Transcript of II Brief history of boot-loader
DAWN OF BOOTLOADERS●In the early days floppy boot sector and shoelace were the only linux bootloaders.Shoelace only supported minix file system.(supported by linux)
●VFS interface was added to implement other FS.
●Many new FS were developed after its introduction.
●To boot from hard disk, minix was needed to be at the root FS.
RISE OF LILO
● A bootloader was needed that would not prevent user from experimenting new FS.
● LILO was written to fill this gap , A bootloader unaware of FILE SYSTEM design.– LILO could boot boot from most disks supported by linux
kernel.
● This was very successful.● However,since Ext2 has become a des facto
standard,FS aware bootloader have been successfully tried again.
