I'm looking for ms dos 6.22 floppy images. This could take a while.

Maybe I should try qemm 8.03 from this webpage:
Afaik this software gives big memory boost, but some games will crash.
Is qemm compatible with free dos?

Found, this 800kb is eaten by emm386
Adding NOVCPI recovers 393kb of xms but ufo2 won't start :(

150kb - fine for me

Umbpci is for PII and above, 486 is not supported :(

: autoexec.bat

@echo off

: fdconfig.sys

!SET lang=EN
!set dircmd=/ogn /4
MENU 1 - Load FreeDOS with maximum RAM free, using EMM386
MENU 2 - Load FreeDOS including HIMEM XMS-memory driver
MENU 3 - Load FreeDOS without drivers

Mouse driver works fine :)
Other software like Dos Navigator and Ufo2 (terror from the deep)
works too.

In fact my problem is:
Adding lbacache could improve system performance so I could kill
aliens faster :) All I need is to recover some memory for cache.
