Hi I found a bug. We discussed it on alt.os.free-dos and
comp.os.msdos.programmer. I did find the version where the bug cropped up.
bugzilla is down, so I thought I would post the info here while it is fresh.

Excellent explicit advice!
I did a sort of binary search:
kernel 1.1.27 worked! loaded fdconfig.sys
kernel 1.1.33 worked! loaded fdconfig.sys
kernel 1.1.34 failed! did not loaded fdconfig.sys or config.sys
kernel 1.1.35 failed! did not loaded fdconfig.sys or config.sys
( I ended each of fdconfig.sys and config.sys with a different error
so I would know which was being used. Where it succeeded all but the
error command was successfully executed.)
So some change in kernel version 1.1.34 causes freedos to not try to
load fdconfig.sys. And remember this is from booting a CF as a "hard
drive", I have no way to know if it works from floppy or CDROM.
Various people emailed or newsgrouped me to say to try the cvs version of
the kernel.
I tried build 2035b-cvs kernel.sys. The good news is this version does not
have the problem reading fdconfig.sys.
The bad news is that this version will not write properly to my onboard
FLASH drive a: which is also my bios flash. Remember I am on a PC104, no
floppy or cd rom. It generally has just a fixed drive a: flash, but for
development I also have a compact flash slot for a "drive c:" A simple "copy
c:kernel.sys a:" seems to complete but the file is truncated (much smaller
the the original). Other file copies fail too.
So if I go back to kernel version 1.1.33, I seem to have a stable system
that reads fdconfig.sys and can write to my a: flash drive.
It seems something is still not right in the latest stable kernel cvs
version.
Thanks for the help, Steve.
