On my system the
10 07 2009If further changes are needed, for example the PCI product ID, the command ssbsprom i ssb_sprom_copy PAs an example, let us suppose that you have purchased Dell minipci card to use in an HP laptop. If you are unsure and dont know what we are talking about here, always build both b43 and b43legacy and firmware for both too. For this device, one would use SSB_SPROMfind sysdevices name ssb_sprom In the name above, the sequence states that this device is attached to the 0th PCI bus via bridge 0d.
For systems with more than one SSBbased interface, there will be such string for each, and the command that sets the SSB_SPROM symbol will have to be changed. Once the SSB_SPROM variable matches the path to ssb_sprom for your device, working copy of the sprom contents with sudo SSB_SPROM > ssb_sprom_copyYou look at the contents of your sprom from the sys file system. On my system, the first line of such output for my interface is 0400. 0 Network controller Broadcom Corporation BCM94311MCG wlan miniPCI rev 02.
grep 0400. 0echo SSB_SPROMOf course, the 0400. 0 needs to match your system, and check the output value to determine that there is single instance of sys… and that the path matches the device whose SPROM is to be changed. You are then ready to rewrite the sprom with sudo cp new_ssb_sprom_copy SSB_SPROMOnce again, you are urged to be absolutely certain of the contents of the working copy BEFORE taking this step. If not, adjust the string after grep accordingly. If not, then it will have to be reloaded as discussed above.
If not, adjust the string after grep accordingly. grep 0400. 0echo SSB_SPROMOf course, the 0400. 0 needs to match your system, and check the output value to determine that there is single instance of sys…, you proceed. CompaqHP laptops where the BIOS checks these at boot. If you are unsure and dont know what we are talking about here, always build both b43 and b43legacy and firmware for both too. The file path for the sprom contents depends on the bus layout of the specific computer being used and will be something like is not recommended that you try to type the name.
