Chuck mentioned he world at Durango and there was a Poppy computer. I
quick Google search turned up a mention here:
https://www.nytimes.com/1983/11/30/business/sperry-introduces-personal-comp…
"Still later, they designed a 80186/80286 based 16-bit system, the Durango
"Poppy"; MS-DOS was selected as the entry operating system."
It didn't take much to find that.
The Sperry PC or the Zenith H-150 might have been early Phoenix customers
if the first Phoenix BIOS was released in May 1984. That said, it is not
exactly the answer to the topic title as there were a few manufacturer's
like Dynalogic that had a decent amount of DOS compatibility already.

entire thread for mentions of "Poppy" and "Durango" and these words
don't occur before. What is Poppy and Durango? Not everyone was
"there" and knows what you're talking about

who did
it, there. I have only print copies no scans.
I was there, doing just that. Initially, we at Durango didn't think
that strict 5150 compatibility at the BIOS level was necessary for the
Poppy. In fact, as OEMs, DOS 1.25 was delivered with only a sample
IO.SYS meant as a "skeleton". MS-DOS text mode, like CP/M, was
considered to be good enough.
In fact, MSDOS was never intended to be the ultimate target, but rather
an interim goal as we waited for Intel to complete the kernel for Xenix
on the 80286. Right from the first unit, we had sockets for both the
80186 and the 80286. Console I/O was done via serial connection.
It's a shame that few know about the early 80286 systems.
