System Bus Extension from Romex installed and functioning correctly, but USB doesn’t work. Nor USB mice, nor storage USB Flash cards.

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)).

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…

the methd is same
boot.ini
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP Professional 8gb” /noexecute=optin /fastdetect /KERNEL=mykernel.exe /hal=halmacpi.dll /PAE

mykernel.exe is NTKRNLPA.EXE patched
using
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

c:\windows\system32\HALMACPI.DLL is last version 5.1.2600.5687

Mauro, isn’t it a trojan? Is there a more detailed information on that lone “exe”?

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.

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

(1000 is the Hex of 4096)
(4000 is the Hex of 16384)

2. Save the modified kernel as mykernel.exe and put it under C:\WINDOWS\SYSTEM32\

3. Look for C:\WINDOWS\SYSTEM32\HALMACPI.DLL(from WindowsXP SP1 x86)

4. Take the HALMACPI.DLL(from WindowsXP SP1 x86) and put it under C:\WINDOWS\SYSTEM32\

5. Open C:\BOOT.INI

Copy and paste your original boot option, but add the new parameter

example:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP SP3 X86 OVER 4GB RAM”
/fastdetect /NoExecute=OptOut /pae /kernel=mykernel.exe /hal=halmacpi.dll

6. Reboot, choose “Microsoft Windows XP SP3 OVER 4GB RAM” from the boot menu
