Fix para CMOS reset após sleep

1 post in this topic

Recommended Posts

A maioria das placas mãe têm esse problema no Lion, se o sistema entra em repouso e volta (sleep/wake), após reiniciar ou desligar/religar o PC, aparece uma mensagem no POST sobre "CMOS reset". Em alguns casos a mensagem é sobre a configuração do CPU e não chega a perder as configurações do BIOS, mas ela sempre aparece.

 

Para evitar o problema podemos fazer uma pequena modificação na kext AppleRTC.

 

Faça backup da kext original

sudo cp -R /System/Library/Extensions/AppleRTC.kext /System/Library/Extensions/AppleRTC.kext.orig

Rode este comando para modificar a kext

sudo perl -pi -e 's|\x8b\x45\xc8\x39\x45\xcc\x74\x0b|\x8b\x45\xc8\x39\x45\xcc\xeb\x0b|; s|\x8b\x45\xb4\x39\x45\xb8\x74\x08|\x8b\x45\xb4\x39\x45\xb8\xeb\x08|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC

Em seguida atualize o kernelcache (ou o Extensions.mkext, se você usar)

sudo touch /System/Library/Extensions

 

Agradecimentos a tseug/blackosx/DHP e outros pelo patch.
