Subject: Nforce2 66MHz IDE without idebus=xx and "Athlon-xp powersaving system lock"
Date: Fri, 16 Jan 2004 13:52:25 +0000 [thread overview]
Message-ID: <200401161352.25732.murilo_pontes@yahoo.com.br> (raw)
If all Nvidia Nforce2 based systems have 2 pci buses (First is 66mhz for onboard devices and
second is 33mhz for pci expansion slots) and IDE controller work in 66mhz,
will be change kernel to start IDE controller in 66mhz mode automatic?
Athlon-xp powersaving lock-up: mm series disable 'Halt Disconnect and Stop Grant Disconnect' on boot!
Without mm patchs I disable it with "athcool" tool, kernel developers maybe include
automatic disable 'Halt Disconnect and Stop Grant Disconnect' on Linus tree?

=====================================
!!!WARNING!!!
Depending on your motherboard and/or hardware components,
enabling Athlon powersaving mode sometimes causes that
* noisy or distorted sound playback
* a slowdown in harddisk performance
* system locks or instability
