Based on intel 82802ab/82802ac datasheet. There is Top Block Lock. TBL# pin disables writing of highest addressable block when it is low.
When #TBL pin was desoldered and connected to Vcc (Is it right way to put it high?) Flashing with flashrom was succesful. Verify was ok.
It wasn't possible to write that chip with flashrom or uniflash before that.
There is also WP# pin to enable or disable writing other blocks.
