The 58xx has an interesting BIOS. When you get into it the top line of the screen identified it as InsydeH20 Setup Utility Rev. 3.7. In the Linux dmesg text I find the line:
DMI: clientron CedarTrail/Type2 - Board Product Name1, BIOS L800 V:3.5.21-07152014 07/15/2014
The 5848C that I subsequently got hold of had a different BIOS:
DMI: clientron CedarTrail/Type2 - Board Product Name1, BIOS L800 V:3.B0.21-05092013 05/09/2013
I also found that the BIOS on the 5848C was password protected. Trying the password 10ZIG got me in.
Hit the ESC key on power-up to get to the startup screen. This is shown below.
There are five icons shown on the screen with the currently selected one being highlighted.
The Boot Manager screen lets you pick the boot device for this particular boot. In
this particular case I've highlighted the USB pen drive that's inserted.
I find that in the Device Management screen I can do virtually nothing. The only
option appears to be to toggle the Primary Video BIOS entry between PCI and AGP.
I don't know exactly what the File explorer is looking for. This is what it shows with
a wiped SATA drive and a USB pen drive with Tinycore 8.0 installed on it.
This is the conventional BIOS setup. To get into it I had to use the default BIOS password
of 10ZIG. (Note upper case).
An example from the Boot setup in the BIOS screen. Note the option there to enable/disable
the ability to boot from a USB device.
Setting the boot order sits under the >Legacy menu item.
My 58xx came with a wiped SATA drive. From the size the thin client would have been running WES7 or WE8.
I'm so used to manufacturers like HP or Wyse who have extensive support pages from which you can download the original firmware, find updates to the firmware and the latest BIOS that the 10ZiG site comes as a bit of a shock....
The 10Zig website has no obvious download section or support contact - the only immediately obvious thing being a support FAQ that appears under the Resources tab. I note that when you mouse over the 'Contact' tab you get two drop down options: 'Become a Reseller' and 'Career Opportunities'. However, if you actually click on the tab, a new page does appear and down the page there are a couple of email addresses for support.
I spotted one entry in the FAQ:
24 I am trying to get dual HDMI monitors to work on the 58XX (L800) model, each will work but not both at the same time.
Please contact tech support for a BIOS update that will support dual HDMI monitors.
I haven't tried contacting support to see how easy it is for an individual to get hold of original firmware or a BIOS update for a one-off eBay purchase.
