About the Smart Boot Manager image
|
||||
----------------------------------
|
||||
|
||||
The file `sbm.bin' that is available in this directory may be useful
|
||||
to you if you are not able to directly boot the first CD because your
|
||||
BIOS may be too old and may not support ISOLINUX.
|
||||
The file `sbm.bin' that is available in this directory may be useful
|
||||
to you if you are not able to directly boot the first CD because your
|
||||
BIOS may be too old and may not support ISOLINUX.
|
||||
|
||||
Then, instead of booting on the CD directly, you create a Smart Boot
|
||||
Manager floppy image by using the sbm.bin disk image. You can create this
|
||||
floppy with rawrite (under DOS) or with dd (under Linux). Now you can
|
||||
boot on this floppy disk and it will detect your CDROM and let you boot
|
||||
on it bypassing any BIOS limitation.
|
||||
|
||||
What is SBM ?
|
||||
|
||||
Smart Boot Manager or briefly SmartBtmgr (SBM), is an OS independent
|
||||
Boot Manager - a program that is loaded by the bios before any
|
||||
operating system and allows you to choose which operating system to
|
||||
boot.
|
||||
|
||||
SBM is included in Debian in two ways, the package bmconf allows us to
|
||||
install and configure an old version of SBM and sbm wich is the latest
|
||||
version of SBM with an installer.
|
||||
|
||||
What's the use of SBM on the CD then ?
|
||||
|
||||
SBM includes an IDE driver that allows us to boot the cds even on
|
||||
machines with a BIOS that wouldn't support booting from CD, provided our
|
||||
CDROM is an IDE one, that is, so you can make a SBM floppy and boot from
|
||||
it and then tell it to boot from your CDROM.
|
||||
|
||||
Also, there are some cases where the BIOS would allow booting from the CD
|
||||
but isolinux fails to boot from there, in this case you can either boot
|
||||
using a CD other than the first, as the others don't use isolinux, or you
|
||||
can make a SBM floppy and boot from this floppy and then tell SBM to boot
|
||||
your CDROM.
|
||||
|
||||
How do you make a SBM floppy ?
|
||||
|
||||
If you have SBM installed on a box you can run sbminst. Otherwise you can
|
||||
put the sbm.bin floppy image that we provide with our cds onto a floppy
|
||||
just like you would do with a rescue image.
|
||||
|
||||
Then, instead of booting on the CD directly, you create a Smart Boot
|
||||
Manager floppy image by using the sbm.bin disk image. You can create this
|
||||
floppy with rawrite (under DOS) or with dd (under Linux). Now you can
|
||||
boot on this floppy disk and it will detect your CDROM and let you boot
|
||||
on it bypassing any BIOS limitation.
