Yes, I do remember about the 32-bit access, and the fight to activate it on machines that wouldn't.
For those that were too young to be there, activating "32-bit disk access" also meant bypassing the BIOS native code to access the disk, using instead Windows own code, thus not having to switch CPU mode for every block read or write. The speed improvement was a big difference.
Yep. VFAT was a bit of the much-delayed Windows 4 project that was backported to WfWg 3.11. It moved all the disk stack into protected mode, so the disk cache was managed by Windows (not DOS). More memory-efficient and faster. This is what permitted Windows 95 -- as Windows 4 was called when it shipped -- to add long filename support. DOS didn't get to access the disk at all when Windows was running, so DOS didn't have to be modified to read or write LFNs, just to ignore them, which was much easier. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.
