cannot reprogram device id and subsystem of iwl4965

[GoogleCodeExporter]

When trying to reprogram my card from IBM (8086:4230, 8086:1110) to generic 
(8086:4229, 8086:1103) I get this:

# ./iwleeprom -d 0000:02:00.0 -m -c -i iwl4965agn-generic.eeprom -D 1
debug level: 1
Using device 0000:02:00.0 [RW] PRO/Wireless 4965 AG or AGN [Kedron] Network

Any idea if these cards just can't be reprogrammed?

supermathie,

Intel 4965 often blocks it's eeprom for writing after first access.
Or even is already blocked from factory.
Yes, it may be unblocked, but for now I have no idea which register is mapped 
to this blocking.
But some cards may be successfully reprogammed.
