CoffeeTime is a tool used for modifying BIOS to support newer Coffee Lake CPUs on older motherboards. It allows users to add necessary microcodes and make other adjustments to enable compatibility with these processors.

" * Many of the 100- and 200-series motherboards can run Coffee Lake processors;
* Both production and engineering Core and Xeon processors can be used;
* The modified BIOS will still support Skylake and Kaby Lake CPUs provided the 506E3 and 906E9 microcodes are left in the BIOS;
* iGPU, PCIe x16, and NVME are fully operational after the modification;
* Coffeetime v. 0.99 adds 16-thread CPU support for most motherboards. Common sense and VRM limitations still apply.
* H310C, B365, and Z370 motherboards are capable of running Skylake and Kaby Lake CPUs after a ME version downgrade and inclusion of the necessary microcodes."
"There are 4 revisions of Coffee Lake CPUs, each requiring a specific microcode." There is a link to the list in the article.
"Make sure to download a BIOS from the motherboard's manufacturer website. "
"Currently there are two automated BIOS modification tools available:
CoffeeTime by svarmod, The original guide (in Russian)
AllInOne_Tool by Revlaay, www.win-raid.com forum
This guide describes using the CoffeeTime."
"DO NOT use built-in firmware flashing utilities to flash a modified BIOS, it will not work."

Adventure: Running 8/9th gen Coffee Lake CPUs on Z170 motherboard (ASUS Maximus VIII Ranger):

"For making this BIOS flash successful, you have to use an external programmer. In my case, I used a CH341A programmer. Luckily, the Maximus VIII Ranger has a removable BIOS chip. I took out the BIOS chip and first took a dump of the existing official BIOS from the chip. This is useful to preserve your board data like serial number, MAC address, licenses etc. Once done, I used a software called FD44Editor to pull of the data and inject it to the modified BIOS file. Once done, I erased the BIOS chip and flashed the modified BIOS. In my case, the flash was not successful even after multiple attempts but I put back the BIOS chip back on the board anyway. It did not start (Q-Code 00). But this time, I used ASUS USB BIOS Flashback (since BIOS chip was empty, flashback will flash all regions including the ones which were previously locked). And success. The system booted up fine with the i5 7600K and worked as good as it did with the original BIOS. Our BIOS modding is done."
" On the 6th and 7th gen CPUs, there are two consecutive contacts on the CPU which are grounded. When you install the CPU on the motherboard, these pads make a connection with the socket pins which "tells" the board to turn on.
"On 8th and 9th gen, that contact point is RSVD (reserved). Hence I needed to connect these two pins."
"To do that, I used a copper tape with adhesive and cut that accordingly. Extreme care is required for this step to make sure nothing else is shorted. Also note that connecting the CPU pads are not necessary but shorting the pins in the socket is what does the trick." For some motherboards there are instructions to accomplish this same effect by soldering a small jumper on the M/B - this avoids modifying the CPU or socket.
