    OK. Keep us informed

    Bummer... Good luck forcing BIOS image. I never got it to work in Chameleon. Make a stop here first, for some already dumped BIOS ROM images...

    Hello again. I think I can be of help. As I've mentioned I've dealt with that problem before. And I have solved it! It's interesting that you have done your homework. Those steps you took are indeed supposed to help. And yet they didn't So what's wrong? As you probably already know, your problem is framebuffer related. It looks like your system uses the default Radeonframebuffer instead of the native one for the 5450, even though chameleon bootloader tries to inject the correct values, through Graphicsenabler=yes. It simply won't do the trick. And you DO need the appropriate FB to load as it gets involved not only in DVD Player.app function but in proper graphics output (esp. in games/animation software). Fortunately there is an alternative. The kext I have attached (ATY_init.kext) is written by netkas and it is supposed to inject some missing values concerning your display adapter. Copy this kext to /S/L/E (not /E/E, it won't work!) and turn off Graphicsenabler. Update kext cache with Kext Wizard and reboot. Once again run ioreg and paste results. When i "ioreg|grep ATY" my ATI Radeon HD 4890 OC i get this: AMD-OSX86:~ user$ ioreg|grep ATY | | | | +-o ATY,MotMot@0 <class AtiFbStub, id 0x1000002de, registered,$ | | | | | +-o ATY_MotMot <class ATIFramebuffer, id 0x1000002e0, regist$ | | | | +-o ATY,MotMot@1 <class AtiFbStub, id 0x1000002df, registered,$ | | | | | +-o ATY_MotMot <class ATIFramebuffer, id 0x1000002fb, regist$ AMD-OSX86:~ user$ MotMot is the framebuffer I need. Previously I had RadeonFramebuffer. ATY_Init.kext.zip

    Can you be more specific? Exactly which symptom do you get? Does DVD Player.app crash every time you open it? I had a similar case with another osx86 system, running 10.6.8. The DVD-ROM drive should not really matter, do you have the GSA-H31N? My 745 plays DVD Video with Apple DVD Player just fine. Please open Terminal.app, type the following line: ioreg|grep ATY hit ENTER and paste the output here.

    It'd be nice if we could get the following: Native CPU PM Proper S3 sleep/resume, without the need of any kext (I use sleepenabler.kext) Proper shutdown/reboot, without delay, again without the need of any kext (I use EvoReboot.kext) USBEHCI full compatibility (for now USB 2.0 devices get disconnected right after S3 resume, system displays a warning message) Regarding low mic level, have you bumped up "Mic", "Input Gain" and "Recording level" sliders, all three of them? Which VoodooHDA kext did you use?
  6. OS X 10.7 (Lion) install on Dell Optiplex 745

    @BugsB and everyone concerned The DSDT.aml file I tried unfortunately does NOT seem to cure problems present in a 745 OS X system. Computer takes a bit longer to enter sleep and much longer than normal to wake from S3. Sometimes it won't resume on the 1st attempt, you need to press a key or mouse button for a 2nd time. In addition USB 2.0 devices disconnect with a system warning message right after a S3 sleep/resume. Also I am not sure if speedstep works, even though it is enabled in BIOS (have you included a relevant patch/fix in the DSDT BugsB?) System functions just the same without the DSDT.aml file (I think we need help by Mald0n at this point). I use Sleepenabler.kext in /E/E, computer sleeps and wakes up instantaneously, only sometimes display takes a couple of seconds to come back. Imac9,1 system definition seems to work better Try inserting these lines in your smbios.plist <key>SMproductname</key> <string>iMac9,1</string> This way you will not need NullCPUPowerManagement.kext (but you DO need it if you use Imac8,1, without it CPU performance drops significantly) As for RAM speed being reported wrong do not worry. It's only of cosmetic importance, memory modules still run at 800 MHz. (I also get the speed shown as 531 MHz) If you badly want to change that, you can put those lines in your smbios.plist <key>SMmemtype</key> <string>19</string> <key>SMmemspeed</key> <string>800</string>

    Thanks for providing us with the DSDT file. I'll try it and post back my experience. From time to time I update/correct the wiki. I'll take into account your suggestion regarding support info for the onboard GMA3000. Take care
  8. OS X 10.7 (Lion) install on Dell Optiplex 745

    Okay. I think I know what's happening, I had that problem on my initial setup. No DSDT is needed. Just like you guessed you have to apply the patch (provided by rayap) to the original AppleRTC.kext in /S/L/E. Just run terminal and paste this line: sudo perl -pi -e 's|\x75\x30\x44\x89\xf8|\xeb\x30\x44\x89\xf8|; s|\x75\x3d\x8b\x75\x08|\xeb\x3d\x8b\x75\x08|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC Press enter, type in your PW and once again hit enter. This is the AppleRTC patch that will prevent your 10.7 system from getting a partial BIOS reset after an S3 sleep/resume cycle. This will cure your internal NIC disappearing (reverting to "Off" in BIOS) and your PC auto turning on at 12.00 A.M. (BIOS feature). I thought you would not have missed that, it was mentioned in the notes section of the osx86 wiki. :-) Good luck... P.S. rayap revised the script, take a look at his later post I have no idea. Some other user edited my osx86 entry for the 745, he mentions sth about the GMA3000 being supported. You could email him I suppose.
  9. OS X 10.7 (Lion) install on Dell Optiplex 745

    @BugsB, carrick I don't have the NIC wakeup problem on the 745 (and I use no DSDT). Can you describe the issue in detail? Did you follow this guide step by step?
  10. Hello. Thx for those kexts, they really did make a difference. I have a problem though, maybe you 've already come accross such a case. System is AMD osx86, v. 10.6.8 I'm using your 10.8.0 R2 legacy kernel and nawcom's Sleepenabler.kext. All is working F-I-N-E with the proper bootflags and kexts, except for one thing. When I first tried the sleep function the system entered S3 mode withouth a hitch. But waking up yielded the following result. All USB ports were dead/powerless (No KB/mouse, replugging did not help so I had to restart to gain back USB functionality). Cue some vigorous googling, I learned that my problem was related to the USB controller(s) being seen by OS X as "Expansion slots". Then I came across this thread and did some testing. Indeed the patched version of IOUSBfamily (v 4.2.4) which you uploaded did the trick and now controllers are seen as "Built in". This fixed the broken USB function after S3 resume but apparently only for the OHCI controllers. That is to say, any USB 1.1 device connected prior to S3 sleep will be online right after wakeup but the same doesn't hold true for USB 2.0 devices, such as pendrives, HDD's and webcams. If a USB 2.0 device is hooked on any port after system wake from S3, then the device will not come back. Moreover the EHCI controller will appear (frozen) in System Profiler as though it still has the device connected when in fact it is already powered off (inserting any new device in any port will result in absolutely no USB connection). Also when this scenario takes place system will hang amid a restart/shutdown sequence. A hard reset is required. Following are the USB controllers as listed by lspci -nn 00:12.0 USB Controller [0c03]: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller [1002:4397] 00:12.1 USB Controller [0c03]: ATI Technologies Inc SB700 USB OHCI1 Controller [1002:4398] 00:12.2 USB Controller [0c03]: ATI Technologies Inc SB700/SB800 USB EHCI Controller [1002:4396] 00:13.0 USB Controller [0c03]: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller [1002:4397] 00:13.1 USB Controller [0c03]: ATI Technologies Inc SB700 USB OHCI1 Controller [1002:4398] 00:13.2 USB Controller [0c03]: ATI Technologies Inc SB700/SB800 USB EHCI Controller [1002:4396] 00:14.5 USB Controller [0c03]: ATI Technologies Inc SB700/SB800 USB OHCI2 Controller [1002:4399] Mainboard is ASUS M4A78T-E. I've tried each and every possible solution I read to no success. Most people talk about DSDT patching which unfortunately doesn't seem quite straightforward when it comes to the AMD platform... Anyone got any clue as to what may be causing this glitch? T.I.A., have fun h@ckint0shing
  11. Successful Retail Snow Leopard AMD

    Hello. Have you made any progress on the sleep/resume issue?
  12. I' ve had a 8400GS 256MB video adapter recognized in OS X 10.7 with full QE/CI support just using the "GraphicsEnabler=Yes" option in /Extra/org.chameleon.Boot.plist file. This switch practically orders the injection of the EFI strings present in your video card. com.apple.Boot.plist is considered obsolete by newer versions of Chameleon/Chimera bootloaders and thus it is not used/read.

    Need more info to help. Please boot in verbose mode using -v switch (type -v at the command prompt and then press ENTER) ...or simply give it some more time, here's something I came across: "It may pause on the grey apple screen with the spinning wheel for quite some time. Just let it be."

    Hi. We mostly refer to DFF, as it happens to be the most upgrade friendly (regarding RAM, expansion cards etc) form factor of the Optiplex 745. Thx for your comment. :-)
  15. OS X 10.7 (Lion) install on Dell Optiplex 745

    Hello again. As it's already been mentioned the GMA3100 won't work, so you can forget about it. As for sound, take a look again at the wiki. You need the patched VoodooHDA kext I have uploaded. It's for ICH8 HD audio which I believe your 745 has (it's not AD1983). Finally there is a solution for the Mac App Store login problem. Read the relative comment in the wiki. If you do not understand take a look at this post
