Quick Q...

When you reset the bios by shorting jumpers or what ever you do...
does it reset the Bios password...

As always, "maybe". :D

Some laptop manufacturers have tried to give owners a little bit of protection from that major world economic sector -- laptop thieves. I'm pretty sure Compaq did it for a while (maybe still do ...). If you had such a laptop and could prove that you owned it, their service centres would reset the master password for you.

Quite often the BIOS information is now stored in EEPROM. This does not respond to simple disconnection of the battery by losing its contents ... you have to run software to change the contents. Sometimes a "dongle"
allows overriding of any passwords.

The passwords in battery-backed memory are not secure anyway ... as well as the battery removal trick, most BIOS manufacturers have well known "override" passwords.

who sells 'dongles' these days?

Those dongles would be sold only to service centres. ;-)

You can find instructions on the internet to make your own dongles... we had to do this at work because some of the Toshiba laptops we had were password protected - the dongles are easy to make too.

So much for security. :)

OK, I'll come clean .... :8}

I thought a 'dongle' was a term like a 'thingiemabob' - used in this context as a witticism.



A dongle (pronounced DONG-uhl) is a mechanism for ensuring that only authorized users can copy or use specific software applications, especially very expensive programs. Common mechanisms include a hardware key that plugs into a parallel or serial port on a computer and that a software application accesses for verification before continuing to run; special key diskettes accessed in a similar manner; and registration numbers that are loaded into some form of ROM (read-only memory) at the factory or during system setup.

If more than one application requires a dongle, multiple dongles can be daisy-chained together from the same port. Dongles are not in frequent use partly because enterprises don't like to have a serial or parallel port preempted for this use.

Maybe a candidate for WFTWE lol
