Re: diagram of motherboard wanted
Based on your post/description, you would want to do 2 things: 1) upgrade a Cyrix and 2) install LAN capability.
#2 is easier, all you need is a PCI LAN card with the right drivers for your operating system and you should be set to go;
#1 is trickier... If you are referring to a Cyrix MediaGXm motherboard, at most that you can go up to is a 300 MHz CPU and hopefully a max of 256Mb of memory depending on the motherboard version.
If you are referring to a Cyrix MII-433 processor which ran at 300 MHz (100x3), hopefully you can try replacing the processor with an AMD K6-2 500 or higher, that is of course assuming that the motherboard is compatible (FSB, VCore voltage, multiplier). You should take into consideration that other than the MII-433. most Cyrix CPUs run at 83 MHz bus in a (Super) Socket 7 motherboard and technically is extremely overclocked (PCI bus running at 41.5 MHz). You should meticulously check the various jumper settings to accommodate your upgrade CPU. For stability, perhaps you should choose an Intel 266 with MMX, for speed AMD K6-2 500. This is of course if you can still locate such processors and appropriate memories.

Some RJ 45 jack cable has fault so try with another RJ 45 jack cable ..
Purchase new rj 45 jack cable from nearest computer shop.
There must be 2 port on modem 1 for ADSL phone line cable and otthr for LAN ethernet port means RJ 45 jack port.
Try with another rj 45 jack cable it should be connect.Make sure that LAN port of modem is not faulty means make sure pins on that port are not break.
Let me know if you need further assistance.
Thanks for using FixYa.
These ports are soldered onto the motherboard. They can be changed out by a tech that has the right equipment. I have been able to successfully pull these off at one time using a heat gun set to high for 15 seconds. Then the solder points need to be cleaned thoroughly and the new jack placed into the brass sleeves of the motherboard and each leg soldered into position.
You are probably looking at a RJ-11, used for telephone (dial up - modem). You are trying to put a RJ-45 connector in it.
The RJ-45 should have 8 wires while the RJ-11 may have as many as 6 connectors.
Thank you for your voluntary work with this organization.
Note: If you were to plug a RJ-11 into a RJ-45 port and if it happened that you plugged the other end of the phone cord (RJ-11) into a phone jack --- and the phone were to ring ... you would be pumping 60 volts into your computer. Be very careful with these connections. You would then need butter and jelly for your toast, which is what your computer would be.
Ok - recap: Both look very similar ...
Ethernet = 8 conductors - RJ-45
Telephone = up to 6 wires (may be 2 or 4 also) - RJ-11. NOT interchangable.
So how will you connect? If the laptop is not builltin wireless, you can get a PCMIA card for the slot on the side that will allow wireless or ethernet. Get the card at your computer store. ... Or ... use the built in modem for dialup., You would of course need a dialup account somewhere.

dear ashprabha, you are saying that your motherboard doesn't have a on board Ethernet slot. now, if u want to connect to internet means then you have to purchase and fix a PCI Ethernet card. so that you can connect to internet.
If your motherboard's ethernet (RJ-45) port is the only problem, you have two options. For a workaround, use a spare PCI or PCI-Express slot and add a network card. Assuming their is nothing wrong further down the line than the port itself, that should get you back on the web / home network.
If however, you do not have a (spare) slot to add a network card, the only alternative is repair. Most manufacturers are good about helping customers with repairs, though of course, at a cost. Even worse with RMAs is the shipping cost, which is often completely billed to you, both ways. For this reason, motherboards are usually cheaper to replace than repair.
Desoldering the RJ-45/USB module from your motherboard may seem like a simple task, but the average joe with a soldering kit simply doesn't have the ability to do this sort of repair without further causing further damage to the board. Leave the repairs to the professionals. If you are trained to do this sort of work, you shouldn't need any advice about how its done.
Install infrared module onto IrDA connector, and enable function from the BIOS setup. Make sure you have the correct orientation when you plug into the motherboard.
Towards rear of motherboard, next to first PCI slot, on AGP side. The number one pin is closest to rear of board.
Please let us know how this works for you, and if we can help you in any other way.
