SBM Boot Manager

Quick Start:-Directly download the self-extracting sbm.exe_(660k/Free) and run it with a blank formatted floppy in its drive. Reboot to the floppy - that's it!


This really useful program, with a tiny footprint, can generally be configured to boot up a wide range of bootable partitions on multiple hard drives, floppy drives and (BIOS permitting) CDROM drives. It may indeed be the only way to boot problematic boot CDs. It can itself be run from a boot floppy or from a HDD's MBR or from a boot CD. It can also be found as a component utility on an EBCD and on the FreeDOS installation floppy diskette. Both Linux and Windows versions are available from the SBM website.

Booting from CD-ROMs

SBM supports booting from almost all kinds of IDE/ATAPI CD-ROMs, including PCMCIA CD-ROMs. If you have a laptop with a special PCMCIA CD-ROM which has no support for booting in the BIOS, SBM can often help to boot it up.

Image Files

For those that want to use a floppy image then unzip another direct download sbm.zip_(640k/Free) and use its enclosed sbm.img file with your own software. If you want a really good and easy-to-use floppy-imaging program try Mirkes's 3.5Master_(562k/Free).

For those that want to burn an iso to a cd then unzip another direct download sbmiso.zip_(641k/Free) and use its enclosed sbminst.iso file. If you want a simple program to burn the iso with then try TerabyteUnlimited's BurnCDCC (69k/Free) or use ImgBurn (800k/Free), the successor to the burning component of DVD Decrypter. Note that if using the boot CD, created by the iso, that one cannot save any changes made to the SBM configuration at each reboot because those changes can't be saved to the CD as they can with a floppy.

User Guide

It is worth reading the sbm-user-guide.pdf (200k) for further information and advice especially if you are intending to boot to multiple hard drives. The same guide in html format can also be unpacked from user-guide-3.7.tgz (38k) from the SBM site. If you need a utility to extract the files then you could try Izarc 3.5 (3MB/Free) or WinRAR 3.51 (930k/40-day Trial).

Install onto a Floppy or Hard Drive

You can also install SBM (or get the source code) by using the original files from the SBM Download Page; (this would be the smallest download size to allow you to get started). Windows users will need to have a DOS boot floppy ready in advance. One can be prepared by unzipping the "Special Disk for BIOS Flashing"; it is only special in the sense that it contains the minimum number of files to boot to the floppy - thus leaving it the maximum available space for any utilities one wants to add to it. Othewise you can make one yourself from within Windows 9x or XP. Just choose to format a floppy in Explorer and then (a) if using Win9x ensure you enable the "Copy System Files" option or (b) if using WinXP check the box "Create an MS-DOS Startup Diskette". For other OSes you will need to prepare the floppy on a suitable PC or use the download.

Booting Linux Distros with SBM

NB that if GRUB is not directly installed to the root partition that SBM will completely ignore it how ever often one rescans the partitions and drives. This tends to happen when GRUB was originally installed onto the MBR or a floppy. We believe this to be a generalisation for any partition boot sector. If it doesn't contain proper boot code then SBM ignores it. We haven't used LILO in an age but guess that the same applies.

Widely used Source Code

SBM is used in conjunction with many boot managers such as XOSL and GAG.
