Where can I get the Motherboard Setup Manual for a Compaq Professional Workstation AP550 Pentium III

Go HERE

According to the specs I have Serena, the eMachines eTower 633i Desktop PC, uses a TriGem Cognac motherboard.

[TriGem is the manufacturer, Cognac is the model.
Note it is Not the TriGem Cognac+ ]

Click on - Cognac - in the left side of the list.

Going back to the Motherboards.org page;
(Nothing like upside down photo information, and the motherboard is turned 90 degrees to the Right, to how it actually sits in your computer case )

The processor socket is a Socket 370,

http://en.wikipedia.org/wiki/Socket_370

Used for Intel Pentium III processors, and intel 'Celey' processors.

(Excuse me......Celeron.
An Intel Pentium III processor has TWICE the L2 cache, that a comparable Intel Celeron has.
The cache for a Processor is a small memory area for the Processor.

It is the First memory the Processor accesses.
The Ram Memory is second, and the Harddrive is third.
More cache for a Processor makes it more faster )

The motherboard chipset is an Intel 810.

The Northbridge chip of the motherboard chipset, is an Intel 82810.
The Southbridge chip is an Intel 82801AA, or an Intel 82801AB.
(Intel ICH, or Intel ICH0 )

Looking at the chart, and reading across, you can see what the Intel 810 motherboard chipset supports;

1) Processors: Intel Celeron, or Intel Pentium II, or Intel Pentium III.

2) Processor Front Side Bus: (FSB) 66MegaHertz, or 100MHz.

3) SDR Sdram ram memory at 100Megahertz.

[Single Data Rate Sdram is often just referred to as Sdram.

Erroneous.
Double Data Rate Sdram is also Sdram (DDR Sdram)
Synchronous Dynamic Random Access Memory
So is DDR2 Sdram, and DDR3 Sdram ]

Also referred to as PC100.

So when looking for a CPU you look for;

1) Fits in a Socket 370 processor socket.
Yep. The best is going to be an Intel Pentium III.

2) Has a FSB of 100MHz.

Hmmm,............

Scroll down.

Pentium III 1100.

Maximum frequency rate ('Speed') is 1.1GHz (1100MHz)
Front Side Bus = 100MHz
Uses a Socket 370 processor socket.
Part Number = RB80526PY005256
sSpec Number = SL5QW

256MegaByte of L2 cache. (256MB)

A comparable Celeron would have 128MB of L2 cache.

[ Don't forget to follow Anti-Static Precautions.
Clean the bottom of the Heatsink THOROUGHLY, and the top of the Processor if it needs it. (I always do anyway)

PROPERLY apply fresh, new Thermal Paste.

That's an old mainboard (Motherboard), used in a Compaq Presario 5716 desktop computer. (And perhaps a few other Compaq Presario's)

1) Uses a Slot 1 (Intel) processor slot.

http://en.wikipedia.org/wiki/Slot_1

2) Maximum Intel Slot 1 processor that can be used, is an Intel Pentium III, with a 100MegaHertz Front Side Bus. (100MHz FSB)
Maximum frequency rate for the processor is 700MHz.
('Speed')

http://www.cpu-world.com/CPUs/Pentium-III/TYPE-Pentium%20III%20%28Katmai%29.html

(Scroll the page down)

3) Ram memory is SDR Sdram at 100MHz. Or also known as PC-100. (168 pin. 82 on each side. Two Locating Notches on bottom. Commonly just known as Sdram, but that is a misnomer)

http://en.wikipedia.org/wiki/PC100

Maximum TOTAL Amount of ram memory is 384MegaByte.
Maximum Amount for each ram memory slot is 128MB.
There are 3 ram memory slots.

4) Do not know what the jumper settings on the motherboard are.

5) Do not know what the Front Panel header pinout is.

6) Can run Windows XP Home Edition, but do not expect a world of performance.

It will take up to a Intel Pentium III 1Ghz or Intel Celeron 1.1GHz CPU.

Here are the specs on the two Pentium III 1GHz chips:
the 100mhz FSB chip:

and the 133mhz FSB chip:

Here's the specs on the Celeron:
http://www.cpu-world.com/CPUs/Celeron/Intel-Celeron%201100%20-%20RB80526RY005128%20%28BX80526F1100128%29.html

>> Problem with the Compaq Pentium III, 450 MHz Processor
>> will not turn on

Try some other device in that AC outlet, to ensure that the outlet is working.

Look for any "master" on/off switch on the back, which may override the on/off switch on the front panel.

If the device is still under warranty, exercise the warranty to get it repaired/replaced.
Note that purchasing with some credit-cards "doubles" the manufacturer's warranty.

If the radio is worth more than $100, take it to a qualified technician, for professional trouble-shooting.

Sounds like the video card has quit. It may also have onboard video. I would try a new video card or try onboard video (if equipped). Good Luck

code 304 = Keyboard or system unit error. Not repairable. You will have to replace the system board.

hi im josh in cebu phils. it is very simple frnd. you try to install windoxs xp sp2 or sp3 so that you will not need to install driver for sound. or just get an update of your xp professional. good luck!

Oh, you can see it in the splash screen. The screen where the 'Compaq' logo shows up has the keys to what goes where. See the bottom of the screen.

See 'Setup' etc. If it doesn't show up (doesn't in mine, as my monitor starts late), then start it up and then reboot. The monitor doesn't switch off here. So, you can see it.

A pentium 3 processor is probably in a Socket 370 socket.

None of the current processors would fit in this socket, so you would want to look at second-hand computer stores / markets or maybe in your local classifieds.

It might be worth checking what speed processors your motherboard can support up too before buying one.
