You have probably have done this have you check to see if you have the latest bios. Also see if HP has anything on there website.  You are move advance then most of the people here the only thing I can do to help you out is bounce ideas off of you.  I don't have my network doing a network boot or anything like that.  I have some frineds that use centrix but they have a OS on the systems.  Good luck if you need to bounce idea off of someone imz me.

I have one of these.\nRAM is RAMBUS(proprietary) - it is expensive\nCPU is socket 423-pin(outdated) - maximum 423-pin is 2 GHz \nCheck this out though, for full upgrade compatibility\nhttp://www.powerleap.com/

Odds are you will need an adapter.\n\nIf I recall correctly, the 1.0 GHz chips were the last ones electrically compatible with the older boards.\n\nTo be honest, the odds are pretty good the the P3 actually benchmarks equally if not better.\n\nI'd test it before messing around with it.  Benchmark them with something like FreshDiagnose.

Compaq desktops are pretty standard these days allowing a variety of aftermarket devices to be installed and parts exchanged. I too remember when Compaq used a lot of strange ways to ensure that you could only repair or upgrade their equipment with Compaq branded spares.

I'm strated too. The x64 version has problems executing some 32-bit (and 16-bit) programs. That's why its mostly used on servers and not home computers?!

Just try and see if it works. You will probably have 512mb of RAM running at 233Mhz. If the speeds do not much then you were here several beeps when you start up your computer so you should know that something is wrong with your RAM. Different size doesn't matter but if you have a 512mb RAM module its better than having 2 256mb modules.

I know you said jumper settings are ok, but what position is the jumper set to on your new drive?  Looked on Compaq/HP and looks like it should be set to cable select.  Make sure to use the ide cable that was originally installed not the new one that came with your new driveas it is correct kind for cs.  New cable may not support cs may be master/slave type.  That may help.  \nSince you did not include what Evo I had to guess a little...\nhttp://h20000.www2.hp.com/bc/docs/support/UCR/SupportManual/TPM_287935_rev2_us/TPM_287935_rev2_us.pdf\nThe link should take you to a pdf about the EVO.  Click on Hard drive installation guidelines for more info.\n\nHope this helps.  If I told you things you already know, then my apologies; I just know that it is easy to over-look something this small when upgrading.

Many older Compaq Deskpro computers had a system partition on the first 30 megabytes (or so) of their hard drives.  It was used for BIOS configuration and provided a nice little GUI.  Your new computer may be detecting this system partition and trying to boot to it.\n\nTry booting to a DOS/Win95/Win98 floppy disk and running FDISK.  Make sure your operating system partition is set as the "active" partition.  If you still have problems, you may be able to simply delete it, but make sure you make a backup of your system first (Ghost is great for this stuff).

You can start by noting what type of slot/socket it has for the CPU, and/or any model numbers / designations to the mainboard, as well as the manufacturer. THEN perhaps we can look up something appropriate.

It probably means that you have four slots for RAM, but you must install them in pairs.\n\n2 x 2 = 4

Appears to be DDR Ram PC2100 nonECC\n\nhttp://dealnews.com/memory/prices/systems/Compaq-Presario-s4020-wm-PC2100-DDR-266-MHz/32284/128MB.html

the newer ones might - I have a couple computers from 2000 that don't though

1)Battery flat\n2)Bios/cmos setup not performed properly. (all hardware not registered.\n\nIf it's an older PC also check parity/non parity setting in bios. If your system requires parity, then non-parity DRAM will not work.

When Com 1 is being used most older computers share IRQs and only make the memory address different. Most of the time if COM 1 is in use then COM 3 is unavailable as it shares the same IRQ.  There are ways around this if need be but more information is needed.

Take your Compaq and either sell it or trap shoot it, then buy something with a SOYO board in it.  There is only one thing worse, and that is a Dell.  I have had several, and refurbished several and had nothing but problems with hundreds of them.\n\nWindows 2000 also is kind of unstable, especially in a Compaq.  It is like hiring two crackheads to work together!
