I have the SanDisk's utility,bu how to use it?

[saber]

SanDisk didn't tell how to use it.
when I type ndcfwchg/? under Pure DOS, it shown as follow

/P Select Primary IO Mode
/S Select Secondary IO Mode
/I XXXX
select 16-bit Contiguous IO
Where XXXX = IO Base Address in Hex
/M XXXX YYYY
Select Memory Mode.
Where XXXX= Segment in Hex. YYYY= Offset in Hex
/1 Select Drive 1
/F Fixed Disk IO
/R Removable Disk ID
RETURN DOS ERRORLEVEL : 0->PASSED, 1->Failed.

Only /S can take the returning result: PASS; others always return error #20.

Who can teach me how to use this utility? Thanks!!!!

Best Regards
