**Definitive CMOS Reset fix**


56 posts in this topic

Recommended Posts

I think the cause of the CMOS reset in my case is NOT related to the RTC. I have absolutely no problems so far except for a BIOS beep on every boot/restart.

 

You can't fix it this way so, probably isn't related to RTC. But maybe it's a similar problem.. something addressing memory in the wrong place or with wrong size/lenght. And probably can be fixed via dsdt.

I think it's the fact that there is already enough information about editing the DSDT and most people more or less should know how to add an entry. I don't think it's really necessary to get redundant and keep posting the same info over and over and over and over.... :wacko:

Um, afraid of something...no. This seemed to be the only place to post about it since Snow isn't officially released yet. This area of the forum has the most posts related to Snow osx86 or mac.

i've try this tweak but no success with my Acer lap with Phoenix Technologies Bios

 

i compare my section for RTC with original MacBookPro3.1 RTC and they look the same

 

Device (RTC)

{

Name (_HID, EisaId ("PNP0B00"))

Name (_CRS, ResourceTemplate ()

{

IO (Decode16,

0x0070, // Range Minimum

0x0070, // Range Maximum

0x01, // Alignment

0x08, // Length

)

})

}

 

and if i'll leave it like it is with 0x08 or change this to 0x02 Bios got still reset. any suggestions ?

try this - replace entire block

 

 

Device (RTC)

{

Name (_HID, EisaId ("PNP0B00"))

Name (_CRS, ResourceTemplate ()

{

IO (Decode16,

0x0070, // Range Minimum

0x0070, // Range Maximum

0x01, // Alignment

0x02, // Length

)

IO (Decode16,

0x0074, // Range Minimum

0x0074, // Range Maximum

0x01, // Alignment

0x04, // Length

)

})

}

Hi

I have resource template ATT0 and ATT1 do I need to set both lenght values to 0x02?

 

Device (RTC)

{

Name (_HID, EisaId ("PNP0B00"))

Name (ATT0, ResourceTemplate ()

{

IO (Decode16,

0x0070, // Range Minimum

0x0070, // Range Maximum

0x00, // Alignment

0x04, // Length

)

})

Name (ATT1, ResourceTemplate ()

{

IO (Decode16,

0x0070, // Range Minimum

0x0070, // Range Maximum

0x00, // Alignment

0x04, // Length

)

})

 

Thanks in advance

0x04, // Length

)

})

}

 

 

so should i use both entries for Length 0x02 and 0x04 together like it is ? and Range Minimum and Range Maximum with both values 0x0070 and 0x0074 ? why's that ? help me understand

As far as i can test in my machine, only ATT0 is used. My RTC has some more values than yours (check my first post on first page) ... ATT1 seems to be for some situation that i can't understand.

Back to more testing...

}

 

 

this solution also not working for me ... i think that Phoenix Technologies Bios can't be solved this way ..maybe some other suggestions ?

You guys could just use the RTC code from my first post. I think it'll replace that stuff just fine. :)

i've tried but won't work with this code also. so i think that Phoenix Bios can't be solved this way.
