Precautions when updating Windows driver
from the version X.Y.Z.470 or lower to
X.Y.Z.530 or higher [Windows only]
Windows driver version lower than or equal to x.y.z.470 (Corresponding HFCTools version is
1.0.1.19) and driver version higher than or equal to x.y.z.530 (Corresponding HFCTools version
is 1.0.2.22) use different utility program to set parameters. In this section, we call the driver
version lower than or equal to x.y.z.470 as ‘old’ driver and driver version higher than or equal to
x.y.z.530 as ‘new’ driver.
Difference in utility program between old and new version
No. Windows Driver and Tool version
Utility program
1
Driver Version lower than or equal to x.y.z.470
(HFCTools 1.0.1.19)
hfcutil.exe
hfcls.exe
2
Driver Version higher than or equal to x.y.z.530
(HFCTools 1.0.2.22)
hfcmgr.exe
hfcmig.exe
Both utility programs ‘hfcutil.exe’ and ‘hfcmgr.exe’ can modify driver parameters. On the other
hand, ‘hfcmgr.exe’ cannot handle parameters set by using old utility program ‘hfcutil.exe’. You
need to convert parameters when you update driver version lower than or equal to x.y.z.470
and version higher than or equal to x.y.z.530 using command, ‘hfcmig.exe –new’.
Refer to flow diagram in the next page for the procedure of conversion and the chapter ‘hfcmig
[Windows only]’ for details.
