I was almost amazed when instead of launching windows 3.1 running win.com one could run Borland DPMI host (that they used in their own 32-bit compiler toolchain), that stayed resident offering its API, and then one could run windows' KRNL386.EXE, that hooked with the DPMI host and booted windows.
- TMWNN 3y agoWhat benefit comes from this?
- jesuslop 3y agoNone concrete I can think about, apart from understanding better the innards of windows boot with a whacky experiment. DPMI was an open spec, so this validated that in principle you could write your own DPMI host to make windows think it was running on top of a protected mode whose view to clients you could control and customize. But again can't answer to what avail.
