Unprotecting 29F002BT

[Ludwig Jaffe]

Hi,

looking for the unprotect-algorithm I found the AN1122 from ST.
The figure 4 shows a way to do this, but, how do we put VID=12V to Pin#1?
Does anybody know how this is done or if we should use the 
programmer-mode/way instaed of insystem/mode/way?

Thanks for your comments.

Attached the application-note, and the datasheet of st29F002B series.

Greetings
