Well, the Plus! version of IE1, following the Plus! version number would be 4.40.310. However, this is 4.40.308. Would this be IE<1 then?
Edit: So, I checked the Internet Explorer page of Wikipedia and came across this: http://en.wikipedia.org/wiki/Internet_E ... y_versions
The first version of Internet Explorer, Microsoft Internet Explorer (later referred to as Internet Explorer 1) made its debut on 16 August 1995. It was a reworked version of Spyglass Mosaic, which Microsoft licensed from Spyglass Inc., like many other companies initiating browser development. It came with Microsoft Plus! for Windows 95 and the OEM release of Windows 95
So there is confirmation that this should be in the OEM image of Windows 95. I'm installing the floppy set now to check, since that is labeled OEM also. It would be nice to have a retail copy of Windows 95, however I will check the one labeled 'Microsoft Windows 95 (4.00.950) [English] (Upgrade).rar'. Do we know what the upgrade looks for when installing so I don't have to install, say, Windows 3.11?
The Internet Explorer 1.0 version number most likely refers to a pre-release version of Microsoft Plus!, albeit a very late one at that, which would explain the slight difference in build number. Most likely, it was at around the same time that that particular Build 308 of Microsoft Plus! was compiled that Internet Explorer 1.0 was finalized.
As for the Windows 95 Upgrade, as far as I know, it searches for files such as WIN.COM, and possibly WIN.CNF. I would first create a WINDOWS directory, then extract the contents of the MINI.CAB, PRECOPY1.CAB, and PRECOPY2.CAB (also PRECOPY3.CAB for versions that have one) into the WINDOWS directory, and then do the same for the SYSTEM subdirectory. Then, in the Windows directory, I would create a dummy file masquerading as WIN.COM, and I would do the same for WIN.CNF. That at least worked in one case over a year ago, and if I remember correctly, it was using the exact same procedure that I mentioned above.
Alternatively, it should be possible to edit out one of the .INF files to state a different "ProductType=" setting (the setting can be anything from 0 to 9 if I remember correctly), but you would have to first copy over the contents of the Setup files to the hard disk, since you would need to extract the .INF file to accomplish this (the extracted .INF file would need to be in the same directory with the Setup files also, which is why you would need to copy everything to the hard disk).
