Where to D/L Linux Kernel?

What Does Kernel Version Mean? Naming using [ 主版本 ].[ 次版本 ].[ 修訂版本 ]-[ 附 版本 ]. Odd minor number is testing version. Even minor number is stable version.

Prepare Your Kernel Source Code 1.You need to be root to compile kernel. #su 2.D/L kernel source code. 3.Unzip kernel source code. cd /usr/src tar -zxvf linux-2.x.x.tar.gz 4.Make the link “/usr/src/linux-2.x.x” to the kernel source directory. #ln –s linux-2.x.x linux You may have many versions of Linux source codes

make config #make config #make menuconfig #make xconfig

make config

make config(cont.) If you meet some problems. (SATA) Device Drivers ---> SCSI device support ---> SCSI device support SCSI disk support Device Drivers ---> SCSI device support ---> SCSI low-level drivers ---> [*] Serial ATA (SATA) support

Kernel Compilation 1.#make clean 2.#make bzImage 3.#make modules 4.#make modules_install 5.#mkinitramfs –o /boot/filename 2.x.x 6.(/lib/modules/)

Booting using New Kernel cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.x.x Setup your boot manager. Lilo or Grub

Grub # vim /boot/grub/menu.lst Add the following section: title linux-2.x.x kernel (hd0,0)/boot/vmlinuz-2.x.x root=/dev/hda1 devfs=mount Reboot.
