| |
Hello,
I have an EBC-2000T motherboard with 3 on-board Intel 82559 NICs.
http://www.intel.com/design/network/products/lan/controllers/82559.htm http://www.adlinktech.com/PD/web/PD_detail.php?pid=213 http://www.intel.com/support/network/adapter/1000/linux/e100.htm
Running a 2.6.14 kernel, the e100 driver refuses to load because it detects a corrupted EEPROM.
cf. e100_eeprom_load()
/* The checksum, stored in the last word, is calculated such that * the sum of words should be 0xBABA */ checksum = le16_to_cpu(0xBABA - checksum); if(checksum != nic->eeprom[nic->eeprom_wc - 1]) { DPRINTK(PROBE, ERR, "EEPROM corrupted\n"); if (!eeprom_bad_csum_allow) return -EAGAIN; }
Several people have reported the same error. Intel's Auke Kok has stated that ignoring the error is a BAD idea.

What tool is used to reprogram the EEPROM? ethtool? I suppose I'll have to ask the manufacturer for an updated EEPROM?
# ethtool -e eth0 Cannot get EEPROM data: Operation not supported
I'm not sure why I can't dump the contents of the EEPROM. Does the driver need to be loaded?
On a totally unrelated note, does the 82559 support VLAN tagging? (I believe the driver supports it.)
Thanks for reading this far.
Please note, email address is a bit-bucket. I do monitor the mailing list.
Regards.
John
