No warning that a host machine was required

Hi, I have 5 x86_64 boxes that went down with some malware that messed up my linux.
This malware is carried in usb sticks by sneakernet.
I can no longer boot live distros, the USB ports are disabled on boot.
I have partial success after copying the boot image to a sata, but other weird fails.
cannot find /usr/bin. no such file, no such directory.

So I thought that I could try a non-x86_64 board and be immune to this malware.
I did not expect to need another box to run the Unmatched.
.. Back to the drawing board.

Please warn customers of this requirement when they shop.

Thank you.

Uh, I built the thing and everything just worked.
No host machine required.
I see
HiFive Unmatched - SiFive Boards
has been removed.
It was the document that talked about needing a host machine.

Thanks,
