9.6.3.1 Recovery Mode
Three conditions can cause the system to enter recovery mode. Pressing a hot-key, setting the
recovery jumper, and damage to both partitions of the ROM image will cause the system to
enter recovery and update System ROM without the boot-block.
• BIOS Recovery
The recovery disk must include the BIOS image file AMIBOOT.ROM. The 2 MB
AMIBOOT.ROM file may be used on a 2.88MB floppy media (to go with a 2.88 MB legacy or
USB floppy device), a USB mass storage device (i.e. a USB disk on key, must be USB 1.1
or 2.0 compliant), a USB CDROM (USB 1.1 or 2.0 compliant), an ATAPI mass storage
device, or an ATAPI CDROM or DVD.
The recovery mode procedure is as follows:
1) Insert the Recovery media with AMIBOOT.ROM into the system as appropriate
based on whatever device is used.
2) Power on system, and when progress code E9 is displayed on port 80h,the system
will detect the disk.(if there is no image file present, the system will cycle through
progress code F1 to EF.)
3) When F3 is displayed on port 80h, the system will read the BIOS image file.
4) The screen will display flash progress and show if NVRAM and CMOS have been
destroyed.
5) When recovery mode is complete, the system will halt and the system can be
powered off.
NOTE: There are three different hot-keys that can be invoked:
<Ctrl+Home> - Recovery with CMOS destroyed and NVRAM preserved.
<Ctrl+PageDown> - Recovery with both CMOS and NVRAM preserved.
<Ctrl+PageUp> - Recovery with both CMOS and NVRAM destroyed.
• Multi-Disk Recovery
With this new feature the System Recovery can be made from Multiple Floppy Disks to
support ROM image greater than 1MB.
Usage:
1) Use the SPLIT.EXE utility to split the ROM image.
Execute the following command at the command prompt:
split <File Name To Be Split> <New File Name> <File Size in KB>
For Example:
C:\split AMIBOOT.ROM AMIBOOT 1024
2) The above command will create the files of sizes 1MB each (1024 KB) with names
AMIBOOT.000, AMIBOOT.001... and so on, depending upon the AMIBOOT.ROM file
size.
3) Load the first disk AMIBOOT.000
