Pretty sure Enhanced Mode, that only came later in Windows 3.11 for Workgroup, is the one that supported the flat addressing mode.

Enhanced mode was already in 3.0 (and I think allowed for flat addressing)

However, Win32s was introduced in 3.11 which a subset of the Windows 32-bit API from NT.

3.11 also introduced 32-bit disk access and 32-bit drivers.

Microsoft did 32-bit in steps -- it was confusing already back then.

I remember I started my internship in June 1995. We were doing stuff with this brand new thing called the World Wide Web.

They gave us a win3.1 computer and Spyglass Mosaic which required the Win32s susbsystem.

The full time guys all had a Sun on their desk next to their PC. We also had to run an IBM 3270 terminal emulator and X server to connect to the Suns. It was all so unstable. I rememember a bunch of "Win32s error" popups.

The other intern and I found a room full of decommissioned 486 machines, installed Linux and didn't tell anyone for a month. Everything worked great and then we started an assembly line of installing Linux on those old machines for all the older coworkers to take home.

IIRC a lot of it wasn't turned on by default due to hardware/driver compatability concerns, and there were articles all over the place about how to turn it on for extra performance. Essentially they used optimising tech-heads the world over as a giant beta-test group for parts of Win95's IO subsystem.
