Since the Kext Utility does not work with Catalina (32 bit App) one should rewrite this guide to use terminal commands only. It is four lines only, one to mount / write and read and three to manage the newly copied kext packages ... or did I miss a working Kext Utility Version for Catalina?
Kext Utility works fine in 10.15 and is not a 32bit app. I also wrote my guides using Catalina. Make sure you are using version 2.6.6
Sorry, I read only version Sierra and did not the download. The terminal commands worked well and since you need them too to fix owner and group it may be an alternative ... which will confuse other people then. Thanks for all the work you did!
There have been people here in the past not capable of executing terminal commands. Since in some cases I have up to 10 Kexts to be installed, I just like the k.i.s.s method. Just throw it into a program and let it handle everything.
Probably the 67xx bracket has a different larger rectangle in the middle. Just use the one on the K1100M. Disconnect it carefully completely from the card saving the black isolator strip and drive the rivets out using a hammer and a nail bigger than the holes to drive. It is far more easy then drilling. Carefully, of course...put a round small fitting tool nut below. Takes me less than a minute and it is clean. Drive direction should be obvious. You have to go the long way, first just hammer them trough on the other non glue side an then use the nail to drive them out.
Hi There,
yes the programmer clip wont work with your eeprom chip.
But tools like nvflash should work fine, I think..
Of course always backup your original vbios, multiple times..
you can use my premade win7 winclone image, i posted here above.
you can restore this using winclone, you only must have a working MacOS on your iMac to start restoring the winclone image.
Within bootcamp, you can use nvflash..
I also drill the rivets out with the X-bracket still glued to the board, because these boards have a very strong glue and is difficult to remove it.
are you using any adapters to accomplish this? From my testing, NON-Active adapters and don't work. I have to use this adapter to accomplish output https://www.amazon.com/gp/product/B00S0BWR2K and its the port closest to the firewire 800 port.
Just make sure you are using the correct eeprom definition, otherwise it will appear to flash correctly, but won't. The k2100m uses an MXIC 25l2006e but if using the CH341a software that definition doesn't show up. Instead you have to use MXIC 25L2005. Which will flash fine. Make sure you click verify after erase to verify its blank. And then click verify after flash to make sure it flashed fine.I just received the K2100m that I ordered, as well as a CH341a programmer... I’ll admit that I havent read as carefully as I perhaps should have... but was I correct when just reading the chip a couple of times and comparing the files and finding them identical I proceeded to flash the (from the first post) linked k2100 rom..? I also read the chip again after flashing and it is also identical... or was I supposed to alter the rom file in some way before flashing it?
Also, to remove the bracket from the gpu/mxm card I just used a screw (a couple of turns on it) and then applied some pressure from the front while holding it steady, repeating the same procedure in all four mounting holes, and it gave up quite gracefully
Perfect, I used flash ROM a while ago when modding the iMacs EFI. Everything looks fine.
You will have to modify your X bracket. I like to use a small Torx Screw drivers to push on one of the 4 rivet nuts from the front of the card to free the x bracket. Then drill out the rivet nuts from the back of the X-bracket.Awesome, just the installation left then
Since its birth it has been enhanced with an i7 2600s, 16gb ram, anda solid state drive along side the original (mechanical) drive... and now for some (heavy) metal (;
I hope to be reporting back with good news in a couple of days!
