[hackintoshi] How to rescue intel netcard, if broken eeprom as modify to smalltree under Linux.

Renew: 🔴 attention!!!

20190805

How to restore eeprom, I wrote above, but one important thing, binary file from ethtool command is smaller than real, cause some problems.

Here is my recommendation :

Boot to UEFI as I wrote, then follow these steps.

1)Eeupdate64e.efi -nic=X /DUMP

X is your card number.

Dump file will be MAC.EEP

MAC=mac address.

Backup this file.

Rollback is simple.

Just use UEFI.

Remember when rollback, -d must add to prevent write other MAC.

I350 4 port, just modify one port, make sure everything is fine, then do again with the other three ports.

Thanks to this guide, I made 2 intel 10Gbe worked.

🔴 this guide must under UEFI boot.

As I modify my IBM X3550 M4, first port of on board i350 4 port, failed, oh no…….

Port 1 disappeared!!!

I searched lots of websites, no use, until I found this on IBM LENOVO SITE.

After lots of tried, I did it, port 1 is back.( stupid reason)

🔴 Commands

1) eeupdate64e.efi

Find your netcard number

My i350 is 3

---

2)

eeupdate64e.efi -nic=NIC# -d IBM_FOD_i350_2-4port_Copper_NCSI_1-64a_80861521_LEDupdate.eep

🔘Keypoint

👉 NIC# means 3. (In my case)

Attention not NIC3, stupid like me, failed several times, finally I understand it just only the number, 😂

👉 eeprom, use my backup, change .bin to .eep

👉 mine

eeupdate64e.efi -nic=3 -d ibm_i350.eep

Done ✅

---

3) eeupdate64e.efi -nic=NIC# -eepromver

Check again.

👉 One last thing

-d, must use it to skip MAC address, it’s very important, or you will jump into more trouble.

Now I need help to find out exactly to modify my onboard i350.

改變eeprom的資料，源自於我需要讓網路卡被蘋果mac直接oob,然而改了好幾張之後，在不同的網卡還是遇到問題，而網路上的方法太困難而且老舊，皇天不負苦心人，終於讓我在IBM的文件找到。

不然4 port網卡就掛了1 port.

改壞時，linux是無法載入也無法看到，透過一些指令去看，的確有看到卡，但沒用。

而舊方法是去改linux驅動，整死人⋯⋯
找到拯救方法之後，利用ethtool 備份的bin去寫回eeprom，結果問題多多。

最後是用一樣的拯救方法去備份另外 port的eeprom ，才順利改回來跟原始一模一樣的eeprom 。

英文不好，但為了讓改壞的人都能找到資料，就用破英文寫了
