Greetings!

Here are some miscellaneous questions regarding Windows 3, QEMM and DOS 5...

1) What is WINHIRAM.VXD?
I'm running Windows 3 in 386 Enhanced Mode under QEMM and everything is 
fine. However, I discovered a file called WINHIRAM.VXD that came with QEMM.
What is this thing? I have not been able to find any reference to this file
in QEMM'a manual or README file. I looked at a hex dump of WINHIRAM.VXD
and found a string that said something like "Win386 LoadHi Device". Is
WINHIRAM.VXD the Windows equivalent of loadhi.sys and/or loadhi.com for DOS?
If it is, I guess using WINHIRAM.VXD would only make sense when Windows is
run in real mode?

2) DOS 5 in HMA
Of course I ran out yesterday and picked up my copy of DOS 5 which I'm now
running in HMA. Everything works so far. I'm curious though about how Windows
handles DOS apps that use the HMA. Does Windows create virtual high memory
areas for these programs, such that there is no conflict with DOS? I would
guess that it doesn't and that programs that try to access the HMA are just
out of luck. Does anybody know?

3) DOS 5's SmartDrive
DOS 5 came with a new version of SmartDrive which is at least bigger, if not
better, than the one that came with Windows. Does anybody know what's new
and/or different in DOS 5's SmartDrive?

Thanks for any info you can provide.
