Re: Re: VC on FreeDOS

Hi Eric,

> Hi, nice to hear about NDN, but...

Unfortunately I just discovered that it is NOT working ok :(
I can navigate, edit files save old and new ones, but I cannot
COPY A FILE from from one panel to the other. I belive this
is a Kernel BUG. PLEASE HELP ANYONE!

Using real mode version 2.02 with and without fdxms

I have been testing with freedos stuff only. Kernel is 2027te.
I tested with fdxms I will be making more tests in the future

I haven't tested LFN...

I am using 1Mb (in a 4Mb total 486).

 I noticed that 486.eznos.org lists the current

YES. I use disk cache in two situations: 
1) general optimizations: 1 to 3 Mb
2) to speed up large program compilation: in this case a reasonable size
is between 10 an 30 Mb !!!. Yes this very big, but it can increase second
compilation time by ONE full minute ;-)
So I believe that there can be other situations where huge cache sizes can
be usefull.

BTW, NDN,s performance on a slow machine (486 33MHz) in unbearable
withou lbacache: it is slow even when moving the file curso down...
