Re: Enabling 32 bit access in Windows on Thinkpad



> 
> How exactly do you enable 32 bits processing in Windows 3.1 ?

	Go to "Control Panel", "386 Enhanced", and then click the "Virtual
Memory" button--same as you did when you created the Permanent Swap File
you described.  At the bottom of the dialog box, there is a check box for
turning on "32-bit Disk Access".  Click it.

	Do not confuse this with the newer "32-bit FILE Access" which is a
separate feature!  It can only be found in the new Windows for Workgroups
version 3.11 (do not confuse this with the "regular" Windows updated to
3.11).

	As for 32-bit Disk Access--I've never noticed any speed increase,
though I know some people who swear by it.  These are probably the same
people who carry a stopwatch into the bathroom with them to see how long
they can pee... ;)

	Probably too much.  Windows' "suggestions" on swapfile size are
always a joke.  How much actual RAM memory do you have?  That will determine
the swapfile size, pretty much.  I have 12 MB on my machine and under normal
circumstances, I wouldn't dream of having a swapfile larger than 1 or 2
MB at most.  *Do* have *some* swapfile though--it *does* help slightly in the
speed department, even if you have all the memory in the world.  I don't know
why (and it doesn't make sense)--but it does.  I've read many an educated and
intelligent Windows' users' opinion on this subject, and the brighter ones
recommend a swapfile (though small) under *all* circumstances.  Apparently
there is something about Windows' code that makes it check for a swap file
when it goes to do something memory intensive (like opening up a program--
this is especially true of a DOS window) and if there's not one to find, it
takes a bit longer.

	In my case though, I now have an 8 MB swap file in addition to my
12 MB RAM.  The reason is 1--and only 1--software package.  MathCAD 4.0 for
Windows.  It installed Win32s (32-bit extensions that make Win 3.1x run
programs that are actually designed to run under Win NT or the yet-to-be-
released Win 4.0).  For some reason, it simply *demands* a big swapfile
and while I can run it without such a large one, it then often won't let me
open up any other software!  Hence, I go along with the manual's recommendation
of having an 8 MB swapfile (which IMO is *huge*, considering I have 12 MB
RAM!) and I haven't had any problems since!  Sometimes ya just gotta
RTFM!

	Not particularly.  However, if you upgrade to Windows for Workgroups
3.11, you can then take advantage of a feature called "32-bit FILE access"
which is, essentially, a Windows-based Disk Cache, but its much faster than
other disk caches (i.e., SmartDrive) because it is 32-bit based code, rather
than the 16-bit based SmartDrive (or other disk caches loaded at DOS).  It
*is* a noticable improvement...

	As for WordPerfect--if you can afford it, upgrade to 6.0.  It has
finally ironed out the bugs that have plagued WordPerfect's Windows versions
for a couple of years now.  I think you'll like it much better.

	...or better yet, switch to Ami Pro!!  (I'm a big fan...)
