  1. 10.6.3 Released !

    You're seeing the difference between the delta and combo updates. In your case, OS X has detected that you only need the 10.6.2 - 10.6.3 update, not the complete 10.6 - 10.6.3. Sleepenabler will always panic if it isn't matched to the kernel version, so it would appear that 10.6.3 includes a new kernel. EDIT: yep. 10.3 kernel. There also doesn't appear to be a performance increase in OpenGL scores. At least, not on my Macbook. I'll have to test that out on the desktop hack tonight.
  2. Once that OS X bug bites, it becomes very tempting to see how well it works when it's running on the intended hardware platform. The complete integration makes the already strong OS X unbeatable, IMHO. I've only had the Macbook Pro a few days, but I'm already convinced that it's the computer for me. I just wish that Apple would ship a high-resolution display for the 13-inch models. After working with the Dell's excellent high-resolution screen, moving back to 1280x800 feels a bit constrained. I'm already getting used to it, but the extra pixels made a huge difference in productivty. I just wasn't willing to move up to the 15 for portability reasons.
  3. I'm no expert, but I'm glad that I was able to help out by collating the relevant info so that it was more easily accessible. You're right on that the only way forward from here is actually studying the ACPI specification and doing some honest-to-god coding. It's a tough slog, but there you are. For my own part, I'm not likely to be pursuing this DSDT stuff much further on the D620 because as of yesterday, my primary computer is a MacBook Pro. I'll still be running OS X on my desktop computer, but it's been nailed down in terms of DSDT patches since the override became available last year. I'll probably still follow this thread out of interest's sake. Best of luck to all of you and thanks to leppy for all the hard work!
  4. Well, I get between 3 and 4 hours on an extended battery with my D620. That's typically at half to 3/4 brightness and surfing the net/futzing in Terminal. On the Windows side, that battery is good for about 4-5 hours, so we are seeing a reduction due to inoperative C-States.
  5. Dual Core Timing Issue?

    Check it out: VoodooTSCSync That .kext should allow you to use both cores without issue. It works great on my Dell D620.
  6. USB isn't working? Oh. Not to be pedantic, but you're getting your terminology confused. 'Bootloader' refers to the program that passes the control of the system hardware over to the OS. In this case, the bootloader is Chameleon or a variant thereof. leppy has provided a boot CD with a Chameleon bootloader and customised drivers for the D620 notebook. The bootloader itself is hardware agnostic. What you need is a DSDT patch to properly recognize your USB devices. Check my other posts in this thread for guidance on patching the DSDT to get OS X to properly recognize USB. Are you getting any errors during verbose boot that have to do with 'Unable to intialize UIM' ? What would really help is if you could attach the results of lspci or an ioreg dump. LSPCI utils give a flat-file listing of all installed hardware and the pertinent vendor/device IDs. An ioreg dump can be obtained from Terminal (provided you installed the dev tools from the OS X install disc.) Either should point us towards a solution for both sound and USB.
  7. That error is normal. The problem is that the OS X install disc can't set the boot partition properly. If you reboot with the D620 boot disc and boot into your new install, you can then install the bootloader. DougHogue: You say that 'not much works,' but you then list everything that does work, and that list seems awfully long. You might try the old AppleAzaliaAudio patch that's floating around the boards. That fix worked for me on my old Toshiba A100. As for the wireless, like you said the 3945ABG isn't supported, but you can install any Broadcomm-based card and get full functionality. In any case, there is no such thing as a custom bootloader that is specific to a computer model. The booter that leppy uses was developed by someone who predominately supports Gigabyte-based desktop computers. So long as it's Intel-based, you're golden.
  8. All my function-keys work. I would avoid SleepEnabler like the plague. You don't need it anyhow.
  9. What program are you using to graph the temperature readings?
  10. Temperatures are in that range here as well. I think that when the Apple .kext is in control of the fans, they run much more conservatively than normal because Steve Jobs really, really hates noise. Once the fans kick in, temperatures drop into the mid to high 40's.
  11. I woudn't be futzing with two boot.plists if I were you. Leave the 'standard one' alone and just use the /Extra version. Feel free to post it here for us to look at. Are you running NullCPUPowerManagement or Disabler.kext? You need working vanilla power management for sleep to work. Asked and answered in this very thread. Check my posts on the previous page for the information you seek.
  12. Huh. Here's my untouched DSDT.dsl from an Ubuntu dump. My machine has 2x2GB of RAM, nVidia graphics, high-res screen and the fingerprint scanner. If you could do a diff bewteen this and yours, I'd be interested to see the results. I have the latest BIOS revision (A10). dsdt.dst.txt
  13. USB's dismount incorrectly due to the BIOS implementation. Dell has programmed the USB ports to cut power when not tethered to AC power. OS X doesn't know how to handle this and fails to unmount the USB drives properly. I tried adding the requisite flags in my DSDT to provide power to the USB ports while in sleep mode, but that only solved the issue while on AC power. When on battery alone, the USB ports do not provide power, period. As for speedstep, try setting your model to MacbookPro5,1 in the smbios.plist file. That worked for me to enable system-controlled speed-step, but c-states appear to be out of reach for now. As for RAM bandwidth, you're getting asymmetric dual-channel with your 2+1 GB configuration, which provides up to 95% of the bandwidth you get from true dual-channel. You'll see a drop in available bandwidth if you use only one DIMM.
  14. Just a caution about using other people's DSDT files: Sure, you may have the same hardware, but do you have the exact same RAM configuration as leppy? Does he have 2GB in one or two DIMMs? It makes a difference and using a DSDT generated by another computer with even the slightest difference in hardware configuration, BIOS revision or BIOS settings can result in kernel panics. My recommendation is to boot into a Ubuntu live environment, dump your own DSDT table and make the required patches from there. I know that it's not convenient, but it has the benefit of matching up exactly to your hardware and you might just learn something about the ACPI specs and how your computer behaves at the lowest level.
  15. I wouldn't bother myself with the 1.83GHz. My previous laptop was a Toshiba with a 1.6 GHz and I don't see too much improvement in 'day-to-day' usage with the D620 equipped with the 2GHz chip. Well, I would suggest reading the exellent blog of AsereBLN, located here. He goes through the process of installing and patching the DSDT of a Gigabyte-based board, but the standard HPET, RTC and TMR patches are equally valid for any computer, including the Dell. Then I would read the DSDT patching section of Project OS X. They have some good discussion on DSDT patching and the USB fix that I incorporated into my DSDT was sourced from that board. Once you have a good grasp of what the DSDT actually does and how to change it, you'll be well on your way.
