lets start from the beginning what coin and kernal did you mine and it worked?
did you download sgminer from that coin project? (could be they lightend it so it only have that algorithm in the kernel folder)
.bin file is something sgminer has in it to know how to mine a coin, if it doesn't have that .bin file for that coin then you can mine that coin/kernal
.bat file is where you put user setting and mining settings
if your missing the .bin file then its either been deleted or been removed by the people you downloaded the file from, sgminer can be downloaded in full with all the kernals and stuff from
https://bitcointalk.org/index.php?topic=632503.0 I mined ex. dgb coin algo groestl. There i have .bin ( myriadcoin-groestlEllesmeregw256l4ku0.bin ) At that time I only had two RX 480. There was no problem creating a bin file. And 4 GPUs work when there is the old .bin file.
Yes i downloaded sgminer for CHC coins.

https://bitcointalk.org/index.php?topic=422149.0It is also possible to disconnect two risers from PC boot. Create a bin and then re-enter two GPUs. I just do not want to do this with every new algorithm. So I want to know if i can create a bin file with 4 GPUs?
