cyclonefr Posted February 15, 2009 Author Share Posted February 15, 2009 no it doesn't work on 320MB (G80 is different)... But GTS 320MB isn't affected by the problem as far as I know. Link to comment Share on other sites More sharing options...
spanakorizo Posted February 16, 2009 Share Posted February 16, 2009 ok im ready to flash but please check my original 8800GT rom file size (extracted with nibitor) is it ok to proceed? i say this cause the mac rom is like double size AND AT LAST: after flashing what will happen when i'll boot into XP? "found new hardware" etc, or everything the same way was before flashing? please advice EDIT: i did everything with the freedos cd and at nvflash --check i see that i have:1024Kx1S , so is is ok to proceed: 1 farther question: 2D.rom with NiBiTor says "unknown rom etc" but 2D3D.rom look good and recognized like the old one should i flash with the 2D3D.rom?

Shadow_2k Posted February 16, 2009 Share Posted February 16, 2009 AND AT LAST:after flashing what will happen when i'll boot into XP? "found new hardware" etc, or everything the same way was before flashing? 3D.ROM from the first page should be the same size like yours. XP will redetect your graphics card (vendor ID changed) at first reboot. Downgrading the firmware will also disable HDCP via DVI support in Windows XP/Vista.

Shadow_2k i just finished burning the freedos boot CD , and i am ready to reboot/flash BUT with 2D3D.rom inside (cause it looked better on nibitor!) advive please asap if it will be a failure for both pc/mac so i don't proceed what do u mean HDCP will be disable? my tft 19'' monitor is connected through DVI port, will this stop work? what am i gonna lose ? ( do i need it only for Blu-Ray etc?) EDIT: flashing with 2D3D.rom everything ok removed the key from boot.plist , but osx will boot only in safe mode reflashed back to my original.rom i'm gonna try again CAN I USE THIS ROM? : http://www.neowin.net/forum/lofiversion/in...hp/t639884.html Link to comment Share on other sites More sharing options...
spanakorizo Posted February 16, 2009 Share Posted February 16, 2009 so after flashing with 3 different bios, no luck (2D3D.rom 3D.rom mp8800gt.rom) osx boots but with no qe/ci and nvidia card 32mb nvflash looked like it was flashing correctly, and everytime after --check ,the new bios was in i dunno why ofcourse i removed any nvinjekt and 8800GT key from apple.boot.plist iDeneb distro (10.5.4to 5.5) won't even boot, i managed to boot with a boot132 installation i have for testing so this would be closest to the "real" thing (updated to 10.5.6 without remove/edit anything) but still no luck any thoughts?

cyclonefr Posted February 16, 2009 Author Share Posted February 16, 2009 @spanakorizo : you still need INJECTION. For your information, PC use BIOS, not EFI, therefore the EFI rom isn't loaded/used at all on a PC and we still need injection. So no matter which rom you would try, you'd still need injection on a PC (but obviously not if you put the card on a mac pro. Link to comment Share on other sites More sharing options...
lensboard Posted February 16, 2009 Share Posted February 16, 2009 ofcourse i removed any nvinjekt and 8800GT key from apple.boot.plist Missed this, you still need the inject Link to comment Share on other sites More sharing options...
adamsweeting Posted February 16, 2009 Share Posted February 16, 2009 I just need a clarification of the above ! Since I have a dual boot (vista) can I modify/flash my nVidia 8800 512k GT Over Clocked using Nibitor or do I still need a bootable iso? If so what's the procedure using Vista/Nibitor? Thanks! John NiBitor is just the BIOS editor... to do the flash you need to boot into DOS. NVflash is a DOS program! Link to comment Share on other sites More sharing options...

spanakorizo Posted February 16, 2009 Share Posted February 16, 2009 so i must not remove the efi key at apple.boot.plist? and how am i supposed to understand the "difference"? only typically? anyway, i add the key again/flash again, and i'm gonna test a lot is it ok if i use just efi key and not nvinject kexts? EDIT: flashed again with 2D3D.rom and now i post from leopard after effects running,motion,flash CS4,a lot of apps, minimize windows etc i see no problem i'll keep it up for long time and i post my experience as i said, my problem was that after heavy use (gfx apps), osx become laggy i hope this helps things out Link to comment Share on other sites More sharing options...
thepiecesfit Posted February 16, 2009 Share Posted February 16, 2009 8800gt here boot 132 method, tried the disabler and erasing AppleUpstreamUserClient.kext . I believe it is the display driver some how not perfectly working with 10.5.6, since i get lagginess when turning on my TV connected to DVI 2 (sometimes) . The mouse still jitters for me despite the Definite fixes. No mas for me . Still looking for a fix Link to comment Share on other sites More sharing options...
spanakorizo Posted February 17, 2009 Share Posted February 17, 2009 back to windows after messing for 1 hour with heavy use of videos, gfx applications the lag return it's like when it starts u can fix it only with reboot (or log off/log in) description of the lag: slightest but u can sense it when it comes specially when minimize windows or use spaces, dashboard like osx drops frames and no fullframerate is used when it boots is super fast (if it was laggy from the 1st boot i would accept it) i will make a video with osx how fast it is when it boots and the lag after Link to comment Share on other sites More sharing options...
spanakorizo Posted February 17, 2009 Share Posted February 17, 2009 NewJ_Project_1.mov beggining is when osx boot and u can see how fast it is (sorry for bad quality) after 25'' i captured small video with lag windows minimize drops frames and in order to feel good again it needs reboot or logoff EDIT: after flashing again with the mp8800gt.rom and full testing on 10.5.6 boot132 partition i see no lag i had open like 20 apps together (photoshop,illustrator,after effects,motion,final cut,poser,soundbooth,soundtrack pro,quicktime,itunes,dreamweaver,iphoto,iweb,idvd,imovie .. .. ) and there was no problem this test installation is in a very old 80GB ide disk osx now feels stable like hell! carbon copy and i'll move it to the raptor Link to comment Share on other sites More sharing options...
thepiecesfit Posted February 17, 2009 Share Posted February 17, 2009 So the only solution is the update the eprom on the card? Does it still work in windows ? Link to comment Share on other sites More sharing options...
spanakorizo Posted February 18, 2009 Share Posted February 18, 2009 for the 8800GT i would say yes i reflashed before just for checking back to the original bios and i had the lag, even with the disabler.kext (dunno why) then reflashed back to the mac rom and lag is gone Link to comment Share on other sites More sharing options...

iamhappy Posted February 21, 2009 Share Posted February 21, 2009 You guys should just use the provided disabler.kext. No reason to flash your cards now. Thanks !!!!! alot! But i don't get it 100% (though i thought that my hours of research at least provide full "how to install a kext" knowledge:) Problem is: I installed it with kexthelper. Rebooted with -f flag. System Profiler now shows Disabler.kext loaded under Extensions-Tab, but there are still AppleIntelCPUPowerManagement and AppleUpstreamUserClient in the list.... I had a CPUPowermanagentDisabler.kext (not sure about the exact name) too, but i read elsewhere you have to delete it, after installing Disabler.kext - deleted, again repaired permissions, booted with -f . Still those not wanted kexts show up in SystemProfiler. This drives me CRAZY. PS: I THINK (can't fully remember) it used to work, but i reinstalled Combo 10.5.6 + all other updates that came after the 10.5.6 release with Pacifist using "update" yesterday. (still trying to fix that "Screenflow won't launch + no crashlog issue). Now my above described method of installing the Disabler.kext which blocks those 2 kexts doesn't work (cause i assume they are loaded since showing up in SystemProfiler / Extensions) Link to comment Share on other sites More sharing options...
iamhappy Posted March 5, 2009 Share Posted March 5, 2009 No clue what i did in the meanwhile AppleUpstreamUserClient.kext is gone under System Profiler/Extensions BUT AppleIntelCPUPowerManagement.kext is still in the list.... Link to comment Share on other sites More sharing options...
Nemskiller007 Posted March 5, 2009 Share Posted March 5, 2009 Sorry but i have MAC OS Retail Leopard X.5.6 and i don't have AppleUpstreamUserClient.kext, i can't find it !!! But i have lags with Itunes and Quicktime.... I have a Geforce 9800 GTX+ what i have to do so ? Link to comment Share on other sites More sharing options...
secros Posted March 5, 2009 Share Posted March 5, 2009 Same technique, fixed. thanks! another successful flash here.... now updated to quicktime 7.6 and system runs without mouse lag my card is Foxconn 8800GT 512MB how to- 1. Use HP USB DOS Disk to boot 2. "NVFLASH --check" to check if rom size fits 3. "NVFLASH --save old.bin" to save original rom. 4. "NVFLASH -4 -5 -6 MP8800GT.rom" to flash there seem no any noticeable difference from original bios(from boot to leopard, I didn't try windows yet) Link to comment Share on other sites More sharing options...
