Hmmm... with emm386: ntfs4dos uses at total of 24 MB XMS and 330k low RAM, plus 64k data area. With umbpci: only 16 MB XMS and 52k UMB space, plus 64k data area in low RAM.
Very strange. If both was on the same PC with the same NTFS drives connected, then NTFS4DOS reacts in some weird way to emm386... BUT: In both cases FreeCOM used XMS swapping and did not waste DOS RAM - only NTFS4DOS itself is to blame for being a memory hog here.
