@Vladimir Murzin--thnx. for the link..really interesting it is..<br><br>@Santosh sir,<br><br>Quoting from:<br><a href="http://www.ibm.com/developerworks/linux/library/l-initrd/index.html" target="_blank">http://www.ibm.com/developerworks/linux/library/l-initrd/index.html</a><br>
<br><i>The <em>initial RAM disk (initrd)</em> 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. <b>The kernel then mounts
this initrd</b> 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.</i><br><br><br>We were just at <br>BIOS->MBR->bootloader at MBR(GRUB/LILO)-....<br><br>1.does GRUB/LILO understand/see the filesystems????<br>--so that it mounts the initrd image or the kernel image bcz. they both are in /boot(harddisk filesystems)<br>
2.does the kernel mounts initrd as root filesystem??? or the bootloader does this task??<br>
