  1. Sony SZ Brightness DSDT

    I just deleted _BCM, _BCL, _BQC as well as the vaio specific SBRT and GBRT (get and set brightness), and everything works as before. It seems that it's only using the PNLF device. Where are my min and max brightness values coming from, in that case?
  2. Sony SZ Brightness DSDT

    Hey all, I'm kind of new at this so please be patient (I'm running 10.6.6 on a VAIO SZ, GMA950 27a2) I got some degree of backlight control on my laptop using the 10.6.2 kexts from this website, combined with Device (PNLF) { Name (_HID, EisaId ("APP0002")) Name (_CID, "backlight") Name (_UID, 0x0A) Name (_STA, 0x0B) } This gives me a slider and fn+scroll lock and fn+insert allow me to change brightness as well. (In windows, the keys are f5, f6). This would be fine, except after the 0x3f brightness step, the brightness goes down and up again. Also, 0x00 turns the screen off completely, and I have to reboot! So, I've been trying to limit brightness between 0x01 and 0x3f, but have been unsuccessful! In ioreg (AppleBacklightDisplay), the brightness min is listed as 0x00, max as 0x80. I can't figure out where these numbers come from My understanding is that the _BCL method should determine these values, but I can have it return anything and the min and max remain the same. Then, I tried to edit IOGraphicsFamily.kext with: <key>AppleBacklightDisplay</key> <dict> <key>IODisplayParameters</key> <dict> <key>brightness</key> <dict> <key>min</key> <integer>1</integer> </dict> </dict> </dict> That didn't change it either, though I must confess to not really knowing what I'm doing. AppleBacklightDisplay's CFBundleIdentifier is com.apple.io.kit.IOGraphicsFamily, so it doesn't seem to be using AppleBacklight.kext. Does anyone have any idea where these min/max brightness levels are coming from? Thanks!
  3. Thanks for the quick reply! I'd be happy using the lower range of the slider for modifying brightness... it seems to work pretty well. Is there a way to cap the range of the slider so I don't go too low or too high? Edit: My steps in IOReg (Using Fn keys) are: 0 8 10 18 20 28 30 38 40 48 50 58 60 68 70 78 80 0 is totally off (can't turn it back on after) 8 -> 38 increasing brightness 40 brightness drop 40-> 78 increasing brightness 80 brightness drop So my brightness seems to be determined by (value % hex(40)) And that my vaio's brightness is 6-bit, but OS X thinks that it is 7-bit. This could be corrected by setting my brightness->max value to 0x40 instead of 0x80. Any thoughts on how to do this? Thanks! EDIT2: This isn't strictly true, either. 38 is less bright than 78, and 80 is brighter than 40. How confusing. In any case if I could set: brightness->min to 0x01 (from 0x00) and brightness->max to 0x3f (from 0x80) I would be golden. Any thoughts?
  4. Hey guys, I'm running 10.6.6 on a VAIO SZ440N. I have QE/CI thanks to some GMA950 drivers (27a2) for 10.6.3 provided elsewhere on the forums. I have the brightness slider working via a DSDT injection (PNFL) Device (PNLF) { Name (_HID, EisaId ("APP0002")) Name (_CID, "backlight") Name (_UID, 0x0A) Name (_STA, 0x0B) } But it isn't regular. For example:i Far left is totally off 1 over is 50% half way is 100% then back down to maybe 60-70% Then slowly back up til it ends at the right. It doesn't seem to matter if I have graphicsenabler on or off, the slider and QE/CI work. However, when I try to add the Name (_HID, EisaId ("LCD1234")) to Device (LCD), OS X will not load. Any suggestions on why my slider doesn't work properly, or why I can't add that line? DSDT with only the 2nd line is attached. Thanks!
  5. Hey everyone! I have a Sony SZ 440 with a HD audio chip (VEN: 8384, DEV: 7662) which I've determined is a SigmaTel 6.10.5614. The solution in Leopard seemed to be to patch AppleHDA to make it work, but I've found very few suggestions for 10.6. Anyone know what I can do? VoodooHDA causes kernel panic, and Az something didn't work.
  6. Hey guys, I'm new to this and could really use some help. I'm trying to install OS X 10.6 onto a Sony SZ series notebook. I am trying to follow this thread: http://www.insanelymac.com/forum/index.php?showtopic=211758 which tells me to use myhack to prepare my USB drive. I am using a 80gb SATA hdd in a USB enclosure. Basically what I do is this: Make a single partition on the drive (HFS+), with MBR instead of GUID (recommended on myhack website) Run the myHack installer mpkg. I then try to boot my notebook with this drive, and it hangs on load. No chameleon or anything. I know Chameleon will work because I've managed to run it from an [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] CD. I know I can boot from a HDD, because I put Hiren's on it with grub4dos and it booted fine. The system I'm using to prepare the USB drive is an iBook G4 800mhz running Tiger. Anyone have any ideas whats up? Is there a better method for me? Thanks!
