Do not use /x /d /i with the SIPROG or you'll get the chip corrupted!

For 380xd is better to use the driven programmer because the SMbus impedance is really low. It could work with SIPROG if you have a COM port which provide a good current.

I suggest you to make the driven programmer

Heheh, I also successfully unlocked good-old-bulletproof 380xd after cmos battery failure Smile

Many thanks, everything worked exactly like in manual, except I forgot about F1 first time Laughing

And scancode button isn't too intuitive for me, because it says off, so I first assumed that conversion was already on Smile

But just because of that, I noticed one nice thing Cool

You can decode supervisor password (at least on some old models) without having to disassemble the laptop, if it boots fine (= if it isn't locked = doesn't prompt for password).
Ctrl+D is the magic keyword Wink
