Im attempt to to change Device ID from 4329 to 4329 on Broadcom BCM4329 802.11n Wireless Network Adapter Cardbus inside the Netgear WNR834B v1 running dd-wrt.v24 beta. new Device ID ok but b43_srom write crc on wrong place and can not read whole/full/complete SPROM.

Any tools for linux or windows to fix SPROM or force the driver load

Im found temporary solution

Howto:
Im thinked about if sdram_init, sdram_config, boardtype, boardnum, boardrev, boardflags and .. is copy from CFE to nvram so why not test to put "srom" in nvram.
veeeeeee the worked the WLAN led light up and the WLAN works
