I have recently tried to update the BIOS of my PC and made the motherboard UNUSABLE. (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. If this doesn't work, get ahold of IBM and see what can be done.
