Wyse 5070: Firmware 


 


 

 



Power Up

If you are not using a Wyse PSU you may get a warning screen as the system powers up. My 5070 came without a PSU and the one I had immediately to hand was an HP unit. On powering the 5070 up I was presented with:

Alert! The AC power adapter wattage and type cannot be determined.
The system will adjust the performance to match the power available.


Strike the F3 key (before the F1 or F2 key) if you do not want to see
power warning messages again.
Press F1 key to retry boot.
Press F2 key for setup utility.
Press F5 key to run onboard diagnostics.

As far as I can see, if you use a non-compatible PSU the CPU clock rate is limited to 1.5GHz.

A simple way of seeing what is going on in Linux is to open two console windows. In one run the command:

watch -n.5 "grep \"^[c]pu MHz\" /proc/cpuinfo"

This gives you a window showing the current clock rates of the four CPU cores which is updated every 0.5s. These will vary but in my experience with an idle Tiny Core system may be flickering between 800MHz and 1200MHz.

Next move to the second window and run the following shell command to load up the system:

for i in 1 2 3 4; do while : ; do : ; done & done

This starts four endless loops. Each of them is repeating the null instruction (:). Each loop is able to load a CPU core at 100%.

With a non-Wyse PSU and my Tiny Core Linux system the CPU clock rates hover around 1498 MHz. With a Wyse PSU they hover around 2396 MHz and then after a while fall slightly to 2297 MHz. I assume the fall is the system throttling back a little as the CPU core temperature rises.

BIOS

On power-up the F2 key takes you into the BIOS or the F12 key to a boot menu.

If you're prompted for a password and it hasn't been changed the old default Wyse password of Fireport still works on these modern thin clients.

Wyse 5070 clear CMOS
If an unkown BIOS Administrator password is set you can clear it using JMP 1. The CMOS CLR option does just that but doesn't clear any BIOS password. To do that you need to move the jumper to the Service Mode setting and then power up the 5070.

Wyse 5070 password reset
You'll briefly see the message shown right and any password will be cleared. Power down and move the jumper back to the middle position.


The Wyse 5070 BIOS identifies itself as Dell Wyse 5070 Thin Client at the top of the screen.

The BIOS screen has lost the styling that's been with us for the last 30 or more years. There's a tree style menu on the left and a large pane on the right where the detail and help on the highlighted setting is shown. You can select options using the mouse.

5070 BIOS

My unit was running BIOS version 1.1.1. According to the Wyse support site the latest BIOS version was 1.10.2. Downloading the exe file and running it on my Windows system just got me an error message: Unable to get system information. With no OS on the 5070 that wasn't particularly helpful. Trying adding command line parameters like /help didn't change anything.

A bit of research showed the thing to do was:

  • Copy the file Wyse_5070_1.10.2.exe to a USB pen drive and plug it into the 5070.
  • Power up and hit F12 to get into the boot menu.
    Boot mode is set to: UEFI; Secure Boot: OFF; PTT is ON;
    
    UEFI BOOT:
       *PenDrive
       *FreeDOS
    OTHER OPTIONS:
        BIOS Setup
       *BIOS Flash Update
        Diagnostics
    
  • Select 'BIOS Flash Update' under 'OTHER OPTIONS'.
  • It should present you with a list of files on the USB flash drive.
  • Navigate to and select the BIOS exe file.
  • Click on 'Begin Flash Update'
Wyse 5070 Bios update

Legacy or UEFI booting?

Like with the Wyse 3040 I could not find any setting in the BIOS to enable legacy booting. It looks like with the 5070 you are stuck with UEFI booting.

Booting

As noted above, on power up the F12 key brings up the boot menu:

Boot mode is set to: UEFI; Secure Boot: OFF; PTT is ON;

UEFI BOOT:
   *PenDrive
   *FreeDOS
OTHER OPTIONS:
    BIOS Setup
   *BIOS Flash Update
    Diagnostics

What appears under UEFI boot will depend on your current BIOS configuration. What you see here ('PenDrive' and 'FreeDOS') are the result of my initial playing about with the settings.

One thing I noted whilst doing this is that the actual USB port is included in the boot path. Move your pen drive to a different USB port and you'll find that it is ignored by the BIOS.

Startup delay

If you change the amount of memory fitted to the 5070 you will find that it can take some time to get going. I assume that, on detecting a change, the BIOS runs a fairly comprehensive memory test to check out the new memory before accepting it. The first time this happened it did make me wonder if I'd fitted some duff SODIMMs and the 5070 had locked up. You just need a bit of patience.

Having fitted 16GB of RAM the Dell logo appeared after 30 seconds. On subsequent power-ups it took 6 seconds.
