@missingsince - I know that clip issue all too well, sorry to hear! I got tired of it and ordered Pomona 5250, those are MUCH better than the cheap $3 clips
Bummer on the 167 error, I could keep trying if you wanted, but that is more risk on continuing using programmer and may be all for no reason if I can’t eventually bypass the lock causing error 167.
Sometimes it’s easy to find, others it looks like correct ones but never ends up being the right one 
Very odd you can dump FD/ME with jumper in place but not write BIOS region. BIOS region is the only thing unlocked in FD, both FD and ME are NO for read or write, I guess the jumper only overrides the FD locks, not the actual FPRR lock inside BIOS region.
So, we must continue with programmer for any edits, unless you want me to look again and see about giving that 167 error another try
For the actual edit you wanted, access to the other Advanced menu, please give me a zip of ALL pages of your BIOS, all menus, submenus, all root pages, all settings.
This way I can find something you currently don’t see, that you wouldn’t want or need, replace that with a link to the other advanced and then make it visible for you.
