD/DVD Drive, or trying a Linux LiveUSB Distribution) Second to the fallback device (Usually CD or Floppy) so that if your HDD is borked you can still boot the computer with a boot disk. Finally Network is kinda moot since that is not used outside of medium to large enterprise and enthusiast setups.
First, Second, Fourth, Third, Eighth, Seventh, Sixth, Fifth, Ninth, Tenth, etc, etc...
depends if you want to boot from a CD or from your hardrive

The boot sequence order of devices is the order in which your computer will boot its devices. You can usually choose from the hard-drive, the disk-drive, and a few more options.
AS DOS boot sequence is the series of steps your computer takes when it is turned on. Once the DOS boot sequence has been completed, the start up activities then go into action.

Preboot Sequence During startup, a Windows Server 2003-based computer initializes the boot portion of the hard disk and the preboot sequence begins. This sequence consists of four steps: • The computer runs power-on self test (POST) process to determine the amount of physical memory; and • The hardware components are present. • If the computer has a Plug and Play (BIOS), enumeration and configuration of hardware devices occurs. • The computer BIOS locates the boot device and loads and runs the master boot record (MBR). Note: Windows Server 2003 modifies the boot sector during installation so that Ntldr loads during system startup. Therefore you should disable the Boot Sector Virus Protection in your BIOS Setup.

When it finishes booting. (Starting Windows\Mac OSX\Linux\Other)
login screen appears turn computer on BIOS sceen loads desktop appears computer performs power-on self test
Reboot and press F12 (on my computer, at least) to enter the temporary boot sequence. Boot from the CD and then there you can make changes to the installation and then ultimately install the OS.
Are you referring to POST? That's the computer, pre-boot sequence called a "power-on self test."
