Update Soekris bios firmware from your Apple Mac OS X machine
When you are using a Soekris, a new bios is published every now and then. Because I had to search-copy-try-paste quite some time to get my Apple Mac OS X to upload the most recent Soekris (net4521) bios.
Here is what you need:
- Hardware: a USB-to-serial cable. I used a IOGear CUG232A.
- Software: a driver for that USB-to-serial cable.
- Firmware: A recent firmware for your soekris.
- Software: lsr. from the lrzsz project.
I downloaded b4501_133.bin.
The driver for the IOGear USB-to-serial cable creates a device called /dev/tty.PL2303-00002006. The Soekris will most likely run on 19200 bps. If your Soekris spits out unreadable text, try a speed like 9600. If you are able to access the Soekris bios, you can always change the serial speed using "set ConSpeed=19200" for example.
# cu -l /dev/tty.PL2303-00002006 -s 19200
