Edited driver file doesn't install?

[omniwolf]

Hi guys,

i had a quick search and couldn't find anything.

at the company i work at, on the desktops you need to set the NIC speed manually to be 100MB Full Duplex. If you leave it as Auto negotiate, it goes really slowly.

i had a search in the actual driver .INF file, and found this:

[ParamsC]
HKR, Ndi\Params\RequestedMediaType,	  ParamDesc, , %Speed_Duplex%
HKR, Ndi\Params\RequestedMediaType,	  default,   , "0"
HKR, Ndi\Params\RequestedMediaType,	  type,	  , "enum"
HKR, Ndi\Params\RequestedMediaType\enum, 0,		 , %Speed_Duplex_Auto%
HKR, Ndi\Params\RequestedMediaType\enum, 3,		 , %Speed_Duplex_10Mb_Hd%
HKR, Ndi\Params\RequestedMediaType\enum, 4,		 , %Speed_Duplex_10Mb_Fd%
HKR, Ndi\Params\RequestedMediaType\enum, 5,		 , %Speed_Duplex_100Mb_Hd%
HKR, Ndi\Params\RequestedMediaType\enum, 6,		 , %Speed_Duplex_100Mb_Fd%

i changed

HKR, Ndi\Params\RequestedMediaType, default, , "0"

to

HKR, Ndi\Params\RequestedMediaType, default, , "6"

there was also a very similar section just below that bit, but with the heading [ParamsC100], which i changed to default 6 as well.

when i do my unattended install of windows, it goes thru and grabs these driver files and uses them to install all the drivers for the hardware of the PC. I noticed, however, that after i login in for the first time i don't have a network connection, and in device manager there's a yellow ! next to the driver (which appaers to have otherwise installed and be recognised correctly). If i go into the properties it has an error Code 10.

the strange thing is, if i uninstall the NIC (in device manager, right click and uninstall), and then i go Scan for New Hardware, it will pick it up again, and install the drivers, and it will work correctly (including defaulting to 100MB Full Duplex).

Does anyone know why it doesn't appear to work properly first time?

Thanks.

When you edit the inf file you break whql driver signing. The driver won't automatically install due to this.

ah hah.

and now for the obvious question, is there anyway i can force it to install, regardless of whql driver signing?

i have

DriverSigningPolicy = Ignore

in my unattend.txt file...

I'm having this exact same issue, does anyone have a solution? I undersatnd the need for driver signing but it seems broken that we can't make the changes that we need to set the speed properly for our networks.

delete the CAT file included with the driver, remove the reference at the top of the INF to the CAT file, and then turn off driver signing.

Thank you very much, that did the trick.
