I tried using genkernel to update the kernel, it worked but when it boots it doesnt load any of the sound modules, some net modules and some others and i still have that dhcpcd error that is on another thread

**spencerf** · 03-19-2006

after you compile your kernel you need to: (EDIT: this is only form manual kernel compile I didn't see you changed to genkernel)

Code:

make && make modules_install
mount /boot (if you have it on a seperate partition and it isn't mounted already)
cp arch/i386/boot/bzimage /boot/any-name-you-want-for-your-kernel
cp System.map /boot/System.map

nano -w /boot/grub/grub.conf
change kernel line to reflect the name you saved your kernel under

so for it's

Code:

title=Gentoo
root (hd0,0)
kernel /boot/kafka root=/dev/hda3 ro

the ro is because I have jfs as my root filesystem and kafka is the name I saved my kernel as.

**crashandburn0420** · 03-19-2006

i have an ext3 filesystem soooo i put that?

**crashandburn0420** · 03-19-2006

cp arch/i386/boot/bzimage /boot/any-name-you-want-for-your-kernel

doesnt exsist

**spencerf** · 03-20-2006

no you don't put ro when you an ext3

what doesn't exist?

Code:

cd /usr/src/linux
make menuconfig
make && make modules_install
cp arch/i386/boot/bzimage /boot/bzimage

EDIT: so you are really copying: cp /usr/src/linux/arch/i386/boot/bzimage /boot/bzimage

this should be there unless you are running gentoo64 then it the i386 probably is names differently.

**crashandburn0420** · 03-20-2006

cp System.map doesnt exsist either

**spencerf** · 03-20-2006

System.map is optional. And if by don't exist you mean when you get to:
cp /usr/src/linux/arch/i386/System.map /boot/System.map ----here. This part won't exist it is where you are copying to and the name you want. But if it doesn't exist after the i386 part then I can't help.

**loft306** · 03-20-2006

ok why dont we try this....

Code:

cd /usr/src/
ls -al (we stould see the link to the proper sources if not then correct this and make menuconfig and save )

now if /boot is on a seperate part

Code:

mount /boot
make && make modules_install install  (the last install will do all the copying to /boot for you)

then simply edit grub/lilo to add the new kernel name & save then umount /boot if a seperate part & reboot
