Boot Sector Recovery from an IDE CD-ROM
This process is almost identical to the process of Boot Sector Recovery from a USB
device, except that the BIOS image file is loaded from a CD-ROM. Use a CD-R or
CD-RW drive to burn a CD with the BIOS image file in it, and name the file
“SUPER.ROM” for the recovery process to load the file.
3.10.4
Boot Sector Recovery from a Serial Port (“Serial
Flash”)
This process, also known as “Serial Flash,” allows the user to use a serial port to load
a BIOS image for Boot Sector recovery. This feature is usually used for embedded
systems that rely on a serial port for remote access and debugging.
Requirements
In order to use Serial Flash for Boot Sector Recovery, you will need to meet the fol-
lowing requirements.
• The “Target system,” the system that needs BIOS updates, must have a serial
port and “Serial Flash” support embedded in the BIOS image file.
• The “Host system” should also have a serial port and a terminal program that
supports XModem Transfer protocol (Hyper Terminal for the Windows operat-
ing systems, and minicom for Linux/FreeSBD, etc.).
• A Null_modem serial cable
How to use Serial Flash for Boot Sector Recovery:
1.
Connect a Null_modem serial cable between the target system and the host
system that runs the terminal program.
2.
Make sure that the new BIOS Image file is accessible for the host system.
3.
Start the terminal program on the host system and create a new connection.
