Hi All,

I wish to boot from an external usb instead of the internal one. In my
bios, there is no way to do this. Is there software or any tricks l
can use to make this possible?

Regards

No. This is fundamentally impossible, since the BIOS has full and
only control over the initial boot process.

Have fun explaining how boot managers work.

Never heard of a bootmanager, I guess.
 
Very funny Arnie. There is a boot manager that add Int13 support for El
Torito even if the BIOS doesn't.

Go ahead then guy's, tell me what a boot manager does?

A boot manager takes the place of the regular boot loader on the active
partition on the boot drive and allows control to be transferred to a
different boot loader from the one that is normally in that location, or
to the one that is normally in that location that has been
relocated.
Surely there
must be a piece of software out there that will allow you to re-boot
(warm boot) a machine from a usb port.

Nope. Can't be done without firmware support--something has to be able
to recognize that there is a bootable device attached to the USB port
and transfer control to a program installed on that device--until that
happens the contents of the device are inaccessible.

And where would that boot manager be installed to?

Just like drive overlays, any Int13 support is originally on disk (typically
track 0) but is resident in memory (typically below 640K).

Even without this technique, you can add modules to any Award BIOS. It's
just a matter of writing a USB storage stack and the Int13 interface.

The question was rhetoric. :)
