Etcher for creating a bootable USB stick with a Linux distribution on it.These are few tools you may need along the way. Note that in creating the Linux installation on this USB-stick it will probably be formatted and so you should first back up any data on it that you want to keep. One to hold the BIOS and LinFlash files and the other stick for a Linux OS that will be the environment from which the BIOS is flashed. This method should work for other Wyse models which use the USB Imaging tool platform type of installation.īefore starting you need two USB-memory sticks.

The steps below are what I went through to update the BIOS on my Wyse Z90DW from version 1.0F to version 2.0C. In my first attempts I was using version 3.1.0 of the tool. If you want to play it safe then you need to use the Dell/Wyse USB-Imaging tool version that is mentioned in the documentation for your particular model. LinFlash is pretty general tool and should work with all modern Wyse boxes, but the BIOS firmware file needs to be specific for your Thin client model. So make sure that you do download the files that are intended for your Wyse thin client. But don't worry too much, Wyse thin clients are pretty cheap on eBay if you manage to totally mess up your box. This method is a 'low-level' update which just pushes the new firmware straight to EEPROM chip. The approach below skips most (it not all) of the extra safety/signature checks which are in official Dell tools. So it seems that at the heart of the process there is a simple command-line tool called LinFlash that is doing the actual BIOS update.Ī simpler method to update Wyse Thin Client BIOSįlashing the wrong system BIOS to your box can 'brick' your Wyse thin client. Those lines stated something like 'signature mismatched' and 'LinFlash failed''.

In that log file there were two lines that got my attention.

Unfortunately the whole process seems to be buggy and can make a simple BIOS update a trial and error process.Īfter multiple failed BIOS update attempts I noticed that the Dell Linux update environment had been writing to a log file on the usb-stick. These checks are to ensure you are installing the correct patches to your system in the right order and also that your particular model has the right licence for the firmware update. As well as the firmware update the updater includes various checks.

The USB Imaging tool will install (Dell made) special Linux distro with the updates. This stick should run happily on your Wyse box - but it doesn't always. This is a Windows program that createsĪ Linux bootable USB-stick which includes all the updates together with the installer program.

Then for installing the software package(s) you'll also need the Dell USB Imaging tool. This huge 'Software' pack includes a complete embedded Windows operating system along with the small BIOS-update file. To start with, just for a single update, you are supposed to download a huge software package gigabytes in size. Updating just the BIOS on your Wyse Thin client using the official Dell/Wyse tools is a non-trivial and time consuming task as can be seen in this article: Updating a Z90D7.

The first is one that I wrote back in February 2017 thatĭescribes how to go about updating the firmware and/or the BIOS using the standard Wyse tools. What you'll find here are three approaches to the problem.

Unfortunately updating the firmware and/or the BIOS on a Wyse thin client is often not as slick as it should be. In place in case you may be able to track down the firmware elsewhere. Unfortunately Dell have now withdrawn support for old Wyse products and shut down theĪs a consequence I've removed the old now dead links in the descriptions below but left the articles At least, with flashrom, you can save a copy of what was here to start off withĪnd go back to the old version if necessary. If you update a box using the 'ThinOS' BIOS and then try and use one of the Wyse/Dell Windowsīuilds you may have a problem.
