YAOIS - Yet Another Irrelevant Operating System (Announce)

> where is PDOS advantage?
One claim is that public domain is in some way superior to other open or closed source. I would hope that because PDOS/386 assumes int 21 to do everything in a flat 32-bit mode, it could be made to support DOS32A style API to become useful for protected mode DOS extended apps. It also supports a minimal subset of the Win32 API already, basically just enough to run a compiler: Handle files and console output. There also is a normal PDOS version which runs normal DOS apps in a limited way.

If you limit yourself to BIOS-ignorant apps, PDOS/386 could run DOS32A style apps on UEFI-only systems eventually, by having different versions of the kernel: BIOS-based, UEFI-based or hardware-based device I/O.

My general impression is that both PDOS variants put simplicity and elegance over compatibility and I agree with you that people will not recompile their apps just to run them on yet another newcomer OS. As you compare it to NightDOS, it seems that FD32 is showing some signs of life again. Note that you could technically call everything which talks to apps and BIOS for the purpose of facilitating file access could technically be called a DOS ;-)
