yes, I will check the jumper to unprotect the flash. Accourding to an1122 this should be the "temporary unprotect" by rising pin1 to 12V=VID. The block-unprotect algorithm (protect all blocks, then unprotect all) should be added to flashrom aswell so we can permanently unprotect the flash.
jep done that .. but i think you did also ?
No, not yet. That is work to do. Soldering-in the jumper is not the big deal btw.

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.

from the other tread i assume you are talking about the compaq deskpro en sff 600n motherboard which has a jumper (P34 but not mounted only pads) to connect pin1 to 12Vdc
