#1, this is not a valid report.
#2, to make this a valid report you must specify everything.
dev id Vendor id, sub id.
#3 what are you kernel arguments
#4 what are you org.chameleon.boot.plist flags
#5. where is your bdmesg post
#6. What version of chameleon.

Comment 2 by angel crane, Nov 28, 2012

i do not use any flags for boot up and i do not make it to the 
kernel boot up plus my plist is what ever was installed and the 
version is the lastest and explain what is bdmesg cause i have no 
clue.and vendor id or sub id how bought we pretend that i know what 
is but don't and you explain it to me cause this error happens on 
all let me say that again all 7970's

Comment 5 by Pablo C, Nov 29, 2012

Hello, I'm having the same issues, is this what you need?

PCI\VEN_1002&DEV_6798&SUBSYS_0B001002&REV_00
(This is for an AMD HD 7970)

Thank You!!!

Comment 6 by Cosmosis Jones, Nov 29, 2012

What is the bios size for those cards. It would appear memory is 
getting corrupted. i'd assume it's the size of the buffer is too 
small for teh bios.

what is the bios size? can you dump it w/ gpu-z in windows and 
attach?

thanks

@Paolo C

I add the Southen Island support in my brach long time ago.

Pls try and report this include your DevId+SubDevID
I set the FB to Bulrushes.

But as Ap*le will start support it from 10.8.3 I never been able to 
test it.

Also install the KernelPatcher.dylib module into /Extra/modules

Have fan

I've tried using your loader and I get a white screen after the 
Apple logo.
If I unplug and plug the display connector then, I can see the mouse 
(and it's small so the res is OK).

I might have done something wrong, what did you mean when you said 
that I had to include my DevID+SubDevID (I thought you wanted me to 
post it here but I'm not sure)

Thank you Fabio

Comment 10 by Pablo C, Nov 29, 2012

Fabio, if I use your bootloader from a USB drive I have the problem 
I mentioned above. 
If I install it into the HDD I have the same problem angel crane has 
(as if I use the last stable version), I get that random string of 
characters.

Comment 11 by sea man, Dec 2, 2012

Comment 20 by sea man, Dec 7, 2012

I tried today from a HD whit MBR partition scheme whit the 
Enoch-2137-i386.zip and it work !... seems like the guid partition 
scheme is the problem, because if i boot from guid disk partitioned 
always show the fancy characters.

Comment 21 by sea man, Dec 8, 2012

Tried today to boot from USB guid disk partitioned whit the 
Enoch-2137-i386 to discard a problem whit my ssd and again the fancy 
characters appear , anyone can confirm if is only my problem ?

Thanks !

Comment 22 by angel crane, Dec 9, 2012

we all have your issues the only time i boot without error is if i 
use champlist to update the bootloader to it's lastest

Comment 23 by sea man, Dec 9, 2012

Another issue:

If you change the theme.plist resolution ie: 1920*1080 you have :

Memory allocation Error (0xdeadbeef)

or

And a ati.c error in ramdom line...

or this :

Comment 24 by sea man, Dec 9, 2012

@angel crane 

The champlist did it !

Thanks !!

Now i can boot from my HD without a USB !!

Pd: forget my last report.. my mistake.. I'm booting whit GE=YES and 
also a DSDT whit my gpu injected.. because this i get this error.. 
after i put GE=No in my org.chameleon , it boot normally.

Comment 25 by Cosmosis Jones, Feb 1, 2013

I've added 7970's to the trunk.
On my own 7970 i can't get past the boot0: done

. 
Could you please test this in your own system?

Thanks
