Microsoft MS-DOS 4.01 [Philips OEM] (3.5-720k)
Released in 1989 by Philips Electronics Ltd.
For Philips branded PC clones

This is an OEM release of DOS for the Philips NMS P2230 computer.
These images are from the original 720KB floppy's. Its meant for that
system but works on any x86 desktop. This version from Philips does
have a custom MBR which mentions the serial number of your copy and
the copyright.

Keep an empty floppy handy for the file copy process. MS-DOS 4
requires this for a system disk it'll create. The installation
procedure itself is fully in text and very simple.

Archive contains three 720k 3.5" floppy disk images.
