hardware power up order

[bassfisher6522]

I was just wondering is the an order for a PC hardware to power up/on? If so were does one find that at. The last thing to power up is my GPU, is there a way to change it to make it the first thing to power up/on.

Don't know whether this is what you're after, but I would have thought the basic startup procedure for any computer is pretty much set in stone:





"Although there are differences in how each computer actually starts, they all share these basic steps. This example is particularly directed towards Dos and Windows (except where noted).

• The computer performs a test on itself to make sure all components are available and ready. One important part of the first steps is that the registers (the place where data and instructors go in the CPU to be processed) are cleared of any old code. This is the start of the Power-On Self Test or POST test.
• The CPU then gets a memory address from the ROM which where to find the ROM BIOS in order to continue the check.
• The CPU now sends signals on its system bus, the main circuit on the mother board to which all components are attached.
• The clock is checked by the CPU. All computer functions are regulated by this clock, which sends an impulse at a regular interval. It is very much similar to the beating of a bass drum to mark time in music.
• POST tests the memory chips on the video adapter and loads information from the video adapter’s own BIOS into the system BIOS. Sometimes the BIOS codes from slower CMOS are also loaded into RAM. Newer PCs have additional equipment which also have their own BIOS on their own cards. These items, called plug and play also get loaded into the system BIOS.
• The CPU now checks to see if a keyboard is attached, if it is working correctly and if any keys are pressed. Many operating systems permit the user to interrupt the POST test to change the computer’s initial or default behaviors (or environmental variables).
• POST now checks the paths on the bus to the floppy and hard drives (and other devices) to see what storage and peripheral devices are available.
• Once all the components contribute information to the system BIOS and all other checks have been performed, if the test indicates a problem, such as a corrupted FAT table, the test will inform you and usually offer a change to fix the problem via a setup screen. If there are no problems, the operating system will display some form of greeting: on a Windows machine, you see a large Microsoft logo. On a Macintosh, you’ll read "Welcome to Macintosh." Command-line systems, such as Unix, may show nothing but a prompt."

No not really, and I all ready a grasp of, but informative none the less. Thanks for the input.

You're welcome, sorry I was barking up the wrong tree.

With a bit of luck, someone else will have some answers.
