hi guys
I was wondering if there are anybooks one how to build your computer from scratch, like unique computer........ not x86 or PPC, just purely your own hardware.

or even anybooks on how exactly the x86 motherboard works.

This is unclear - do mean assembling your own PC from components you purchase, or are you asking how to build your own mobo, etc? If it's the former, a quick online search will reveal numerous Howto guides (although they aren't really necessary given that there typically are only 8 or 9 components to a PC, and they can only be connected one way). If it's the latter, I can't help you but good luck with it -- J.W.

Practically speaking building your own computer similar to a PC from scratch is not realistic. I would start small and build something using a 8 bit microprocessor. IMHO this will show you the fundamentals of more complex computers. One of the most enduring of the 8 bit micros is the Intel 8051.

do you have any Good web sites that you can provide me with?? and plus what kind of stuff can you do with 8 bit microprocessor??

A motherboard in a PC is a computer that was built by scratch from someone or the manufacture. The price of making a motherboard is very high because ATI, Intel, nVidia, SIS, VIA chipsets have to be bought by the thousands. Also the connectors (PCI, AGP, PCIe, DIMM, RIMM, parallel port, serial port, PS/2, USB, IEEE-1394, audio, digital audio, etc) have to be bought by thousands.

All computers have the basics like a processor, memory storage, input/output connectors, power supply. It does not change with size when using a motherboard or as small as finger nail.

You can use ARM, Microchip, Zilog, AMD, Intel, Motorola, PowerPC processors for the heart of your mini-computer. Then write software in assembler, C, C++, Pascal, or Basic to give your mini-computer brains to do whatever you want it to do.

A site like http://www.epanorama.net will give you more information.

Almost anything

yea but these are just microcontrollers?? aren't they?? and plus they don't really act like PC computers, as in you can't really just plug in a keyboard and a monitor so that you can type the code on to it

well you said you wanted to build from scratch, if you just want to plugin a keyboard and monitor, just buy a dell

Nope. They do not act like a PC computers.

Microcontrollers are mini-computers, so they can handle any device. You need to program them to understand a keyboard and to output information to a monitor.

The BIOS on a motherboard tells the processor how to handle keyboards, mouse, serial ports, parallel ports, etc. The manufacture already did the hard part to make the motherboard work the way it should work.
