  1. Master Chief's P5K PRO ACPI Warfare

    Hi farski, I have my audio working and I can't see why yours should not work. We have the same P5KPro. I modified my DSDT to have all the wonderful changes in Master Chief's DSDT (i think he will start wearing his underpants outside his trousers soon ). I did a LOT of searching on these forums. Look for anything on ALC883 and you will finds quite a bit of information. The steps I did were: 1) patch my DSDT to get Audio device recognised by System Profiler. 2) Use LegacyAppleHDAHardwareConfigDriver.kext and LegacyHDAPlatformDriver.kext. 3) Patch the LegacyAppleHDAHardwareConfigDriver.kext for the right verbs for P5KPro. See Verbs dump in linux Also http://www.insanelymac.com/forum/index.php?showtopic=171183 http://www.insanelymac.com/forum/index.php?showtopic=143697 http://www.insanelymac.com/forum/index.php...149128&st=0 I get a few sound assertion errors at start which other people have reported as well but the sound works. I've attached my DSDT (with master chief v2.4 mods) and my patched kext for you to try. Also make sure your bios is latest as well as Master Chief said. My processor is Core 2 Duo E6750 2.6gz in the DSDT. Jag P5KPro_1303.zip
  2. Hi, I just got my Speedstep to work using AppleIntelCPUPowerManagement thanks to the posting by Master Chief DSDT for P5K PRO. I was stuck and going out of my mind to make it work. It was working with PM Disabler kext. It turns out I was missing the very basics. Asus P5K Pro motherboard doesn't have a SSDT table to dump and I kept getting very confused about how to convert the ubuntu dumped SSDT lines (....CPU1PM..., ....CPU2PM...) from dmesg into DSDT method ubuntu acpi dump. The penny dropped when I looked at Master Chief's DSDT file and realised that I just needed these two in the structure and nothing else. I kept seeing other posting with all sorts of tags like CPU1IST, CPU0CST and wondering what to do in my case. Secondly I needed p state values for my processor E6750. Using the calculator in the first post, and the p states showing in CPU-I, I got the following (not sure if they are 100% correct but they work with very limited testing) Name (_PSS, Package (0x03) { Package (0x06) { 0x00000A68, 0x000157C0, 0x0000000A, 0x0000000A, 0x0000082A, 0x0000082A }, Package (0x06) { 2331, 46352, 10, 10, 0x71A, 0x71A }, // 7 Package (0x06) { 1998, 37600, 10, 10, 0x616, 0x616 }, // 6 }) Thirdly, I was totally lost on the _CST method. Finally I needed to make sure my model was correctly set as MacPro3,1 in smbios.plist, DropSSDT=Yes in Boot.plist. Then it worked..... Anyway, thanks to Master Chief's posting I was able to use the information from his DSDT file to get my working. I'm attaching mine just incase it proves useful to someone. It was dumped using ubuntu, errors fixed and then fixed for ALC883, Nvidia 8600 GT 512mb, Time machine fix for Marvell Yukon 88E8056 and other fixes. I'm using BIOS 1303. I haven't fully tested but it seems to be working apart from oKitWaitQuiet timeout waiting to write kernel symbols error. But I'm not going to bother to try to fix this as I'll be trying Snow Leopard as soon as the DVD arrives in the post. A big thankyou to Master Chief update New dsl file uploaded. The old one had control characters in it. This one also includes a sata change to make it appear as ESB2 as well. Jag AsusP5KPro.zip
