ATI HD 2600 PRO WINDOWS 7 64 BIT BOOTCAMP DRIVER ERROR

sorry to bombard you will multiple updates to this post but ive had a lot of revelations as you can see and feel we are so close and on the right path to fixing this once and for all. i am determined to get this gpu working so that i can continue to play games like i did in xp.

check this site out,sounds like a similar problem and enforces my theory about changing the device id to match that of the true ati radeon hd 2600 pro NOT the mobility one that is either built in or was installed by the leopard bootcamp 2.0 driver package. the hardware ids theory may work and do the trick to change the actual device id but its a longshot. i poked around in the device manager and went under view option and selected by connection,i clicked under the first intel thingy and kept following it until i could see the driver for the gpu,when i got there it said something along the lines of Intel Mobility something.... if we could hack that with someone's windows 7 64 bit driver,then the system would recognize the card for what it truly is,not apple underclocking it by installing this outdated(2007) driver so that we want to kill ourselves to fix it! they simply want us to buy more newer macs.

here's the link

HOLY ****** ****! i think i found what we are looking for!!!!!!!!!!

this program can edit the BIOS of radeon gpu's!!!! it will even allow us to change the device id as i was thinking earlier! we can simply copy/paste the device id string from my xp working driver into the mobility bios and it shopuld think for real that it is definitely an ati radeon hd 2600 pro ,there will be no trace of the mobility xt device id! i will attempt to do this but i will definitely need you help! we ust do this for the mac community!! they need us,we need us!

not really intimidating at all. ithat program is very clear in what it asks you to fill in for the specs of the card that you want it to be set to. the only thing i am eworried about it at the end there is an option that says "flash to the card" im scared that if i flash a new bios to it,on the mac side things could get screwed up. i think the best plan of attack is to edit the string so that it either matches my xp device id that worked or just edit the actual numbers for the device id. meaning instead of "dev 9583" i would change it "dev 9589". if you look in system profiler on the mac side,you will see the device id is et to 9583,so in theory your script was perfect to identify our cards on the windows side,but obviously thats not working bc when it matches to that device id it reads the mac underclocked bios and sets it as a mobility card,even if you uninstall ALL dsiplay drivers and reboot,it automatically downloas the Mobility XT drivers,based on what its determining from the bios. by why? Why?? would my xp drivers say dev 9589 and NOT 9583??? maybe because when we did the trick in windows xp,it not only updated the card correctly,but also overwrited the card Bios in the windows side,making it always recognized as a true radeon hd 2600 pro and not any trace of mobility. if that doesnt work, i will then screw with the bios and set the settings as best as we can. actaully if you go to that link i posted with the program that does it, there is a tutorial on how to do everything!!!!

as for your last comment,im not sure that woud do anything,since i have already used a ton of modded drivers,and the original mobility driver would only take us a step backwards. those guys dont really explain the procedure well they say they uninstalled drivers with driver sweeper,installed mobility drivers,then i get confused. not really a solution or if it is,there not telling the whole story. also like i said before we cant even get to that point bc the second i unistall all drivers it automatically reinstalls the mobility driver. unless we were in safe mode...hmmmmmm.....

thanks hatter but we have tried multiple drivers modded and not modded,still all produce either the mobilty xt version with a weak pfs benchmark or a display name of the correct ati radeon hd 2600 pro but still with the same weak benchmarks,this must be because the device id needs to be altered so that windows knows its a desktop card and not this mobility card at the root. @drbst,i just tired my replacement string from the xp driver (ati2mag_RV630, PCI\VEN_1002&dev_9589) and saved it to both of the cog files,then did the update driver as we did before but with the xp strings saved. here's the funny thing,it installed properly,still says ati radeond hd 2600 pro,but when i run the benchmarks i get the exact same results. and i if i check under driver details tab and hardware ids tab,it still shows the mobility device id (blah blah blah DEV_9583) this reinstates my theory that we must change or alter the bios of the card at the root so windows definitely thinks its the correct card and not basing its knowledge off of the mobilty Device id apple's driver has installed. i was playing around with that ati bios tool,but ii can seem to locate where the actual bios is on the C drive/ do you know where it is??? i used the tutoiral but i think it assumes you know or have download a replacement bios for the correct card from ati. **** it! i wish somebody on here would comment who knows a lot of gpus hacking their bios's and can help us get this thing working right. we need those extra 10 fps to even have ahcne at playing today's game at even reduced settings

ok so i tried uninstalling the display driver back to default vga mode,turned off windows updates,reatsred both way ways normally and in safe mode and still both times it automatically installs the mobility xt driver!! ***? this has got to be bc at the root it is detecing the mobility card from the device id. we must edit it to the correct one or we have no chance at getting this to work like it did in xp. i am seriuosly thinking about yet again reverting back to xp just to get this fixed again and so i can play games at all. let me know if you guys can figure this out before then or at the least i could always just restore windows 7 from winclone and conitue where i left off.

@drbst i just reinstalled sp3,succesful winclone resotre yet again even with lion. i just installed the latest windos xp 32 bit ati radeon hd 2600 pro driver,all is working fine as it did when i used to have xp before lion. i will now run that benchmark program and display the results for you. if its higher than 93,everything is back the way it should be.

get this i benchmarked it with exact sma eprogram,the result is 92 !!!! 92???????? thats 1 fps less than with the mobility one in windows 7. *** is going on?????????? i am copying the sets of older working flawlessly drivers from my orignal 2 years ago xp image. i will try to manually install them when winclone finishes making a backup. it could be that the newer most updated 7/2011 drivers even for windows xp 32 bit are whats casuing our errors in both windows systems. i guess thats why they have a rollback driver option in the even the new one blows! hopefully,hopefully im praying that when i install the outdated but used to work flawlessly display drivers,it will give me a much higher fps. if not,it could be the benchmark program or some other windows screwup. i do remember after updating that display driver(original) to the newer display driver(but not the latest 7/2011 obviously) there was a performance drop at times. i should have rolled back the driver then! if thats the case i will install the very first working correct awesome fps driver and never update again either automatically or manually. this is just to hold me over until i can buy a new mac with way more power at least in the graphics department. do you know anyone looking to sell a new or used killer imac at the least??? do you have any laying around? i can easily use time machine to copy lion to the new mac,and then use winclone to restore windows xp and 7,done no more graphics issues,i dont think with a 1 gig radeon 5970 or higher and not this supergay radeon hd 2600 pro(256 mb)
