I really want to know on how to enable my hyperthreading and install a second Cpu

I am having some trouble because I have like no idea on how to enable my hyperthreading or install my second cpu. But I already set my ACPI to Multiprocessor in my Device Manager, but that didn't help for me at all. And I only have 1 Cpu graph showing in my Task Manager right now. But what I really want is 2 Cpu graphs to show up in my task manager a lot! I also tried to edit my bootloader, but it didn't work for me at all. My computer is a Dell Dimension 4600 with a Pentium 4 processor. And the gigahertz speed of it is about 2.80. But my Pentium 4 processor is not that new. It is older. So what I am thinking is that it may not support hyperthreading. I actually looked up these Pentium 4 processors on the Intel site, and it said that the 3.06 Gigahertz Pentium 4 processors support hyperthreading technology. It said that right on the box of the processor. And then the 2.80 gigahertz Pentium 4 processor said that there was no hyperthreading technology support on this box. I bet because it is older than the 3.06 gigahertz one. Oh well. But I found out that there are 2 kinds of Pentium 4 processors which are 2.80 gigahertz. And one said it supports hyperthreading technology. And the other Pentium 4 said it did not have hyperthreading technology. And I also noticed that the FSB number was different too. That was probably why it has hyperthreading. But all I am saying is that I hope my computer has hyperthreading technology support. I think that it might have it for sure, but the problem is that I cannot seem to install the second Cpu or to enable my hyperthreading.
And my bios is really old and outdated too! It says that my bios is like from 2004. And that's not good at all. And I do not even have a hyperthreading technology option in my bios to enable or disable it. Now that is really bad! I am so upset with this. But I looked up my computer online which was Dell Dimension 4600, and it said it came with hyperthreading technology support. So why can't I get the second Cpu graph to show up in my Task Manager for? Because I only have one 1 cpu graph. And I really want 2 cpu graphs! So please help me out here on this awful situation that I am in, and please guide me through this so that I can enable my hyperthreading and install my second cpu. Because I looked up my computer and it said that is has hyperthreading technology. So I am really sure that is correct. I am so upset and frustrated about this. So what should I really put into my bootloader? So just explain to me on what to put into my bootloader so that I can finally see 2 Cpu graphs in my Task Manager. Then I will be much happier, that's for sure. :mrgreen:



Now, last but not least, I have no idea on how to flash my bios at all. I have a Dell Dimension 4600 with Windows XP Professional and Service Pack 2. And I have like no idea on how to flash my bios. I really have not the slightest clue on how to do it. So please help me out here on this problem that I am having. Because I really need a new bios because my bios is really old and my bios date is from 8/26/04, I believe. And that is just way to outdated for me which is not good. Also, I tried to go from my ACPI Uniprocessor to Multiprocessor but that did not do a thing to help. Like in my Task Manager it just shows 1 Cpu graph which is not good at all. I mean it should show at least 2 Cpu graphs. So I want to know why my Cpu graph is still showing 1 graph. Oh well. But when I update my computer driver to ACPI Multiprocessor, it should show at least 2 graphs! I mean something is not going right here. That is why probably because my bios needs to be flashed and upgraded to a different one, that's for sure. And also, I do not even have a hyperthreading option in my bios. Man, my bios is really old and not good. But what I am thinking is that when I change to Multiprocessor and enable my hyperthreading, I will see 2 Pentium 4 processors listed in my Device Manager. That would be cool. And I really want my upgraded bios as soon as possible! So I will be waiting for my response back from you very soon! I broke up my letter here in paragraphs so that it is much easier for you to understand and read it better. Sorry about the long letter, but I am trying to make a point here. :idea:
