@Santosh sir,

Quoting from:
http://www.ibm.com/developerworks/linux/library/l-initrd/index.html

The initial RAM disk (initrd) is an initial root file system that is mounted
prior to when the real root file system is available. The initrd is bound to
the kernel and loaded as part of the kernel boot procedure. The kernel then
mounts this initrd as part of the two-stage boot process to load the modules
to make the real file systems available and get at the real root file
system.


We were just at
BIOS->MBR->bootloader at MBR(GRUB/LILO)-....

1.does GRUB/LILO understand/see the? filesystems????
--so that it mounts the initrd image or the kernel image bcz. they both are
in /boot(harddisk filesystems)
2.does the kernel mounts initrd as root filesystem???? or the bootloader
does this task??

1. Yes, they understand filesystems. They provide their own (may be
simplified) support for access to filesystem.
2. Yes, kernel mounts rootfs from initrd as a root mount point, later
it overwrote with actual root file system
