Introduction

I strongly recommend upgrading the BIOS whenever an update is available: https://www.soekris.com/downloads.htm

Since it’s not necessarily obvious how to do it, I’ll explain the process.

Installation

A small package will be needed:

  apt-get install lrzsz
  

Upgrading

  • Connect to your BIOS monitor using minicom and run the download command:
  > download
  

Or try this if it doesn’t work:

  > download -
  
  • We’ll send the file using sx:
  $ sx -X ~/b5501_133.bin > /dev/ttyUSB0 < /dev/ttyUSB0
Sending b5501_133c.bin, 784 blocks: Give your local XMODEM receive command now.

Once completed, flash and reboot:
