Customizing the splash image in GRUB

Got bored with corporate logo of your Linux distribution?

Change it..

1.The image should be of size 640x480 pixels

2.Should only have 14 colours

3.In gzipped xpm format

You can use GIMP for these modifications and save it as xpm file. Then gzip and make it splash.xpm.gz

Back up your /boot/grub/splash.xpm.gz and overwrite with your file

Note: You need root privileges

Done! Reboot and watch...

Here is my lap's bootupscreen..

Monochrome images in grey scale, red, blue or green work better than other colours. I used grayscale...

Mounting Windows partitions on CentOS 5

CentOS is an Enterprise Linux distribution based on the freely available sources from Red Hat Enterprise Linux... While installing you have to choose custom layout so that it will dual boot with windows.. In my system Windows XP, Windows Vista and CentOS5 is working together... In order to access data from windows partition and to write data you need to install a software(fuse) and also you need to upgrade your kernel to latest version... For that you can just type(yum update as root)...

Install:
yum install fuse fuse-ntfs-3g dkms dkms-fuse

Then you can mount by:
mount -t ntfs-3g /dev/??? "/mnt/???"

You can check the partition by:
fdisk -l
