What's the exact difference between the 80286 kernels(standard mode) of Windows 3.0 and 3.1? I have this strange situation that Windows 3.1 runs without problems in my emulator, but Windows 3.0 shows the boot logo, then accesses the hard disk(XT-IDE BIOS is used), then when entering graphics mode it gives a permanent black screen and becomes unresponsive?

The strange thing is that 3.1 runs without problems now, but 3.0 has this strange behaviour? And both 3.0 and 3.1 in 386 Enhanced mode crash to an empty text mode screen on boot?

Anyone here has knowledge on Windows 3.0 and 3.1?

I only use MS-DOS 5.0 combined with VIDE-CDD.SYS, EMM386 and MSCDEX loaded. And 3.1 also has Smartdrive loaded.
