Hello everyone.

When I was testing some of my Windows NT 4.0 disks, while booting of the CDs, after loading all teh drivers required to do the install, some weird patterns appears and the application report an error about the virtual CPU shutting down foran unknown reason.

What's weirder is after cheching in a other software, these ISOs works, and the same OS doen't crash when SP4 or greater is installed, by default. Also, I think that isn't a setup bug because when loaded on the other software with an different BIOS, that weird pattern doen't appear.

Here is all of my tested ISOs that are confirmed having this problem:

Windows NT 4.0 Worksation in Korean with SP1 installed onto the disc

Windows NT 4.0 Worksation in Swedish

Windows NT 4.0 Server in Swedish

Windows NT 4.0 Server in Chinese with SP1 installed onto the disc

Windows NT 4.0 Worksation in Hungarian

My French discs are not affected because the SPs installed (SP4) apparently is not affected with this problem or the "bug" (in the case of this is a bug in NT 4 that was deteced in the past).

A log file is attached in the thread.

Thank you in advance.

PS : this was run in VMware Workstation Pro 17.0, but this problem affected the 16.x version, and (if memory serves) the 12.x versions.
