The most recent version of HPUX I used was HPUX 11i v3, also known as HPUX 11.31. However, I cannot provide information on any newer releases or editions that may have occurred since then. It is recommended to visit the official website or consult with HP representatives for the most up-to-date details on the HPUX operating system.
The boot block of any OS contains the initial loading sequence of the Operating System. It starts the process of bringing into memory the first part of the Operating System which in turn brings the rest of it in for the entire boot process. This is known as bootstrapping the Operating System.
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.
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.
On MS platforms, the system partition is used to hold the boot files. The boot partition holds all the windows operating system files. Leave it to Microsuck to mis-lable the partition hiearchy. The system partition holds what is loaded and executed first after the computer runs through its preliminary BIOS boot sequence. It tells the computer where to start loading the operating system from; the boot partition. The boot partition is where all the program files (thousands of them) needed by the operating system are stored. If the system partition is deleted; the computer will not find the operating system. If the boot partition is deleted, again; the computer will not find the operating system.
BIOS
the it was not cool
The computer starts but will not do anything useful. The Operating System is what creates any user interface. when you start up your PC in your BIOS there is a boot sequence normally it will check for something to boot from out of the HD first (in some cases it will look at the floppy drive first...usually on really old machines) if it doesn't find anything in the Hard Drive(aka your OS) it will follow the boot sequence until it finds something to boot from if it doesn't find anything to boot from (such as a live CD) then it will display something along the lines of "error: boot device not found"...i hope that answers your question (by the way you can change the boot seq in your BIOs if you were thinking about installing a new OS)
