Wow, you seem to have deleted most, but not all, entries for
DOS/WINOS2, and some other things. I think I understand what you
are trying to do, but it is obvious that you really don't understand
what the results are.

Your CONFIG.SYS is so messed up, that I am surprised that you
can boot, at all. A lot of the REMs really don't make much sense.
My best suggestion, is start over, with a normal install, then start
deleting things, one at a time,

else goes wrong). Still, if it does what you want it to do, I guess you
should use it that way.

It appears that you have defined two NICs. The ancient
PCNTND.OS2 driver is for an old 100 Mbs NIC. I suggest using the
network driver for the Intel 1000 Mbs NIC (the first one in the list
works well). BigIcons are also not necessary. If you don't want
those things, deselect them in the installer. Randomly REMing lines
in CONFIG.SYS is not the best approach.

The line:
SWAPPATH=C:\OS2\SYSTEM 256000 256000
is not a good idea. It says to create a SWAP file of 256000 K bytes,
and stop allocating disk space when there is less than 256000 K
bytes left on the disk that contains the file. The maximum size is
32000 K bytes, so the whole thing probably is rejected, and defaults
are used (I am not sure what the defaults might be).

I don't have the time to analyze exactly what you have done, but
the above sort of jumps out as being bad ideas.
