I send a patch to add support for the EON EN29F002NT Write, read works.
Sorry, but the data sheet says you're only doing half of the identification and this will match all EON chips.
Can you test this patch? If identification fails, can you post the output of "flashrom --verbose" ? Thanks!

The Chip is an EN29F002NT.
read, write and verify don't realy work. But i'm think the chip is destroyed. If i belief my memory, i was able to write once the chip, no more afterwards.
