BIOS Recovery failiure

I have recently tried to update the BIOS of my PC and made the motherboard UNUSABLE. :smiley: (it won’t boot…and gets stuck initailly..no display…nothing…).

When I tried to recover the BIOS , by changing the BIOS recovery jumper and inserting the BIOS flash diskette in the drive, it gives the following errors.

Initially it says that the keyboard is locked. Then,

System security - keyboard is unlocked
186 security hardware control logic error
your system is now locked.
Turn power to your system OFF and then ON.

The machine is an IBM Netvista 6842-60J. Help …

I haven’t worked on IBM PC’s specifically, but I would get ahold of them and see if they can help. Ultimately, you may have to buy a new BIOS chip, and these typically run around $30 USD.

Before we go through all that, though: if you cleared CMOS, make sure you put the jumper back to it’s original position. :wink: If this doesn’t work, get ahold of IBM and see what can be done.
