WinPE - SD Media card Controller

Hi Guys,

I don't have any other ideas so looking for some suggestions.

I've compiled a WinPE disk that loads a HTA application. All works well. I have the required drivers added to my wim image to enable the SD media card controller. I definitely have the correct driver for this controller. When my HTA application loads, it checks to see if there is a SD card in the bay and it reports information regarding the size and name of the SD card. For some reason this does not work. WinPE does not detect the controller or make it available after loading. If I pop-out the SD controller bay and re-insert it, WinPE detects the SD card and my application then retrieves the required info. I've tried doing a "devcon.exe rescan" on the command line but this also does not help detecting the controller.

Does anyone have any other ideas to enable this controller after loading WinPE? As a side note, this problem occurs on two other different model computers which have SD card lots. The correct drivers are inserted into my wim. Not sure if Drvload will help....have not used this for anything.

Thanks.

I have had exactly the same issue with a WinPE where I needed to detect the battery percentage. Though the driver was there I could not load the interface. And the only way to get it around was the drvload command which I executed by autostart at WinPE start.
Try it.

noxcho,

So just run drvload.exe name.inf after wpeinit or when my HTA application loads? Is drvload.exe already included in WinPE?

I will try it tomorrow and let you know. I guess it worked well for you battery info?

Thanks,

Yes, after wpeinit. And yes, getting battery status started working. Reading through forums I came to a conclusion that some drivers do not load automatically and you need to load them forcibly.

noxcho,

Well...... drvload.exe worked on 3 of the 4 models, The Fujitsu model would not cooperate. I think the problem is that the device (SD controller) requests a reboot which is ignored (and I don't want). Two Toshiba models and one ThinkPad worked just fine. Very frustrating. Also on one Toshiba model I cannot get the correct resolution to set. I think this is due to having discreet graphics compared to onboard.

Anyway...thanks for your help.
