Hi JonF,
I have seen original txtsetup.sif
Has read and has studied the information from the reference which you have given
Also it agree with OverFlow from driverpacks.net on 80 %
My conclusions:
1. If to take the information from a file CPQ32FS2.inf
That the driver is intended for devices at which hwids
PCI\VEN_1000&DEV_0003
PCI\VEN_1000&DEV_000f
PCI\VEN_1000&DEV_000b
PCI\VEN_1000&DEV_000c
PCI\VEN_1000&DEV_0001
PCI\VEN_1000&DEV_000a
PCI\VEN_1000&DEV_0012
2. If to see original txtsetup.sif,
In it there are such records:
PCI\VEN_1000&DEV_0001 = "symc810"
PCI\VEN_1000&DEV_0002 = "symc8xx"
PCI\VEN_1000&DEV_0003 = "symc8xx"
PCI\VEN_1000&DEV_0004 = "symc8xx"
PCI\VEN_1000&DEV_0005 = "symc8xx"
PCI\VEN_1000&DEV_0006 = "symc8xx"
PCI\VEN_1000&DEV_000C = "symc8xx"
PCI\VEN_1000&DEV_000D = "symc8xx"
PCI\VEN_1000&DEV_000F = "symc8xx"
PCI\VEN_1000&DEV_0012 = "sym_hi"
PCI\VEN_1000&DEV_000A = "sym_hi"
PCI\VEN_1000&DEV_000B = "sym_hi"
PCI\VEN_1000&DEV_0012&SUBSYS_001b0e11 = "sym_hi"
PCI\VEN_1000&DEV_000b&SUBSYS_60040e11 = "sym_hi"
3. Comparing hwids it is possible to draw a conclusion that CPQ32FS2.sys partially replaces standard drivers, but not all hwids from point 2 are present at point 1, And neither I nor who another won't give 100 % of a guarantee of working capacity of the device with hwids not entering in original INF file, Only testing on real hardware can confirm it.
Look at result of my script with txtsetup.sif in this case it works duly.
PS
On 80 % I am assured that this driver completely replaces standard drivers
