The 7 KB footprint indicates it is using DPMS and that it had problems
to load into UMBs because there was not enough free UMB memory 
available in one continous chunk (I recall something in the area 
160 Kb that is required - this is why my INSTCDEX utility exists.)

(The 112 bytes environment footprint will probably vanish with 
future issues - not only with NWCDEX.)

Try CONFIG.SYS YEAR2000=OFF. The DR-DOS 7.02+ IBMBIO.COM hooks INT 1Ah
to correct the RTC date. 

This interferes with QEMM and many Symbios/LSI based SCSI drivers
(from Symbios, ASUS, Nomai, etc.)
