Ethernet controller messages
The integrated Ethernet controller might display messages from certain device
drivers. The latest information available concerning these messages will be made
available at the IBM Support Web site at http://www.ibm.com/pc/support.
Note: See the documentation on the Broadcom NetXtreme Gigabit Ethernet
Software CD that came with the server for information about configuring the
Ethernet controller.
Recovering the BIOS code
If your BIOS code has become damaged, such as from a power failure during a
flash update, you can recover your BIOS code using the flash ROM page-swap
jumper (J50) and a BIOS flash diskette.
Note: Use one of the following methods to obtain a BIOS flash diskette:
v Use the ServerGuide program to make a BIOS flash diskette.
v
Download a BIOS flash diskette from the World Wide Web. Go to
http://www.ibm.com/pc/support/, click IBM Server Support , and make the
selections for your server.
v Contact your IBM service representative.
The flash memory of your server consists of a primary page and a backup page.
The J50 jumper controls which page is used to start the server. If the BIOS code in
the primary page is damaged, you can use the backup page to start the server;
then, start the BIOS flash diskette to restore the BIOS code to the primary page.
To recover the BIOS code, complete the following steps:
1. Turn off the server and peripheral devices and disconnect all power cords and
external cables; then, remove the cover.
2. Locate jumper J50 (flash ROM page-swap) on the system board.
