Many cards tie the "write enable" Pin to its logic "not enabled" state
instead of connecting to the chip, so flash writes are impossible on
_most_ card types I came across. YMMV.

RTL8169 uses different addresses IIRC. Same problem with hard wired
Write Enable pin - see above.
I have still some not-really-working code from my earlier experiments. I
could read the chip-id and erase the chip - but the erase test failed
afterwards, though the cips' contents seemed to be all 0xFF.
If you are still interested: The attached .c file contains details on
how to talk to the flash chip on RTL 8139 NIC.
