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:

1

apt-get install lrzsz

Upgrading

  • Connect to your BIOS monitor using minicom and run the download command:
1

> download

Or try this if it doesn’t work:

> download -
  • We’ll send the file using sx:
