Asus P8Z77-V LX bios 1404 working sleep DSDT

2 posts in this topic

Recommended Posts

finally got the sleep working.. so much comparing this P8Z77-V LX board to to P8Z77-V Pro dsdt to get sleep and it never hit me.. i had forgot to patch AppleRTC.kext binnary

i turned off Com1 in bios
also the CSM Compat. enabled and chose LegacyOPRom so it doesnt try to boot EFI for win8.

also need to enable CStates in bios. (would love to give exacts screens but i didnt take pics when i built it for a friend)

8GB ram in 2 slots. ( u can choose whatever u want and reconfigure dsdt  mem from your dumped dsdt )
ATI 6870 XFX brand 1GB device-id 6738... in dsdt is faked as device id 6720 (radeon 6970) that is in iMac 12,2

(use imac 12,2 smbios with chameleon wizard)

u can use whatever video card that is compatible if u remove this 6870 ati from dsdt

Method (_DSM, 4, NotSerialized)
Store (Package ()

0x20, 0x67, 0x00, 0x00
Buffer (0x0D)

"AMD Radeon HD 6870"
Buffer (0x0A)
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)

create SSDT with Revogirl's (if u get inet in heaven..ty and rip wizgirl) ssdtPRGen.sh for your cpu if u get error 18 speedstep something something.. also dont forget to DropSSDT in chameleon wizard  -_- 

no RTC0 0x02 needed in DSDT. sleep works fine with 0x08.
but it does need AppleRTC.kext RTC sleep reset patched if 10.7 or 10.8

EDIT: Link is for DSDT.DSL not compiled.



use dsdt editor to compile then save as /Extra/DSDT.aml

(why this way ?  so u actually check your GNVS to match by ram ammount)
check your dsdt for this to match.. changes with ram amount.  ( search dsdt for GNVS )

OperationRegion (GNVS, SystemMemory, 0xDE251E18, 0x01D1)
if it is different.. update my dsdt with your GNVS line and enjoy.

i have flashed mod bios 1404 in USB DOS
(in windows make a DOS USB Bootable)
then use these files in usb to flash bios http://www.mediafire...ulh38vropdnu43i
with flashrom in dos with this commands. (rename the bios long name to mod.rom)


i made a backup first (bkup.bat) with:

flashrom -p internal:laptop=this_is_not_a_laptop -r backup.rom


then i flashed with 
Mod.bat that runs the code below
flashrom -p internal:laptop=this_is_not_a_laptop -w mod.rom

biosmod done by samisnake.. THANKS!

the reason for DOS is DPCI tool wants mountain lion .. not lion.

hirensbootcd.org anyone ?


CodeRush advices not to use flashrom but instead FTK for flashing stability issues like this



how its done
