in [Compact Framework]

From: Azzi Stefano on 25 Aug 2006 10:03 How i can implement a Clean Boot on WM5? I have read info on this link http://blogs.msdn.com/ce_base/archive/2006/02/09/How_OEMs_implement_Clean_Boot_on_WM5.aspx but i don't understand. How i can implement IOCTL_HAL_QUERY_FORMAT_PARTITION? Thanks in advance.
From: " ctacke/>" on 25 Aug 2006 10:17 You don't implement IOCTL_HAL_QUERY_FORMAT_PARTITION, the OEM does. If it is implemented, then you can call it from an papplication (provided you have the privilege to do so. A huge warning on this though - if the OS itself is on a partition visible to the FSD, then you could easily format the wrong partition a completely destroy the device. I highly recommend a full ROM image backup before even thinking about trying this. -- Chris Tacke OpenNETCF Consulting Managed Code in the Embedded World www.opennetcf.com -- "Azzi Stefano" <AzziStefano(a)discussions.microsoft.com> wrote in message news:70BF677E-5691-475B-916A-8371FEB900C3(a)microsoft.com... > How i can implement a Clean Boot on WM5? > > I have read info on this link > http://blogs.msdn.com/ce_base/archive/2006/02/09/How_OEMs_implement_Clean_Boot_on_WM5.aspx > but i don't understand. > > How i can implement IOCTL_HAL_QUERY_FORMAT_PARTITION? > > Thanks in advance. > >

I should change a value in a registry and after a reboot i can call IOCTL_HAL_QUERY_FORMAT_PARTITION from my application?

From: " ctacke/>" on 25 Aug 2006 11:13 The OEM would have to put in their OEMIoControl routine support for the IOCTL_HAL_QUERY_FORMAT_PARTITION constant. You can't do it afterward, so if it's not there, you have no recourse. If it is there, you can call it through a P/Invoke to KernelIoControl. The registry has nothing to do with it. -- Chris Tacke OpenNETCF Consulting Managed Code in the Embedded World www.opennetcf.com -- "Azzi Stefano" <AzziStefano(a)discussions.microsoft.com> wrote in message news:FD74F920-3510-41CB-B756-0096E948B86A(a)microsoft.com... > How the OEM implement IOCTL_HAL_QUERY_FORMAT_PARTITION?
