Neo2 FR Q6600 only using single core

Question

After finally getting my system running I noticed that my new q6600 was not giving me anywhere near the performance I expected.  It's a little bit fater than my old p4 3.6Ghz POS.  Windows device manager does show 4 different CPUs, but task manager only has one graph and none of my audio programs allow me to turn on multiple CPU support (they should with a multicore processor.)  I also notice that the BIOS (1.2) does not show me the Hyper Threading Option.  Also, I have set;
(IO)APIC = Enabled
MPS Table Version = 1.4
there is NO APIC option in the bios, only (IO)APIC
Where have I gone wrong?
Running XP SP3
EDIT: CPU-Z only show 1 core, 1 thread

No, does not, it has "Advanced Configuration and Power Interface".  How would I enable ACPI Multiprocessor PC?  Will it require a re-install of XP?  I have now updated the BIOS to 1.6.
Right click on ""Advanced Configuration and Power Interface", and select update then pickup manually "ACPI Multiprocessor PC" from the List.
If its not listed or there is a troubles updating, you can try to force it via that way:
1. Changing HAL require changes in corespond kernels too. Each HAL use different kernels.
2. The HAL file along with corespond kernels need to match with exact XP version installed. Example:
If the user is using SP2(most popular and recent), we must use HAL & kernels version for SP2 too.(else will not gonna work)
So let's comment here again:
"expand d:\i386\halmacpi.dl_ c:\windows\system32"
If we use SP2, we need to use correct version of halmacpi.dll (in the string above its older version), we can get it from here:
expand d:\i386\sp2.cab -F:halmacpi.dll c:\windows\system32  /* I assume that we have XP SP2 installation disk */
or we can use other location, which will no need to have XP installation disk, XP is keep a copy of files locally, we can use this one instead too:
expand c:\windows\driver cache\i386\sp2.cab -F:halmacpi.dll c:\windows\system32
If we use SP3, we should use sp3 versions of halmacpi.dll,(and kernels which will be described below) e.g. in the string above we must replace sp2.cab with sp3.cab
OK, think that part should be clear, the next stage updating the kernels for our chosen HAL, ofc. we will follow the rule 1 they to match with our version used.
"ACPI Multiprocessor PC" is using those kernels: ntkrnlmp.exe, ntkrpamp.exe which must be renamed and overwritten to ===> ntoskrnl.exe, ntkrnlpa.exe in %systemroot%\system32 directory.
/* MS$ is using the same names for kernels, but in reality they are different for each HAL... */
So our complete scenario to successfully change(force "ACPI Multiprocessor PC") will look in that way:
expand c:\windows\driver cache\i386\sp2.cab -F:halmacpi.dll c:\windows\system32
expand c:\windows\driver cache\i386\sp2.cab -F:ntkrpamp.exe c:\windows\system32
expand c:\windows\driver cache\i386\sp2.cab -F:ntkrnlmp.exe c:\windows\system32
or better going to c:\windows\driver cache\i386\    folder 1st, to type lesser by:
cd c:\windows\driver cache\i386
and
expand sp2.cab -F:halmacpi.dll c:\windows\system32
expand sp2.cab -F:ntkrpamp.exe c:\windows\system32
expand sp2.cab -F:ntkrnlmp.exe c:\windows\system32
clearing the way for new HAL and kernels and making backup of current one in same time by:
ren ntkrnlpa.exe ntkrnlpa.old
ren ntoskrnl.exe ntoskrnl.old
ren hal.dll hal.old
then naming new HAL file with kernels to expected by OS with:
ren halmacpi.dll hal.dll
ren ntkrpamp.exe ntkrnlpa.exe
ren ntkrnlmp.exe ntoskrnl.exe
reboot PC by:
echo g=FFFF:0000|debug /* or just hit reset key...*/
In short to be more clear what we have changed:
To force "ACPI Multiprocessor PC", we need to overwrite:
extract & rename & replace(overwrite) Halmacpi.dll to ---> %systemroot%\system32\hal.dll
extract & rename & replace(overwrite) ntkrnlmp.exe to --> %systemroot%\system32\ntoskrnl.exe
extract & rename & replace(overwrite) ntkrpamp.exe  to --> %systemroot%\system32\ntkrnlpa.exe
Just we must be sure that source files will match with actual XP OS version, etc:
If we use SP2, we must get source files(Halmacpi.dll, ntkrnlmp.exe, ntkrpamp.exe) from %windir%\driver cache\i386\sp2.cab,
If we use SP3 we must get source files from %windir%\driver cache\i386\sp3.cab,
If we use SP1 we must %windir%\driver cache\i386\driver.cab
If we use XP without SP we must get the source files from %windir%\driver cache\i386\ /* they exist there but compressed, which can be done by same way with expand command)
Then just to rename files and replace into %systemroot%\system32 folder as followed:
Halmacpi.dll to ---> %systemroot%\system32\hal.dll
ntkrnlmp.exe to --> %systemroot%\system32\ntoskrnl.exe
ntkrpamp.exe  to --> %systemroot%\system32\ntkrnlpa.exe
We can use XP installation disk recovery console, we can use some DOS version which NTFS mounted which have write ability to NTFS, or just second OS installed to replace files from there.
Have used the procedure above xx times working every time without single issue
"Will it require a re-install of XP?"
As last resort yes.
