identifying devices in the bios...

Does anyone know how to identify system devices in the bios?

I need to disable a faulty embedded video card and refer the system to an old card I have plugged into the pci.

Is the video card, onbard
if by on board you mean it cant be removed from the motherboard, then yes.
There should be a jumper on the motherboard to disable it.
There are several ways on-board video is handled. It could be disabled in the BIOS, by an on-board jumper, or automatically if it senses a video board installed in the AGP slot.
would the jumper be specifically for the video card or for the bios in general?

also what's the difference between pci and agp?

the pci slots are white typically, and they are what most of your devices plug into.

most new motherboards have a single brown agp slot that is staggered back a hair, and is usually the closest slot to your power supply. they look alot like a pci, but a tiny bit smaller.

there is sometimes a half slot for a modem closest to the supply, typically cream colored, dont confuse this tiny little slot with an agp slot.

there is also sometimes some isa slots on your mainboard, it is the old school long black double slot. these are almost always at the oppisite end of the case from the power supply.


here is a picture that will clear it up.

I dont have a specific jumper for my video or ethernet on my motherboard(it was custom built) but there is a jumper labeled "Bios write" and it has the two options of erase/program and protect which is the default.

would switching to erase/program allow the bios setup to actually configure the hardware?

i really dont think you want to do that.....

i think that is only supposed to be moved when you are trying to update your bios....

what exact brand and model of mainboard do you have?

and by the way

"I dont have a specific jumper for my video or ethernet on my motherboard(it was custom built)"

custom built wont change whether or not there is jumpers on the board, unless someone bought all the tiny peices and etched their own pc board, and actually fabricated your mainboard....
which i doubt highly....

many people are told their pc is "custom built"

in reality, it was custon configured.

the mainboard is still a mainboard that anyone can buy.
the hard disks are still hard disks anyone can buy.
the video card, it is probably made by nvidia, or something similar...

this isnt "custom"

go look at and you will see homemade frames, engines, and even seats and gas tanks. this is what the term custom really means. it means that they made you a computer that noone else has. it means that it was set up specifically tailored to your needs. usually to do this you meet with a consultant, and they try to figure out what your needs are...

then they make you one of twelve machines that they have parts already packaged for. and then they tell you it is custom.

if you consider a machine that was built by a private person or a small shop to be custom, then i think most of us at this forum have custom machines....
i wont buy an already assembled machine, not for more than 50 bucks....

I didnt think that a motherboard could be custom built but every hardware diagnostic I've ran on the system has told me the motherboard is an intel 440 and by looking at it I can tell that it definetley isnt. There is a labeled diagram of the motherboard taped on to the bottom of the chasi and like I said there isnt any thing labeled for the integrated periph.

I think maybe it would help if told the history of the machine:

the system I am trying to get functional was built to run a TR micropress(the absolute top of the line in printing equipment, these machines are used in nearly all print-for-pay buisnesses)

I came to own it because my father ran an office machines buisness. the computer itself was built for something like $10,000 and the actual printing/scanning/etc. equipment is worth nearly $90,000(we dont have these parts of the system anymore).

I dont know how much of the computer was custom built but I havent been able to find the motherboard anywhere and this is the first computer I have ever seen with five HD slots in the front and dual pentium III's.

the computer itself is a marvel and as soon as I find my digital camera I'll post some pics of it so you can see what I'm talking about.

Ive pretty much given up on getting the machine fully functioning because I have an obvious lack of knowledge and would probably render the thing completely broken before I could get even the video working(let alone configuring the processors right).

Much thanks for everbodies' help on this.

Do you get any video at all? Or does the monitor stay black when you turn on the machine?
foot in mouth

well, i have to take back what i said, your PC is most definately inside the realm of "custom" although, it was still maufactured by a corperation that most likely would have the info you require.

looking forward to seeing these pics though...

I would agree with bob vila in both instances....definition of a "custom built" PC is not all its hyped up to be but it kinda became a standard for describing the PC's that are not bought off the shelf but built for the customers need specifically. But what you describe there G_thompson would fall under a definition of a "custom"...I want to see those pics too...I would say this would be done trough the bios advanced settings..soemthing like onboard video enabled..... :D
