Procedure
Step 1
Plug the USB flash drive into the server. From the command line, enter dmesg | tail. This displays the detection
information and device location for the USB flash drive.
On a single disk system it will most likely be sdb, but it may also be sdc, sdd, etc. Confirm the USB flash
drive’s device location before proceeding.
Step 2
Enter fdisk using the device path found in step 1 (for example: fdisk /dev/sdb). The command prompt
appears. Enter the print command by typing p to see details about the device
Step 3
If the partition is marked bootable by the * under the boot column, toggle the bootable attribute using the a
command and enter 1 to select the first partition.
Print the data again and you will see it is no longer bootable.
Step 4
Write changes to the disk using the w command, which also results in an exit from fdisk. Wait a few seconds
for the write to complete, and then remove the USB flash drive.

the USB plugged in.
To prevent firmware corruption, which can result in a catastrophic failure of the MCS 7890, use
of a UPS is highly recommended. The time to complete a BIOS upgrade is approximately 30
minutes.
