Hi,
I got DH55TC (Bios #48) which is similar to DH55HC - Core i3 530 SMBios- iMac 11,1 running mountain lion 10.8.0,
I am able to generate PStates using the following processor scope,
Scope (_PR)
{
Processor (CPU1, 0x01, 0x00000410, 0x06)
{
}
Processor (CPU2, 0x02, 0x00000410, 0x06)
{
}
Processor (CPU3, 0x03, 0x00000410, 0x06)
{
}
Processor (CPU4, 0x04, 0x00000410, 0x06)
{
}
Processor (CPU5, 0x05, 0x00000410, 0x06)
{
}
Processor (CPU6, 0x06, 0x00000410, 0x06)
{
}
Processor (CPU7, 0x07, 0x00000410, 0x06)
{
}
Processor (CPU8, 0x08, 0x00000410, 0x06)
{
}
}
I get PStates Generated but end with a Kernel Panic as shown in the picture. I cannot downgrade to BIOS #28 as my processor is not supported in that version.
Have you achieved native speed stepping ? Please share your DSDT.
