Hallo Thinpaduser.

I have a T23 and a Atheros mini PCI Wlan Card. I´m not able to overwrite its EPROM because it is writeprotectet. So, at startup, there is allways the 1C90 error.

My Question is, it is possible to overwrite the EPROM of the Intel Ethernet adpter so it is named as "Other" and can I use the no 1820 program?

This problem has not been solved yet:

The patch does not seem to work with chipsets above AR5004x due to some kind of EEPROM write protection. This protection is either hardcoded into the EEPROM, thus making it impossible to be changed by software. Or the write-enable channel of the EEPROM has been disactivated. Slight chance might be to program one of the chipsets' "General Purpose Input/Output" components to activate it. Yet this would require a GPIO's output to be connected to the write-enable channel of the EEPROM (depends on the circuit board layout).

I red this toppic to and even the wiki but why isn´t it possible to overwrite the EEPROM of the Intel Enthernet Chip?
