DSDT patch request: ASRock H77M-ITX

[BoomR]

I flashed my new board to the latest BIOS ROM - 1.10, then did successful unishit (v1.3) install of 10.7.4. No problems thus far, except I didn't have any Ethernet support once I got to the desktop. No biggie - had DSDT Editor on a USB flash drive as well as Java Runtime installer.

Ran DSDT Editor & extracted DSDT, then I followed the instructions in DSDT 101 posting and applied all the usual/customary patches plus my specific audio patch. When I went to compile, then fix errors, I still get this one lingering error:

When I click the error message to see the detail, here's what is displayed:

It appears that, until I correct this error, I cannot get to the "Save as AML..." command (grayed out).

I'm attaching the original DSDT that I saved before all my mucking about. Any assistance with creating a proper patch which I can then apply would be much appreciated!

I don't know the correct fix for this error.

If you just remove the non-hex digits you'll be able to compile, but I don't know if it will have any side effect.

Replace "ABCDEFGH" by "ABCDEFFF" (instead of FF it could be any digit 0-9, A-F).

UGH... trying this again:

Based on re-reading DSDT 101 a bit more thoroughly, I've applied the following patches:

Power Management:

LPC Sandy Bridge

HPET

USB:

EHCI

ICH9 USB sleep

Others from DSDT 101:

RTC

ACL892

DTGP

IRQs

SMBUS

IF I try to apply HDEF, I get a bazillion more errors

...but if I omit applying HDEF, then compile & "fix errors," and fix the hex error per your suggestion, I'm down to 1 error: "Object does not exist (ATT3)" - see attached screen grab.

I'm attaching a "fresh" extract of the baseline DSDT (I re-flashed the bios, then used DSDT Editor to extract after initial 10.7.3 unishit install), as well as the patched version with the 1 remaining error. I welcome any insights or suggestions. THANKS!

adapt _CRS to return the ResourceTemplate right above

You need to replace ATT3 by BUF0

                    Method (_CRS, 0, NotSerialized)
                   {
                       Return (BUF0)
                   }

 

You don't need HDEF patch, the device already exists.

Thanks very much!! I'll try that first thing in the a.m.

I'm really excited to get this build working - I'm doing a G4 Cube hack . Unlike the gigabyte mini-ITX board, this one has a few extra mm's between the edge of the circuit board & the outside DIMM slot, leaving room for me to still use the original touch-sensor power button!!

[BoomR]

Made the edit, compiled - no errors! WOOT! Home free!

...or so I thought.

Alas, my old friend kernel panic paid me a visit just now...

Also attaching a copy of the DSDT file with the last round of edits. Any additional thoughts as to what I may need to add/remove?

Did you patch AICPM? http://Olarila.com/forum/viewtopic.php?f=9&t=1003

You are using wrong SMBIOS, should be iMac12,x http://Olarila.com/forum/viewtopic.php?f=2&t=1302

ERP... I didn't even think to select a profile like Mini or iMac at this state... and no, I didn't do the patch. Crap. Just to confirm: I extract the .zip file on my Hack once I've completed my initial lion install - and run it as instructed either before or after I run multishit & use my DSDT (but before I reboot after running MB)?

This is definitely a steeper learning curve than I thought. I appreciate your patience and assistance!!

[Cassio]

You can patch AICPM at any time. You need to do it again after updates. During update, use NullCPUPowerManagement.

[BoomR]

In Lion Edition multishit, there's now an option in the Kexts/Enablers section for the AICPM - see attached. Selecting the option for 10.7.3 (which is what I'm using) as well as the iMac 12,2 option via MB should give me the equivalent of what you were suggesting via the patcher + the Chameleon Wizard screen grab you included, correct?

[Cassio]

I have no idea, I don't use/support this tool.

[BoomR]

Understood. I'm assuming that you're more familiar (and support) the OSx86/InsanelyMac form/tools? I may need to start doing some additional studying & get up to speed on that process & tools.
