IBM PC DOS 2000 2000
First you may be wondering why this archive is so big. It's because this archive contains images of all 6 1.44MB floppy disks in VFD format and IMG format, and I have a 3rd directory that has all the floppies uncompressed into a single directory. I also have a PDF of the manual which, by itself, ads over 23MB to the archive. (All of this makes for a bigger download, but it gives people more options and makes for a very complete collection.) This is the FULL INSTALL of IBM PC DOS 2000. This is not an upgrade version, and it is not just a bootable disk. Also note that this is actually PC DOS 2000, and not just PC DOS 7 with Y2K upgrade. The file dates of PC DOS 7 are 11/17/1994. The file dates for PC DOS 2000 are 4/30/1998. Finally, I placed all 6 disks onto a photo scanner, scanned the front of the disks, and I'm including a high res scan of that image in this archive. I'm also including a high res scan of the front cover of the manual. Unfortunately I could not find a PDF copy for IBM PC DOS 2000, so the PDF I'm including is for IBM PC DOS 7. However, there is no technical difference between PC DOS 2000 and 7. PC DOS 2000 was just a Y2K fix, but is otherwise identical to PC DOS 7. So the PDF I'm including is the same, it just doesn't say "IBM PC DOS 2000" on it, whereas the manual that comes in the box with PC DOS 2000 actually does say "IBM PC DOS 2000" on the cover. I believe this is the most complete package you will find for IBM PC DOS 2000.

IBM PC DOS 4.00 (06-17-1988) 4.00
This is the original release of PC-DOS 4.00. Bugs and all! It includes two 720k disk images in raw/winimage format. IBM DOS 4.00 was IBM's first in-house development effort with DOS. Most current downloads out there claiming to be 4.00, are actually 4.01. Do not confuse 4.01 with this version. IBM shipped 4.01 without changing the "4.00" version IDs, either in the kernel, the command processor, within the documentation, or even the exterior packaging. As a result, there are only two ways to tell the difference between 4.00 and 4.01: 1: IBM's floppy disk label will read "Version 4.00" or "Version 4.01" 2: 4.01 will have some files dated 08-03-1988.
