最后升级成功没，成功的话回滚一下BIOS。

Steps to attempt to recover BIOS:
1. Power off system and unplug power cable.
2. Remove side panel and locate "Boot Block Recovery Jumper" on side panel label.
3. The jumper will be on a 3 pin header where 2 of the 3 pins will be loaded by the jumper.
a. On the Z840 load the jumper on the 2 pins towards the front of the chassis.
b. On the Z440 and Z640 load the jumper on the 2 pins towards the rear of the chassis.
4. On a USB key (preferred format FAT32), with a built in LED to show activity, place the .bin file of BIOS version 2.20 or later install on the root directory.
5. Install the USB key onto the failing system, insert power and press power button.
6. When the system is powered on it should be followed by 8 beep audio code. Disregard this as this is normal behavior.
7. The USB key activity LED will begin to blink slowly then rapidly in most situations. This process will occur twice.
8. If BIOS Recovery is successful, the display will show a BIOS Recovery screen with the update in process. "Don't shut off power at this state."
9. When install is complete, the system will power off.
10. At this point unplug the power cable and USB key.
11. Return the Boot Block Recovery jumper to its original location. Replace side panel.
12. Insert power cable and press the power button. The system will come up with a black screen and shut off once, then power on by itself again and if successful the BIOS post will appear.
*If recovery steps unsuccessful replace system board.

USB key是U盘

跳线位置，看机箱盖板内侧图例，一些必要的位置会标记出来

我的是Z440，那个bin文件怎么获得，是从下载的bios的exe格式的文件解压出来的那个bin文件吗？谢谢
