But in my case the OS on the hard disk could be Windows, Linux or x86 Solaris. A reboot is required from Linux booted from floppy/ramdisk after the hard disk has been imaged with requested operating system by a user. Because of the automated behavior of this, changing the boot sequence is not an option. That is why I am after executing real mode BIOS interrupts to load the MBR and then pass control to it. Any help will be appreciated :) Thanks Aboo -----Original Message----- From: linux-kernel-owner@vger.kernel.org [mailto:linux-kernel-owner@vger.kernel.org] On Behalf Of Alex Riesen Sent: Tuesday, September 28, 2004 8:22 PM To: Aboo Valappil Cc: linux-kernel@vger.kernel.org Subject: Re: Switch back to Real mode and then boot strap On Tue, 28 Sep 2004 20:11:59 +1000, Aboo Valappil wrote: > Basically I have a requirement of re-booting ( Without really rebooting ) > the OS from the hard disk ( even if a floppy is present or a bootable CD-ROM > is present).
