Hello!
I am trying to rule out potential issues with bios on this motherboard. The only Wyse BIOS I found is 1.26N on The Retro Web: https://theretroweb.com/motherboards/s/via-epia#bios

It does not boot however on my motherboard. My board came with the same bios version and after dumping it, I can verify that checksum is the same, but contents outside of nvram seem to differ which leads me to believe that copy on TRW is broken.

My bios however refuses to properly boot from usb despite the option being present in the bios and at some point I was getting bios checksum errors, so I wonder if my bios is not broken too.

If anyone has Wyse 941GXL bios and means to dump it, please do share it. Regular epia bios won't cut it cause it either has Ezra or Eden CPU, and Wyse board comes with Nehemiah cpu.
