The following commands/programs will be used/discussed this week:

make
cd /usr/src/linux/ (or /usr/src/linux-2.x.x)
make mrproper
make config vs. make menuconfig (gconfig and xconfig don't work ?)
patch -p0
diff and colordiff (yum install colordiff)
make dep
make clean
make zImage vs make BzImage
make modules
make modules_install
make install
lilo
grub
ldd
ldconfig and /etc/ld.so.conf
depmod -a and the file modprobe.dep (which is not in /etc)
insmod and modprobe, with modules.conf (which IS in /etc)
mkbootdisk
mkbootdisk --device /boot/newkern.iso --iso 2.6.xxxx.EL
(Make sure you get the FULL kernel version number from the /boot directory, which is the part AFTER vmlinux- and should start with 2.6, and on Centos, end with .el5)

You have recompiled your kernel. What do you do now? (how/why do you use the following). make modules
lilo.conf and the lilo program (Or Grub now)
place kernel image where?
Your computer has 256Megs of ram, yet Linux only finds 64Megs at boot up. How would you edit lilo.conf to correct that?
You want lilo to be able to load the new and the old kernel. How and why?

1. THIS IS OPTIONAL!!!
2. Run 'make xconfig' (or possibly 'make menuconfig')
3. Check out the various options
4. Why do they ask y n m ??
5. Remove things that you don't feel are necessary.
6. run make dep and make clean
7. run make zImage
8. WHERE did it stick your new kernel?
9. What size is your old kernel? How big is the new one?
10. What are modules? How do you use them?
