3150 not imageable

A Wyse unit sitting at the BIOS screen isn’t a good place to start. t that moment neither PXE nor CE has been invoked. So there is no easy way to flash the unit.
I will give you one way but keep in mind that this way is not foolproof.

– Open a working (!) unit and locate the BIOS chip. This is normaly the only one sitting in a socket. It is about 1cm² in size. You can pull this chip with either a screwdriver very carefully (don’t break the chip or socket) or better to use a special tool which can be bought in every electronic shop.
– Do the same with a broken unit
– Put the working chipin the broken unit
– Create a device in WDM manually and schedule a PXE job to that device
– Roll the package to boot by right clicking the job in the Update Manager
– Boot the broken unit
– As soon as the PXE request is answered and maybe 5-10 lines of code have srolled over the screen (doesn’t really matter if 5 or 10), press “Pause” on the keyboard. This imaging process will stop.
– Now pull the working BIOS chip out of the unit while it is running and put the broken one in it
– Press any key to continue imaging

I know this way sounds strange and quite dangerous but I did it myself several times without ever killing one unit. This does not mean it will ALWAYS but at least in my case I had quite a good success rate.

Background: In your case the BIOS chip is corrupted and part of the PXE imaging process of Wyse is flashing the BIOS. As we are using a working BIOS chip to boot the unit, we can start the imaging process. Then we change the chip and the process is now flashing the broken one with a new BIOS.

The only other option you would have is to send the units to a Wyse Service Center.
