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.
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.

A sequence diagram in a Unified Modeling Language (UML) is a kind of interaction diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Sequence diagrams typically (but not always), are associated with use case realizations in the Logical View of the system under development.
A hard boot, or cold boot, involves turning on the power with the on/off switch, A soft boot, or warm boot, involves using the operating system to reboot.
A a soft boot takes the intials steps if a hard boot doesnt happen.. A hard boot initializes the processor and clears memory
How many additional devices can be assigned in the boot

The order of devices the computer looks at during booting may need to be changed. During the boot sequence, escape to the BIOS and see what order it is and change and save the configuration if necessary.
BIOS setup
A computer does not need to have any input or output devices plugged into it at all in order to boot, as long as it is configured to not stop on missing devices; the most common "stop error" for missing devices is a keyboard, and this can typically be disabled.
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.
