I just installed Kalyway 10.5.2 on a GA-P35 Ds3L / Q6600 / 4gb RAM system; all's well except that the Q6600 is detected as a single core CPU. I had set up Kalyway on my other GA-P35 Ds3L just a couple weeks ago, pretty much identical machine yet it's Q6600 is showing correctly as 4 core. FWIW both are GO step Q6600's OC'd 2.91ghz. I don't recall the Options I chose for the setup, should I re-enter the setup via the kalyway disc and select options I may have overlooked, or can I fix this within the present install?

I didn't select any boot options at all, either on this latest GA-P35 Ds3L rig or when installing Kalyway on the first GA-P35 Ds3L machine. Both machines are identical in every way(mobo/RAM/vid etc) hardware-wise, and BIOS settings are all the same:
Limit CPUID=disabled
No-execute=disabled
C1E=disabled
TM2=disabled
EIST=disabled
ACPI=SI
PME=Enabled
HPET=32 bit


Used same Kalyway disc as well. I did try cpus=1 but there was no effect...

upgrade to 10.5.8 and try again.
makes no sense to fiddle with 10.5.2.
and first of all which kernels did you try?

btw light green on a white bg sux

Try this bios setting :

Limit CPUID Max. to 3: [Disabled]
No-Execute Memory Protect: [Enabled]
CPU Enhanced Halt (C1E): [Enabled]
CPU Thermal Monitor 2(TM2): [Enabled]
CPU EIST Function: [Enabled]

10.7 Lion Dev Prev

Good deal, thanks so much! Quite a few BIOS settings were not correct, after correcting those & and using the -v flage plus "cpus=4" the install is using all cores. I still have to use the 'CPUS=x" argument when rebooting my dual core E6300 rig; I haven't rebooted my quad yet to see if the cpu core seting 'stuck'.
Would using "-f" help, or do I need to Edit the Plist?

plist entry would do the job.

Update:
Having gotten thus far, I decided to re-try iAtkos v.7 rather than spend the time applying updates to 10.5.2. iAtkos worked beautifully with the correct BIOS settings, now have 10.5.7 on a couple C2D & CQD rigs. A big thanks to Apple, and to all the dev's plus those who posted with help.
