The EdtPRO 4.0 Millennium edition boot disk should be downloadable now.
Uploading failed three times, so I followed Master Rushi's advice and split it into three files, and sure enough it worked. But this means more trouble for everyone. I compressed it with WinRAR, so after downloading you may need to rename the files before you can extract them. The disk label provided this time is EDTPRO_0508, and the EdtUP 4.00 Millennium installation serial number is 20030508.

No! You can't extract it continuously! Get on QQ! Send it to me! I'll help you upload it!

I tried it, no problem! You definitely have to rename them first!

20035813582914640.exe → updata40disk.part1.exe self-extracting file
2003581434578598.rar → updata40disk.part2.rar
2003581471992283.rar → updata40disk.part3.rar

Damn! Why didn't you say so earlier!

You can't really blame this friend, it's all the forum's fault. When uploading, the system automatically renamed the files. This problem is very common, but when doing split archives, using .rar format for all of them seems a bit better—just my personal feeling.

I already said at the very top that they had to be renamed, you just didn't see it, right? Don't wrongly blame a good person!

The reason I made a self-extracting file was that I was afraid everyone might not have software for extracting RAR files and would have to go looking for it everywhere.

Yeah,,,, everyone should get along peacefully............ don't bicker........

If before uploading you had first compressed each of the three split-volume files one more time separately, and then uploaded those three archives, then the original split-volume state could have been preserved. The system's automatic renaming during upload would only change the names of the three archives, while the split-volume state and original filenames inside the archives would not be affected. After downloading, you would only need to extract them into the same directory, without renaming, and then do the merge operation.
I wonder if I've made myself clear?

I made version 3.0 when I was a sophomore in college. Although it's something old from a few years ago, it's still worth referring to. Version 3.0 has quite a few errors (for example, when detecting a RAM Drive, the floppy disk write-protect has to be turned on; the anti-CIH code has expired; and the biggest mistake is the lengthy graphical generation, which made the files very large even though it was actually completely unnecessary), so I recommend everyone download version 4.0. Version 3.0 is for reference only. Click to download version 3.0 (you must rename it after downloading)

I had intended to solve the problem that the anti-CIH execution code in EdtUP version 4.0 had expired, so I added in the half-finished version 4.5 I was making. As a result, during the EdtUP installation process, it caused misleading environment-variable errors in the first two options, so I am hereby correcting it. Just overwrite the original files under A:\EDTPRO\PRODUCTS with the three CAB files extracted from it, and the original functions will run normally.

The reason I compiled it this way was that not everyone wants to go through a long and complicated boot process,
and I also didn't add third-party software to the boot disk. I think it's better to make the boot disk and the software disk separately.

Version 5.0 will include a version signature:
