    I have a new Dell machine that came shipped with Win7 64bit and I need to dual boot it with XP Pro (either 32 or 64 bit, not sure yet, but it's dependent on some software that I need to run -- will find out soon). I have 2 questions:

    1) Do I need an OEM XP disc since its a dell machine? I was looking at this link (forums.mydigitallife.net/threads/17638-XP-Loader) on how to activate XP, and one guy said "alter the DMI string in the bios" and another said something about "OEM SLP". I'm fairly knowledgeable with computers, but I've never used that kind of activation before and some of these terms are new to me. Can someone point me in the right direction? Any suggestions/tutorials?

    2) If I alter the bios to activate OEM XP, will it affect the activation in the Win7 partition?

    TIA

    I would not alter your BIOS to activate XP. I would rather just use the XP OEM CD method found here. As your machine came shipped with W7, you will have SLIC 2.1 in your BIOS, dont want to mess with that.

    In my opinion you would be better to do a full clean install on your machine using XP OEM CD. Once this is done install W7 again, say on partition D:\ . As you have SLIC 2.1 already all you need to do is run Opa Tool or Windows Loader. Either one of these will insert a cert and key for you and bingo your activated and dual booting.

    Doing a clean install of XP, then reinstalling win7 is not an option as I already have Win7 set up with all the applications as I want it and I don't want to spend time to do it all over again.

    Why would I need to use a loader for the win7 installation if it is a legit installation?

    The loader is simply being used in order to insert a key and cert. You could do this via command line if you have the skills. You could also make a backup of your cert and key that is already on your machine using OEM Dump Tool. Then restore them post install.

    Either way I'm pretty sure your going to have to install XP to C:/ and W7 to D:/ . Which means a clean install

    Could I clone the win7 partition, then do a clean install of xp, and then restore the win7 partition to the D drive?

    I've not done it personally but it sounds feasible, although I imagine you would need to create a boot entry with say "Easy BCD".

    i don't think even if you make a so-called "OEM" XP disc it is going to be genuine and activated, but i could be wrong.

    it is my understanding that you don't have the same string in the bios like oem XP machines did since your new machine come with windows 7, so it will not work

    Would I need to backup the key/cert or will they be backed up when I clone the partition?

    Also, what's the problem with installing XP now without deleting the Win7 partition first?

    if you install xp on another partition now without deleting windows 7, you will only be able to boot into XP. if you install windows xp first, then install 7, 7's bootloader will automatically find windows xp and will adjust it appropriately so that you can boot into whichever one you want at startup.

    but you can go ahead and install xp now, but you will need a windows 7 install disc and you will have to do a startup repair. you will have to let it scan for each OS and then it will rebuild the bootloader appropriately. so you do not have to delete windows 7 and reinstall, but you can't do this without having a 7 install disc.

    but you don't even have to dual boot xp with 7, install vmware player and run xp in a virtual machine and you won't have to fool with any of this stuff, and in my opinion is the best way to do this unless you just want to absolutely have dual boot. i run with dual boot xp and 7 for a while, but just decided to use 7 alone if i need xp for anything i just do the virtual machine because it does not require me to restart/reboot whenever i want to use it.

    and, if you make an OEM XP install disc it's still not going to activate because your bios does not have the text/number string in it that corresponds to oem xp machines. it has slp for 7, which has nothing to do with xp from my understanding so do not even fool with this (unless someone proves otherwise). you will have to use antiwpa method of activation if you install for dual boot.

    but if you make an OEM XP disc, you can use it in vmware player by using oem bios mod for vmware player found here: http://forums.mydigitallife.net/threads/11152-VMware-Workstation-(Multi-Brand)-Bios-Installer just use the corresponding oem bios for which ever one you used on your disc. or you can use antiwpa in vmware player too, it's really up to you, one works just as well as another.

    Isn't the whole point of running the OEMBIOS TOOL?

    When I boot off the OEMBIOS TOOL boot cd, it gives me the option to check for Windows XP or Windows 2003. When I select Windows XP, it gives me 2 SLP strings (? not sure if thats what they are). This was the output:
    Code:
    Windows XP OEMBIOS Test v1.1/352/113
    F: Dell System OEMBIOS.CAT CRC=63875D1F
    F: Dell System OEMBIOS.CAT CRC=B6F0EEFD
    The above OEMBIOS set(s) should preactivate Windows XP on this system.
    Lines starting with E: are not reliably detected when running under Windows
    Does this not mean that if I use the tutorial alextheg posted and make an OEM XP CD with the Dell B6F0EEFD Bios files in the tutorial link, that it would activate fine?

    That being said, I thought about running VMWare, but the reason I need to install XP is because the computer is connected to a CNC machine and the USB adapter that connects to the CNC machine has problems with the Windows 7 drivers, and I wasn't sure if connecting through a virtual machine would cause other unforeseen issues.

    I guess it would be easier to test the virtual machine first and then if that doesnt work, try the dual-boot.

    well then it should activate just fine if you follow the tutorial on how to make the oem xp disc. sorry, it was my assumption that it wouldn't work the same, so my apologies. i didn't realize these same crc values would be in a machine that never came with xp in the first place--i learned something new today. again my apologies, just download the correct compressed omebios files for that crc then and follow all other instructions and you should be golden.

    as far as you running on CNC i have no idea what that is, but i wouldn't think that it would cause more problems but then again i really don't know. you could always test the vm first and see if it accomplishes what you need, that way you don't have to go through all the necessary steps of a lengthy dual boot setup process.

    If I go the Vmware route, will the OEM disc I make be sufficient to fully activate or will I still need to do the bios mod for vmware?

    btw, a CNC machine is router or basically a large machine with a drillbit attached to it that cuts various materials like wood, metal or in my case, plastic, based on instructions/paths sent to it from a computer.

    oh, yeah, now i know what you are talking about. i was thinking of some pc peripheral and i didn't know of any referred to as cnc lol. i don't see why it wouldn't work in the vm seeing as it will load usb devices just like if they are plugged in in windows xp, you just disconnect it from the host and it'll connect to the vm.

    if you make an OEM XP disc you will need to bios mod it with the tool i linked to with whatever bios matches the files you placed on the disc. this will activate it just fine. or you can just use whatever you already have (not make a new one) and use antiwpa in the vm. but an oem disc won't work correctly without the vm's bios modded. that tool is a very simple thing to use.

    Perfect ! Thanks!

    One more question. Yknow how the OEMBIOS tool gave me two BIOS strings? Do I have to get the OEMBIOS files for both of those CRCs? or is just one ok? The Dell (OEMBIOS.CAT CRC32=B6F0EEFD) was listed on forums.mydigitallife.net/threads/9795-The-Windows-XP-OEMBIOS-Archive, but the first one, 63875D1F, was not listed. Are the B6F0EEFD files all I need?

    either one of them should be just fine. if you can only find one set, get those--and it only takes one set as they both can't be added to the disc at the same time. the mediafire link may still be down for those, i'm not sure. try to download the B6F0EEFD and see. if you can't download them let me know and i'll post you a link to get those same ones because i have them for my laptop.

    and click thanks under my post if i've helped if you don't mind, you don't have to but i'd appreciate it. :cool:

    whats the diff between using a XP VL disk and XP Retail disc to make the OEM disc? Is the output the same?

    the output is the same but you have a different process for each version. in the "temp" folder that you downloaded from the tutorial post there should be two sets of folders in there, one is "VLK to OEM" and the other is "Retail to OEM"

    if you have a retail version you are converting you take the files from the "Retail to OEM" folder and put them in the i386 folder of your extracted image and "copy and replace". if you have a Volume license version you are converting you put the files from the "VLK to OEM" in the i386 folder of your extracted image and "copy and replace".

    i would also suggest to you that you edit the winnt.sif in to your liking as well and make sure you put the correct OEM key in it than the one that is already there. you can edit it in notepad. check your pm.

    Thanks stayboogy! Much appreciated. One last question. I'm looking for an untouched ISO for XP Pro x64 -- is there an iso with SP3 from MS? All I found was one with no service packs and a VL iso with SP2. Just curious.

    to be honest, i do not know. i'm willing to say there is one, but where you can find i do not know.

    but you don't have to use x64 version. if you aren't going to be allowing your vm to use more than 3gb of ram (which is way more than necessary) you don't need x64 XP. you really don't need x64 XP if you are dual booting either, unless you use more than 4gb of ram (which again is not necessary anyway, you can run XP just fine at the 3gb limit).

    just because you have x64 version windows on your machine does not mean that your machine requires x64 windows. as far as i'm aware, you and everyone else can use x86. the only problem with x86 is the ram limitation, that's the main difference in the two versions. supposedly x64 is more secure virus wise, but this is merely subjective because there are plenty of 64 bit viruses in the world...

    i would just install the Pro VL SP3 x86 version myself, even if you have enough ram to give it more than 3gb in the vm. get x86 Pro VLK SP3 from here: http://forums.mydigitallife.net/threads/26911-The-Windows-XP-Repository it's the very first link--it's clean and trusted i have downloaded and used it myself.

    sorry it took so long to respond. hope this helps

    You're right about using 32bit in VMWare, but I would have to disagree with you about 32bit for dual booting (in my case at least). If I was going to dual boot, I would probably use the 64bit because the machine has 8gb of ram and it would be a huge waste to NOT use it. I use a lot of 3D and CAD apps which can be processor intensive and would greatly benefit from a 64bit OS with full use of ram.

    That being said, I would ONLY use them in XP if I was dual booting. Since I'm going to try VMWare, I'm only going to load the application that communicates with the CNC in XP, so you're right, I don't need 64bit for that.
