1. Fumana mofuta
Hobane mohlodi wa ELRepo ke mofuta wa moraorao, mofuta wa kgale wa kernel o ka jarollwa ka letsoho feela.
Fumana mofuta oa nalane oa kernel rpm:

3. Ho kenya khoutu ea mohloli

1. Kenya sephutheloana sa software sa mantlha
Yum kenya -y gcc etsa git ctags ncurses-devel openssl-devel
Yum kenya -y bison flex elfutils-libelf-devel bc
2. Theha bukana ea pokello ea kernel
Sebelisa bukana ea kernelbuild tlas'a lehae
mkdir ~/kernelbuild
3. Fumana khoutu ea mohloli oa kernel
Sebaka se bonahatsang sa Univesithi ea Tsinghua:

4. Notlolla khoutu ea kernel
Kamora ho e bula, kenya bukana ea mohloli:
tar -xvJf linux-4.17.11.tar.xz
Ho netefatsa hore sefate sa kernel se hloekile ka botlalo, kenya bukana ea kernel ebe u phetha taelo ea make mrproper:

5. Tlhophiso ea kernel
Kopitsa faele ea hona joale ea tlhophiso ea kernel

6. Bokella le ho kenya
Bokella kernel
Haeba o na le mochini o nang le quad-core, x e ka ba 8

Kamora ho bokella kernel, kenya: Temoso: Ho tloha mona ho ea pele, o hloka litokelo tsa motso ho phethahatsa litaelo, ho seng joalo e tla hloleha.
