Finally got Windows Enhanced mode to work. VirtualHDIrq=off has to be set in SYSTEM.INI otherwise it fails to reflect the hdd irq to the BIOS (sometimes it doesn't even with the setting causing it to hang and the Windows 95 setup behaves similarly).

Only works in safe mode and some remaining graphical issues but it's a start.

Maybe the text layer should be hidden automatically in 256-color mode.

Nice! smile

On NP2 (NP21NT) I can run Windows 98 SE only in safe mode.

I was able to make Win98SE work in normal mode on np21nt, just remove vrtwd.386 after setup.
And there's a romset for the PC9801BX4 floating around too.

Also, as for the CDROM swap I talked about years ago, it turns out that mame is completely missing the Sense Unit Attention/Not Ready sense codes and some opcodes of the SCSI ASC.

NT 4.0 can *almost* be installed with the latest changes. Even the FAT to NTFS conversion works! It falls apart on the GUI part of the installation, though.

Also, I had to add a 16 MB option to the driver, otherwise it would complain about not having enough RAM.
