Emulator crash with "Unhandled write to port 0x0096" error executing the IBM PS1 2121 Advanced Diagnostics #71

I tried to start the emulator (0.15) with the floppy image "IBM PS1 2121 - Advanced Diagnostics.img" but when I select the option "0 - SYSTEM CHECKOUT" the emulator closes shortly after displaying the message "PROGRAMS LOADING - PLEASE WAIT". I configured the emulator with the BIOS "IBM PS1 2121 - ROM.zip" and the hard disk image "IBM PS1 2121 - HDD image with Windows 3.0 (US).zip" I attach the log where the error in question appears: log.txt Thank you very much!

Port 0x96 is Adapter Enable/Setup Register. The crash is caused by an exit(1) call in systemboard.cpp line 186 that shouldn't be there. But even if replaced with a simple warning, the advanced diagnostics program won't probably work because POS registers are not fully implemented yet.

Many thanks for your technical explanation. I will try again in the next releases: IBMulator is really fun! Good job!
