in dsdtse application the fix of cpus=1 is writen in the following way
Quote:
CPU ALIAS FIX.

This is maybe the easiest fix of all DSDT fixes, simply use the code browser using the CPU option and remove all the lines that say "alias"

Example:

BEFORE:

Scope (_PR)
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
Processor (P002, 0x02, 0x00000000, 0x00) {}
Alias (P002, CPU2)
Processor (P003, 0x03, 0x00000000, 0x00) {}
Processor (P004, 0x04, 0x00000000, 0x00) {}
Alias (P004, CPU4)
Processor (P005, 0x05, 0x00000000, 0x00) {}
Processor (P006, 0x06, 0x00000000, 0x00) {}
Alias (P006, CPU6)
Processor (P007, 0x07, 0x00000000, 0x00) {}
Processor (P008, 0x08, 0x00000000, 0x00) {}
Alias (P008, CPU8)
}


After:

Scope (_PR)
{
Processor (P001, 0x01, 0x00000810, 0x06) {}
Processor (P002, 0x02, 0x00000000, 0x00) {}
Processor (P003, 0x03, 0x00000000, 0x00) {}
Processor (P004, 0x04, 0x00000000, 0x00) {}
Processor (P005, 0x05, 0x00000000, 0x00) {}
Processor (P006, 0x06, 0x00000000, 0x00) {}
Processor (P007, 0x07, 0x00000000, 0x00) {}
Processor (P008, 0x08, 0x00000000, 0x00) {}
}
but in my case cpu menue in dsdt file is writen in the following way
Scope (_PR)
{
Processor (CPU0, 0x01, 0x00000410, 0x06) {}
Processor (CPU1, 0x02, 0x00000410, 0x06) {}
Processor (CPU2, 0x03, 0x00000410, 0x06) {}
Processor (CPU3, 0x04, 0x00000410, 0x06) {}
}

Do you have "Execute Disable Function" in your bios if so put it to enabled

Not really got any other ideas, I would try playing around, maybe try something like below.
I noticed that your cpu started numbering from 1 where all others I have seen start at 0, don't know if this will make a difference or not.

Scope (_PR)
{
Processor (CPU0, 0x00, 0x00000410, 0x06) {}
Processor (CPU1, 0x01, 0x00000410, 0x06) {}

}


If you leave your original dsdt in place and call the new one something like TestDSDT.aml
you can specify DSDT=TestDSDT.aml at boot

Therefore you can play around until you find something that works.
Hope this helps

What happens exactly when you just try to boot without giving CPUS= ?

If its your mouse jumping around, sudden lags, etc, try VoodooTSCSync. Some bioses (mine) don't give OSX the information it needs to synchronize the cores.
