macluscious Posted August 25, 2011 Share Posted August 25, 2011 Flashed the custom bios, deleted the DSDT file from extra folder, but I am unable to boot as it gets stuck at the apple logo with grey screen. Once I put the DSDT file back in Extra folder only then I was able to get past the screen and get the system booted. Guess it means the patched bios is not working for me. Any suggestions? _________________________________________________________________________________________________ Update1: On my hard drive I have fully working Lion 10.7.1 (EDP 1.9) and a backup copy of fully working SnowLeopard 10.6.7 with EDP 1.8. I deleted dsdt files in both Lion and SL backup. I was able to completely load both the operating systems with out having dsdt files in their respective Extra folders. BUT I did not delete the DSDT file on my main SL partitions Extra folder. I am using Chameleon RC5 r760 version. Could this be because still the system was loading the DSDT file located in the Extra folder of my main SL partition. Quote Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted August 25, 2011 Administrators Share Posted August 25, 2011 yes i believe that rev of chame always uses the main partition which is usually the one it was installed too. Quote Link to comment Share on other sites More sharing options...
macluscious Posted August 25, 2011 Share Posted August 25, 2011 So this means Bronx its safe to say that this Bios patch is not working with D830 (Intel) machine, guess time to restore the stock one back. Or am I missing some thing? Quote Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted August 27, 2011 Administrators Share Posted August 27, 2011 well if you removed all traces of dsdt and it boots correctly then it accomplished its deed. thats all it was meant to do oh and slic injection for win 7. thats just a crc bonus.

macluscious Posted August 28, 2011 Share Posted August 28, 2011 Well it never worked with out a DSDT file for me so guess its a failure than at least for my machine. Already restored the original stock A15 back. Quote Link to comment Share on other sites More sharing options...

sturtester Posted December 3, 2012 Share Posted December 3, 2012 So I am having the same issue mentioned above. I installed the custom bios because I have not been successful in installing OS X Mountain Lion on my Dell Latitude D830. The install was getting hung after in displayed the MAC Address of my NIC and then just stopped loading. So I decided to get this a shot to see if I could get it working but after installing this new BIOS every time I boot into windows it is informing me that the system BIOS is not fully ACPI compliant and blue screens. Is there a fix for this issue yet? Specs Dell Latitude D830 Nvidia 140M 2.1 Ghz RAM 4 Gigs Quote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 3, 2012 Administrators Share Posted December 3, 2012 I don't believe there's been any work done on these Custom BIOSes for a long time. Revert to stock BIOS A16. Re: OS X installation, give the D630 nVidia DSDT a try instead of the table for D830 nVidia; you never know... Quote Link to comment Share on other sites More sharing options...
sturtester Posted December 4, 2012 Share Posted December 4, 2012 So I reinstalled the stock A16 BIOS and attempted to used the DSDT for the D630 but it halted at the same point. It keeps giving me the following warning and stops the install. "ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized" Is there any fix for this error?

Administrators Bronxteck Posted December 5, 2012 Administrators Share Posted December 5, 2012 "ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized" is normal for that model.... if you have BT and or Intel wifi shut them off in bios during install.
