2) Is there any way to tune KERNEL ?
3) What is the basic difference between FS ?
4) Can I increase FS online ?

Hi,

1) Don't know. (I use GUI).

2) Yes, certainly. During booting with boot parameters and during compilation. You need (a) book(s) for that. Try also http://www.kernelnewbies.org/ or, if you really want it the hard way http://www.linuxfromscratch.org/ (I never did).

3) What is FS standing for? File-system? Please clarify.

don't know what information ioscan returns - but there is a bunch of information available in the /proc dir - try reading all the files in there for a start

You can probe the pci bus with
Code:
# lspci -vv
This command is really useful for customizing your kernel.
There is a similar command for the isa bus, but I'm not familiar with it.
Maybe isadump?

You can "tune the kernel" by compiling a new one optimized for your system.

You need fdisk or cfdisk to create the partitions and mke2fs to create an ext2 or ext3 filesystem.

I'm not sure if I understand your other questions.

Use the /proc interface to gather information about hardware for example the file /proc/scsi/scsi will display all attached scsi devices. search google for proc inteface, you will find it very powerfull. You can also add and remove deivices with ease.
to tune kernel run make menuconfig in directory /usr/src/linux (for most distributions)
what kind of fs r u talking about ext2?
the command mke2fs can be used to create file systems
