Keep in mind there are at least a few Intel based

They may not run MS-DOS as configured for the "standard IBM PC"
platform, but Microsoft offered OEM versions that could be configured
with the customer's own I/O routines. This was very common between
versions 1.x (1.25 was a common version) through 2.1. I have at
least one such here, complete with Microsoft's own "How to write an
I/O subsystem for DOS" documentation.
I believe that Bill Godbout offered PC-DOS for his 85/88 and 86 CPU
cards, where IBMBIO.COM had been replaced with drivers specific to
the Computro line. Microsoft was not interested in licensing small
numbers of MS-DOS, so Godbout started with a standard $40 IBM PC-DOS
package.
