“Preventing disturbances: / FydeOS do not guarantee stability; if data is lost, it’s your responsibility. / The original FydeOS kernel is already well-configured, so don’t tinker with it. / Don’t blindly copy and paste commands. / We do not provide any basic knowledge teaching. / Sound issues may be due to kernel or configuration file problems. / If you need configuration, make the changes yourself.”

» I dont know yet the advantages of brunch as I am new to this as well. So… good luck lads.
» This only works for x86 and amd64 systems not for arm single board arquitectures.

  • This is meant to add more driver compatability such as wifi sound etc… good luck.
