They are the same. The mouse adapter should work with the keyboard.
As far as I know, whether that would work is a function of the keyboard
design. The colored adapter is passive, and the dual mode device does something
to determine the interface type, and then run the appropriate protocol.
There are pictures of adapters here. They're passive and just wires and
connectors to adapt to a different connector. These only work, if the chip
inside the device is dual mode. And you'd know that, if the device *came*
with the adapter. That would be the proof of dual mode. I have two mice
that came with the turquoise-green colored passive adapter, so I know
they're dual mode.

There are active adapters for the other direction, USB on the computer
side and PS/2 on the device side. This is the chip used in
the active dual PS/2 to computer USB adapter. When you get a PCI
card with PS/2 connectors on it, the PCI card may have one of these
on it as well.

It is highly unlikely you can enter the BIOS, using a keyboard connected
to one of these...)

I've never seen an active device to adapt a USB keyboard to a PS/2 computer.
It could probably be done, but the market for such a function would not
be very big.

As for entering the BIOS, when you have no PS/2 keyboard to do it with,
that could be tough. It all depends on what "BIOS defaults" are present.
If the BIOS defaults included enabling USB legacy support perhaps, then
"clearing CMOS" might put you back in control. If the defaults don't
lean that way, then you may need to borrow a PS/2 keyboard long enough
to experiment with it.
