Wake From Hibernate Fails Incorrect Signature Header

[4everAnoob]

I have everything working on asrock 4core1333 glan m box except sleep mode. Sleepenabler didnt help so with pmset i enabled Hibernate. Now it hibernates fine but wont wake instead bootloader just skips the sleepimage with said error (incorrect signature 200 or something)

 

Another (off topic) issue is that i installed using myhack 3.1 and chameleon has no gui. Even if i install chimera or another chameleon it still stays in text mode.

 

Any ideas are welcome

careful with pmset, better for viewing current config than changing, not to mention for a desktop you want 0 not 3 or 25 which is what I think you changed it to. Sleepenabler is not compatible with lion afaik, and is buggy at best under snow. You need to hav your bios set to suspend mode s3 and probably turn off "repost vbios on wake" or whatever similar setting it may have. DSDT edit may be needed as well, but try all that first. Then patch appleRTC.kext using Rayap's perl script

sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' /Extra/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC

script is written with expectation appleRTC.kext is in your /Extra folder, just copy it there, run script and install back to S/L/E. Verify smbion in /Extra is for an appropriate mac model and not a laptop. Also can change the system type in org.chameleon.Boot.plist

 

<key>SystemType</key>
<string>1</string>

with 1 being desktop, 2 laptop and 3 workstation

 

for GUI, check org.chameleon.boot.plist in /Extra folder and look for either;

<key>Quiet Boot</key>
<string>Yes</string>

and delete entry. Or

<key>Theme</key>
<string>Default</string>

and add it if you don' have it.

also look for timeout and in the string you can change the number of seconds the GUI shows before booting default partition. If your looking for the spinning wheel with grey apple logo while booting vs. verbose boot, stay with verbose, grey apple is not very exciting and verbose is far more useful, especially on a new install.

Thanks for your fast response! The bios settings are all correct. I thought that script was to prevent CMOS resets, does it do anything else? About DSDT, I couldn't find any DSDT for my motherboard and I have no idea how to make on myself :S

It shouldn't do anything else, but have heard people say it fixed other sleep issues, maybe just placebo effect tho. But if your cmos resets every time you sleep, not sure you'll be sleeping much unless you like going into the bios to reconfigure all settings before every boot.
