Snow Leopard CMOS reset fix
Snow leopard beta's have the nasty property that when you reboot it resets your cmos. You can fix this by editing your dsdt file.
Length should be changed to 0x02, its normally 0x04. Code:
Device (RTC) { Name (_HID, EisaId ("PNP0B00")) Name (_CRS, ResourceTemplate () { IO (Decode16, 0x0070, // Range Minimum 0x0070, // Range Maximum 0x00, // Alignment 0x02, // Length ) }) } |

candykane,
With Leopard 10.5.6, I have: Code:
Device (RTC) { Name (_HID, EisaId ("PNP0B00")) Name (_CRS, ResourceTemplate () { IO (Decode16, 0x0070, // Range Minimum 0x0070, // Range Maximum 0x01, // Alignment 0x08, // Length ) IRQNoFlags () {8} }) } a. the change you suggest is harmless on Leopard b. whether the IRQNoFlags needs to be there or not in Leopard/Snow Leopard? Thanks. -- MacBook Pro - have allergy to nickel in the aluminum casing. So my kid gets an expensive toy! Gateway MX 8738 - Retail, vanilla Snow Leopard 10.6.2 (thanks kizwan!) with Chameleon RC4, modified DSDT. Upgraded to Core 2 CPU (easy to do). Upgraded to 640GB drive. Everything but SD card working. Minor niggles. GMA950 with QE/CI and *no* artifacts. iMac (luxo/lamp) G4 with Tiger. |

uman,
Absolutely harmless on either OS. That 8 needs to be changed to 2, but has no affect in Leo. The IRQNoFlags and following line {8} needs to be deleted, too. Were you experiencing KPs in SL? I don't know about Leo, but this is known for KPs in SL on ASUS boards. regards, MAJ |

Thanks, I'll make the change.

download this app http://www.applelife.ru/poleznye_kek...tml#entry93244 after you drag your dsdt.aml you will get a dsdt.dsl which you can edit. once your done just drag your dsdt.dsl back to the app and it will transform it back to dsdt.aml just like magic |

On Device (RTC) section I have the value 0x04 for alignment. I saw on the first post that candykane has 0x00 but on the following posts nobody comment anything about that. Do I have to set the alignment value to 0x00 or leave it with its current value?
thanks in advance! Last edited by dgandra; 09-05-2009 at 02:18 AM. |
