Patch Vista’s Kernel to Address more than 4 GB of Donate 23 Entries (RSS) JUN Memory Author: Remko Weijnen Comments (RSS)
Blogroll As you may know the 32 bit, also called x86, editions of Windows Profile Vista cannot address more than 4 GB of memory. You may think this Andrew Morgan 4 GB is a limit of the processor but this isn’t true; using Physical Arnout’s blog Address Extension (PAE) it’s possible to address more memory Assa’s Blog Barry Schiffer Enterprise Server versions of Windows (2003 and 2008) can already Delphi Praxis Ingmar Verheij address more than 4 GB of memory so why can we not do that with Jedi Api Blog Vista? The answer is: Microsoft doesn’t want that! It is all just a Jedi API Library licensing matter, we can see this in the registry. Take RegEdit and Jeroen Tielen goto HKLM\CurrentControlSet\Control\ProductOptions and Kees Baggerman doubleclick the Value ProductPolicy, scroll down a little until you see the value “Kernel-PhysicalMemoryAllowedx86”, next to it is the value Categories 01 00 which corresponds to 4096 (1000 is the Hex of 4096): .NET (3) Top Posts Active Directory (28) Altiris (36) App-V (1) Update AMD Display Driver under Apple (5) BootCamp Application Compatibility RNS 315: Enable the hidden (11) bluetooth carkit Automotive (5) Default username password HP BootCamp (1) Storageworks P2000 C# (5) Query Active Directory from Excel C++ (2) Patch Windows 2008 Terminal Server Citrix (86) to allow more than 2 concurrent Delphi (60) sessions Embedded (4) Trick to Export Private Key from Exchange (16) We can also see where this (and other licensing values) come from: Certificate Request General (71) if we look in %systemroot%\system32\licensing\ppdlic al license How rdp passwords are encrypted iPhone (5) values are in XML files.

Does this work on windows 7?
Remko 2 June 24th, 2009 at 22:45
I didn’t test it on Windows 7 but it’s likely to work if the bytes match (if dUP2 accepts the 7 kernel because the byte pattern is found then you should try it).
lector 3 June 25th, 2009 at 8:46
sounds interesting, although i never had vista installed for more than a day. but maybe for Windows 7 this could prove useful =)
found a little typo: “next to it is the value 01 00 which corresponds to 4096 (1000 is the Hex of 4096):” 01 00 10 00
lector
Remko 4 June 26th, 2009 at 14:00
@lector: actually the value is a DWORD so (as Geoff also pointed out) the value includes the 00 before and the 00 after the marked area.

Why not using 64 bits edition of Vista directly? I’m having Vista x64 edition installed on my laptop and I can see 4Gigs of RAM direcly without patching.
My 32 bits applications are working too (like Office 2007, or VMware Workstation etc….)
Cheers Vladan
daNIL 9 June 29th, 2009 at 17:10
Vladan,
Using x64 versions restricts you to use only singed drivers, and can have some compatibility issues with native or low/level x86 application. But, in general, using x64 versions is of course a preferrable choice.

A Russian origin patch enabling 4Gb usable on Windows 7 x86. Just press “Разблокировать” button, and then Yes, and will proceed automatic restart. If you don’t like the patch, you can uninstall it (or edit) by viziting menu START > MSCONFIG > and then booting options. Or via EasyBCD. The pacth just adds an alternative boot option with modified kernel supporting full 4Gb RAM support with PAE enabled. See what is PAE in the archive. P.S. No viruses inside, you can check by any antivirus software.

Hi Klimax,
You’ll be able to get 4GB (or even more – you can use up to 64 GB in x86) of usable memory ONLY if your motherboard supports memory remapping feature. “x86 cannot address more then 4GB.” – this is completely wrong. As i remember, from Pentium or maybe Pentium pro processor can address up to 2^36 = 64 GB of physical memory in PAE mode, so the only thing which is needed – is OS support. Windows 2000 (server version) can support more than 4 Gb of physical memory (http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx) – and Windows 2000 Professional cannot. Why? The only difference is in licensing. If you patch Windows 2000 kernel, it will allow you to use all of your physical memory.
Also please note that all processes are using virtual memory, not physical. Yes, even if you have got 8 GB of physical memory installed, EACH process can still access only 2 GB of virtual memory (or 3 if you boot with /3GB switch). But you can run 4 processes and each of them will be able to access 2 GB of virtual memory, giving you utilization of 8 Gb of physical memory.
In case you’re still doubting, you can boot your windows with /nolowmem parameter (http://msdn.microsoft.com/en- us/library/ms791499.aspx), which restricts windows from using the lower 4GB of physical memory and test your system. However, at least, in Windows XP/2003, you must have 5 GB or more (or patch kernel ) to successfully execute this switch.

Paren,
There is almost no reason; however, drivers’ support for x64 is much lower than for for x86, some low-level applications will not work, so if you have old hard and/or software, you should test all of your needed apps and hardware to work correctly with x64 OS before moving.

Thanks Remko, it took me some time to fully understand what needs to be done and I read yours and Geoff Chappell’s article several times. One must really point out that a copy of the file is needed and the safest way is to create a new bcd profile via bcdedit. I will test it for some time and I might even consider adding more memory, so I can run a virtal machine without a fear of performance issues Geoff and Remko, nice work.

To those who are asking for an XP patch: Unfortunately the way the HAL was changed in XP SP2 would make a simple XP patch impossible. Read the section “Windows XP SP2” of Geoff Chappell’s article.

1. Look for C:\WINDOWS\SYSTEM32\NTKRNLPA.EXE
Original : BB 00 00 10 00 33 FF 6A 07 8B F0 Modify To : BB 00 00 40 00 33 FF 6A 07 8B F0
2. Save the modified kernel as mykernel.exe, put it under C:\WINDOWS\SYSTEM32\
3. Open C:\BOOT.INI
Copy and paste your original boot option, but add /PAE /KERNEL=mykernel.exe
example: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP SP3 OVER 4G” /fastdetect /usepmtimer /NoExecute=OptOut /PAE /KERNEL=mykernel.exe

XP patch is a more difficult task to do, as not only ntoskrnl should be patched, hal.dll also has problems with using it. Of course, you can use hal.dll from XP SP1, but it produces much incompatibility as well.

daNIL!
Thanks for answer! Well… I did it and XP SP3 can see all my 6 GB of RAM. All works really faster… Unfortunately i have many diff. problems with USB devices (pendrives and external usb hdd). I guess maybe we could use usbstor.sys from server 2003 or so (http://support.microsoft.com/kb/873402/EN-US) as well as other files needed to proper work of hex fixed XP SP3.
How looks hal.dll issues? I can made tests. I did not noticed more problems than with usb.
Hex trick is mentioned only on chineese sites till now – so not many infos. I found somewhere that using Gavotte Ramdisk fixing USB problems but can’t find this chinese site anymore (opera tabs gone when using portable Opera from… USB HDD).
IMO this hex way is worth to give it a try as looks till now very promising, and I hope USB problems may be fixed by using server drivers.

It is me again. Unfortunately hal.dll from XP SP1 not work at all (freez during boot), same problems with hal.dll from Windows Server 2003 SP2 (msg about missing dll during boot).
So – just re-change hal.dll will not work. I do not use USB mouse/keyboard – so it is not problem, but need to use pendrives and ext. USB HDD. So if someone is reading this – please give me some more ideas.
Maybe someone knows what (techincaly) is making such issues with USB drives? And why it is not problem for other 32bit systems with more than 4GB of RAM (like Windows Server 2003)?
daNIL 67 April 27th, 2011 at 12:26
Hi quay,
Are you sure you’re using the correct hal.dll? There are many versions of them, to detect the correct one you need to open your original hal.dll in explorer (rightclick-properties) and look for the original name. https://web.archive.org/web/20170827160655/https://www.remkoweijnen.nl/blog/2009/06/23/patch-vistas-kernel-to-address-more-than-4-gb-of-… 11/17 18.01.2020 Patch Vista's Kernel to Address more than 4 GB of Memory | Remko Weijnen's Blog (Remko's Blog)
https://www.remkoweijnen.nl/blog/2009/06/23/patch-vistas-kernel-to-address-more-than-4-gb-of-memory/In the Version tab, look for the original file name property. For Go JUN AUG MAR ⍰ example, on my PC it’s halmacpi.dll. So, you need to extract ❎ 10 captures halmacpi.dll from XP SP1 distributive to system32 folder, and 27 f 2 Jan 2015 - 26 Apr 2019modify/add the boot.ini menu to include it like this 2015 2017 2019 ▾ About this capture
multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Windows XP Professional patched halsp1″ /pae /fastdetect /kernel=ntkrnlp2.exe /hal=halmacpi.dll
Not sure which hal.dll you’re using, but it works ok on my pc, usb drives and DMA are working.
Do not try Server 2003 SP2 halls, as they are not binary-compatible with XP (different set of imported/exported functions)
ouay 68 April 27th, 2011 at 20:26
Uh. Shame. I just replaced hal.dll with this one from SP1. Will test proper way now! Have you USB issues with original SP3 hal? Or it is just me?
“[…] but it works ok on my pc, usb drives and DMA are working.”
So? You think such tweaked XP (patched NTKRNLPA.EXE + halmacpi.dll from SP1) is OK for smooth using 4GB+? Or there are/will be other (yet hidden) problems?
It is great challenge to do it. Even it is not needed prolly.

Well, on my pc, usb camera is not working correctly (seems that palette/camera data is completely wrong), but this may be the problem of the poorly written driver. Sometimes I’m also facing the bugcheck (blue screen) if I try to shadow the console session from the RDP session. Apart that, everything seems to work ok. I would recommend you to do a very proper testing of the system before using it in your home/dev environment.

You’re free to write it yourself Actually i do not think that using SP1 hal.dll on SP3 machine is a good idea – that’s why i never published it. The proper way is to patch hal.dll from SP3, but, as it cannot be simply patched (the function code was simply removed, so it requies something like full decompilation – change implementation – full recompilation), i cannot offer this solution.

I am trying to patch Windows Home Server 2011 to allow more than 8 GB, as i have 16 GB installed and want to use those for VMs as well.
I have put the Kernel into IDA and I can Find ZwQueryLicenseValue/ExVerifySuite, but the references are quite different different on this (x64) kernel. There are no such xmls and it seems different in the registry too. The Kernel seems to do it in a different way. Also the function MxMemoryLicense does not exist…
Anybody has a clue how to get the Kernel to allow all the memory ? I have studied Geoff’s article as well but it is a dead lead for x64 as well it seems …

Hello [email protected], “Remap memory”, “memory swap”, or “swap memory above 4G” bios setting must be also activated. If the memory is not swapped, nothing will give you your memory, since these addresses (between 3 and 4 GB) are usially used to connect to hardware.
magicT00n 79 August 20th, 2011 at 12:44
It is worth to note, that some older Mainboard chipsets, just can not do this, they are limited to 3+ GB by Hardware, like certain intel chipset (mobile 845 and others i believe, i have this issue on Sony Napa based Notebooks for instance). Nothing you will go will give you more ram on those, even you run x64 will not give you the full ram inserted.

daNIL 85 September 10th, 2011 at 20:05
Hello TomyLee,
You shouldn’t always take the HALMACPI.DLL, you should follow my procedure and identify the correct hal.dll for your particular system before patching. Using incorrect hal.dll can prevent your system from booting in this configuration.
And again, if you doubt about this procedure (windows xp patching), just create a bootable windows xp x64 or any 64 bit operating system partition/usb/cd drive, and try to boot it. If it shows you all of your memory, then something is wrong with the patching.
If it still cannot use all of your memory, then there is nothing you can do, as it’s a hardware problem.

Mauro, tested your patch. Few comments:
– it’s better to use %windir% variable, cause not everyone uses c:\windows. – it’s better to add a string to boot.ini, then overwriting it completely. – it’s better to patch user’s ntkrnlpa.exe, then using one from patcher’s machine. F.e. I had the same version (5.1.2600.6055) but somehow it had a different size and yours didn’t work for me, I had to patch my file manually.
And finally, this VSuite RAMdisk didn’t help to solve USB unavailability for me out of the box. Trying now to fix it somehow…
gespenst 91 December 24th, 2011 at 14:57
And Mauro, why do you put halmacpi.dll in your distribution? Is it kinda special? I’ve read that some people put halmacpi.dll from XP SP1, but yours is from XP SP3 according to file version (5.1.2600.5687 (xpsp_sp3_qfe.080930-1426)).
