There is no bootloader available for at89s51(atmel version of 8051)....bcos of absence of bootloader section in at8s51....but u can always use bootloader if u have p89vrs51...this is also an 8051 based controller but it has a bootloader section in it....
A bootloader is what loads the kernel into RAM and transfers control to it from the BIOS.
launches the bootloader
You can make it the default option in the bootloader. Or you could reinstall the Windows bootloader, but it will not allow you to boot Linux without modification.

It depends on the size of the disk drive(s) and what kind of bootloader you have. With the right bootloader you can put on as many as your hard-drives can handle.
No, the iPad's bootloader is locked
No. Windows 2000 uses it's own bootloader and kernel. No component of DOS (command.com, io.sys, autoexec.bat) need be present for it to work.
GRUB is the bootloader for Linux operating systems. The bootloader is the section of code on the hard disk drive that is called and executed at bootup. It will load the operating system components and programs and start the operating system.
There is no the Linux bootloader. There are dozens of bootloader for Linux across multiple platforms. LILO, GRUB, ELILO, SYSLINUX, ISOLINUX, EXTLINUX, Das U-Boot, yaboot, SILO, Cromwell, EMILE, redboot, quik, Loadlin, Penguin, MILO, aboot, Palo, etc... are all examples of bootloaders used to boot Linux.
Sorry i don't think that's possible =(
Theoretically, almost any two operating systems can be dual-booted. The only requirement is that you have a bootloader that is capable of either loading multiple kernels, or can chainload another bootloader.
