Thanks, I can wait.

Alain, can you switch software components one-by-one? ( MSDOS --> FREEDOS )

Next week that machine will be available for me to sit there and make
tests all day long, without disroupting anything too important.
the 16bit program itself erases the disks before writing a backup to disk?
Yes. It erases all files in the floppy disk, one by one (the function is
recursive, but in this test situations there are only a fewfiles and no
directory)
The problem never happens in the first disk and when it happens in the
followinf disks, the disks are *not* corrupted.
FreeCOM for example works OK under MSDOS if specifying a full commandline.
SHELL=A:\COMMAND.COM A:\ /P
As of my understanding od DOS, once a program is loaded, only the kernel
remains active. This is not as triky as Windows where we allways have
lots of things involved. that is why it didn't even ocur to me to make
such test.
FreeSpace is calculated with _dos_getdiskfreespace
after deleting I tried both BIOS diskreset (Int13 AX=0, Dx=0) and DOS
disk reset (Int21 AX=0d00h)
The problem happens 90% of the time in the user case. It is difficult to
reproduce, it happened once in my test machine but no more.
which means it also is difficult for any other ppl to reproduce.
Yes, that is a PITA. But I will be there testing.
PLEASE HELP. It is very frustating to remove FreeDOS after 2 weeks of
Need to be sure this is only because of the kernel.
Can the program itself even be started using a SHELL line, and so ruling
out any command shell?
shell=c:\myprog\16bitprg.exe
See above. Or am I wrong?
Thanks all,
ALain
