Hi,
In recent months I had massive amounts of corrupted files in my
portable computer (IBM ThinkPad).
It turned out to be a faulty cooler fan but, before knowing that,
I wrote to the FreeDOS discussion group, and an interesting
discussion ensued. That was just a few days ago.
The conclusion was that, in portables running any DOS, we should
always run a program such as FreeDOS FDAPM (or MS-Power), to halt
the CPU when not in use.
I tried it, and the reduction in heat generation by the CPU is
really dramatic.
However, this will work only with softwares written to take
advantage of the method.
So I set out to test the softwares I use most. With many text
editors and file managers, CPU load goes down to 1% (!) when we
are not typing anything, and about 50% even if we are typing.
But, alas, not so with DataPerfect: the CPU seems to be at 100%
power all the time.
I have read about using Tame to control the CPU usage, but I
suppose this is only for Windows users. There was also a post by
Ralph back in 2005 (".. run DP with no noticeable CPU usage when
idle"), but this was for people running DP under Linux + DosEmu.
I haven't found anything for DOS users.
Since I have been using DP on portables a lot in recent months,
and I maintain a DP network working 12 hours a day, both under pure
DOS, I'd like to ask:
(1) whether there is currently any way of making it use the CPU
less intensively when running under pure DOS, and
(2) whether it would be possible to make DP idle-aware (i.e.,
have a new version of it); it seems the required changes are small.
Regards,
Marcos
