This section is to state the important features, EWF and HORN, provided in windows XP embedded. 5.1 EWF EWF stands for Enhanced Write Filter. It provides an upper filter in the storage device driver stack that redirects disk write operations to volatile (RAM) or non-volatile (disk) storage. EWF protects a volume from write access. The benefits are as the following. Write-protect one or more partitions on your system. Enable read-only media, such as CD-ROM or flash, to boot and run. Prolong the lifespan of write-sensitive storage, such as CompactFlash. TPC-1070 XPE provides EWF RAM RDG mode on system partition. All wirte to system partition will be redirected to RMA once this mode is enabled. This mode is manually enabled by customers after they finish all their changes on system such as installing their applications or adjusting system setting. Advantech provides a pair of utilities to operate EWF, OSLock and OSUnLock. The setting is stated in the section later. 5.2 HORM HORM stands for Hibernate Once Resume Many. In HORM environment, a single hibernation file is used to boot the system repeatedly. To set a HORM environment, please follow the steps below. Please make sure EWF is disabled. You can run OSUnLock to disable EWF. Enable hibernation support: Run ‘power options’ in control panel, and then select ‘Enable Hibernation’ in hibernation pane. TPC-1070 User Manual 36 Enable EWF: Run OSLock, and then system reboot automatically. Open those software that customers want to directly use after system resume from hibernation. Hibernate via Advantech HORM utility: Please Click Start Menu->All Programs->Advantech->HORM HORM environment remains all along unless the following events occur: Run EWF commit command (ewfmgr c: -commit) and then reboot system. Select “Discard hibernation file” by clicking F8 when system is starting up Also, HORM cannot fit your system if free space in C partition is not enough. The hibernation file required is dependent on the RAM size you use on the system. In other words, the hibernation file is 512MB that is the same as memory size used on TPC-1070H-P1E or TPC-1070H-C1E. 5.3 Advantech Utilities TPC-1070 provides the useful utilities for users to configure the HORM and EWF. 5.3.1 Version Information Start menu-> All Programs -> Advantech This states the current XPE runtime information including hardware platform, version, build number, release date, XPE QFEs installed in component database and XP Pro Patches you installed manually. 37 Chapter 5 5.3.2 OSLock and OSUnLock The two utilities assist users to enable or disable EWF. Please go to Start Menu-> All Programs-> Advantech. The default setting of EWF is disabled. Users can protect C partition from any disk writing via OSLock that is to enable EWF RAM REG Mode. In this mode, any changes on C partition including modification on files or registry will be redirected to memory, thus these changes will be discarded in the next system startup. To exit this environment is via OSUnLock. Please visit MSDN website for further information about EWF. 5.3.3 HORM This is to create HORM environment. Please go to Start Menu-> All Programs-> Advantech. This utility firstly dismounts all local physical volumes that are not protected by EWF. It requires users to input the volume list. Please follow the steps before running this utility to create full HORM environment.

You can access it through WIN32 API. TPC-1070 provides a WDT driver to allow users to enable/disable the Watchdog timer. The driver name is “WDT1:”. Programmers must open this driver before using the resources. Then programmers can use DeviceIOControl functions to enable/disable Watchdog timer. The introduction below includes the DeviceIOControl, the definition of the parameter and an example. B.1 DeviceIOControl This function sends a control code directly to a specified device driver, causing the corresponding device to perform the specified operation. BOOL DeviceIoControl( HANDLE hDevice, DWORD dwIoControlCode, LPVOID lpInBuffer, DWORD nInBufferSize, LPVOID lpOutBuffer, DWORD nOutBufferSize, LPDWORD lpBytesReturned, LPOVERLAPPED lpOverlapped ); Parameters: hDevice [in] Handle to the device that is to perform the operation. Call the CreateFile function to obtain a device handle. dwIoControlCode [in] Specifies the control code for the operation. This value identifies the specific operation to be performed and the type of device on which the operation is to be performed. No specific values are defined for the dwIoControlCode parameter. However, the writer of a custom device driver can define IOCTL_XXXX control codes, per the CTL_CODE macro. These TPC-1070 User Manual 44 control codes can then be advertised, and an application can use these control codes with DeviceIoControl to perform driverspecific functions. lpInBuffer [in] Long pointer to a buffer that contains the data required to perform the operation. This parameter can be NULL if the dwIoControlCode parameter specifies an operation that does not require input data. nInBufferSize [in] Size, in bytes, of the buffer pointed to by lpInBuffer. lpOutBuffer [out] Long pointer to a buffer that receives the operation.s output data. This parameter can be NULL if the dwIoControlCode parameter specifies an operation that does not produce output data. nOutBufferSize [in] Size, in bytes, of the buffer pointed to by lpOutBuffer. lpBytesReturned [out] Long pointer to a variable that receives the size, in bytes, of the data stored into the buffer pointed to by lpOutBuffer. The lpBytesReturned parameter cannot be NULL. Even when an operation produces no output data, and lpOutBuffer can be NULL, the DeviceIoControl function makes use of the variable pointed to bylpBytesReturned. After such an operation, the value of the variable is without meaning. lpOverlapped [in] Ignored; set to NULL. Return Values Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError. 45 Appendix B B.2 How to Use the Control Code There are 6 control codes for the operation codes in the WDT driver. IOCTL _WDT_ENABLE: Enables the Watchdog timer on your application. By default, if the Watchdog timer is enabled, the WDT driver will automatically trigger itself after the specified period and your application does not need to trigger the Watchdog timer in this situation. lpInBuffer : unused. nInBufferSize: unused. lpOutBuffer: unused. nOutBufferSize: unused. IOCTL _WDT_DISABLE: Disables the Watchdog time on your application. lpInBuffer : unsed. nInBufferSize: unused. lpOutBuffer: unused. nOutBufferSize: unused. IOCTL_WDT_STROBE: Triggers the Watchdog. If your application uses IOCTL_WDT_ENABLE to enable the Watchdog first and then sends IOCTL_WDT_REBOOT to the WDT driver, your application must trigger the Watchdog once during the Watchdog timer period. If your application has not triggered at the specified period, the device will reboot automatically. lpInBuffer: unused. nInBufferSize: unused. lpOutBuffer: unused. nOutBufferSize: unused. TPC-1070 User Manual 46 IOCTL_WDT_GETTIMEOUT: Gets the Watchdog time setting. lpInBuffer: unused. nInBufferSize: unused. lpOutBuffer: The DWORD pointer to your Watchdog time setting. The Watchdog time setting is just a number. 0 means 2 seconds, 1 means 5 seconds, 2 means 10 seconds, 3 means 15 seconds, 4 means 30 seconds, 5 means 45 seconds and 6 means 60 seconds. The default setting is 5 seconds. nOutBufferSize: unused. IOCTL_WDT_SETTIMEOUT: Sets the Watchdog time setting. lpInBuffer : The DWORD pointer to your Watchdog time setting. The Watchdog time setting is just a number. 0 means 2 seconds, 1 means 5 seconds, 2 means 10 seconds, 3 means 15 seconds, 4 means 30 seconds, 5 means 45 seconds and 6 means 60 seconds. The default setting is 5 seconds. nInBufferSize:.unused. lpOutBuffer: unused. nOutBufferSize: unused. IOCTL_WDT_REBOOT: If you want your application to trigger the Watchdog by itself, please use IOCTL_WDT_REBOOT to notify the WDT driver. Otherwise, the WDT will trigger itself automatically. lpInBuffer :unused. nInBufferSize: unused. lpOutBuffer: unused. nOutBufferSize: unused. 47 Appendix B B.3 Examples #define WDT_CODE(ID) CTL_CODE(FILE_DEVICE_UNKNOWN,ID, METHOD_BUFFERED, FILE_ANY_ACCESS) #define IOCTL_WDT_ENABLE WDT_CODE (0x900) #define IOCTL_WDT_DISABLE WDT_CODE(0x901) #define IOCTL_WDT_STROBE WDT_CODE(0x902) #define IOCTL_WDT_GET_TIMEOUT WDT_CODE(0x903) #define IOCTL_WDT_SET_TIMEOUT WDT_CODE(0x904) #define IOCTL_WDT_REBOOT WDT_CODE(0x905) // for compatibility reasons, you can define IOCTL as below: // #define IOCTL_WDT_ENABLE 0x1001 // #define IOCTL_WDT_DISABLE 0x1002 // #define IOCTL_WDT_STROBE 0x1003 // #define IOCTL_WDT_GETTIMEOUT 0x1004 // #define IOCTL_WDT_SETTIMEOUT 0x1005 // #define IOCTL_WDT_REBOOT 0x1006 HANDLE m_hWDT=NULL; TCHAR szClassName[60]; // assign the WDT driver name wsprintf(szClassName, TEXT("WDT1:")); // Open the WDT driver m_hWDT = CreateFile(szClassName, GENERIC_READ GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if ( m_hWDT == INVALID_HANDLE_VALUE ) { DebugMsg(CString("WDT driver fail")); return; } DWORD dwTemp; DWORD nIndex=2; TPC-1070 User Manual 48 // Set the Watchdog Timer as 10 seconds.

This section describes the operation of the watchdog timer, and how to program it. The watchdog timer is built into the super I/O controller W83627HF. It provides the following functions for user programming: • Can be enabled and disabled by user's program. • Timer can be set from 1 to 255 seconds or 1 to 255 minutes. • Generates an interrupt or resets signal if the software fails to reset the timer after time-out. TPC-1070 User Manual 52 C.2 Watchdog Timer Programming The I/O port address of the watchdog timer is 2E(hex) and 2F(hex), 2E (hex) is the address port. 2F(hex) is the data port. You must first assign the address of register by writing address value into address port 2E(hex), then write/read data to/from the assigned register through data port 2F (hex). Figure C.1: Watchdog timer programming procedure 53 Chapter C Table C.1: Watchdog Timer Registers Address of register (2E) Attribute Description Read/Write Value (2F) and description 87 (hex) ----- Write this address to I/O address port 2E (hex) twice to unlock the W83627HF 07 (hex) write Write 08 (hex) to select register of watchdog timer. 30 (hex) write Write 01 (hex) to enable the function of the watchdog timer. Disabled is set as default. F5 (hex) write Set seconds or minutes as units for the timer. Write 0 to bit 3: set second as counting unit. [default] Write 1 to bit 3: set minute as counting unit F6 (hex) write 0: stop timer [default]01~FF (hex): The amount of the count, in seconds or minutes, depends on the value set in register F5 (hex). This number decides how long the watchdog timer waits for strobe before generating an interrupt or reset signal. Writing a new value to this register can reset the timer to count with the new value. F7 (hex) rd/wr Bit 6: Write 1 to enable keyboard to reset the timer, 0 to disable.[default] Bit 5: Write 1 to generate a timeout signal immediately and automatically return to 0. [default=0] Bit 4: Read status of watchdog timer, 1 means timer is "time out". AA (hex) ----- Write this address to I/O port 2E (hex) to lock the watchdog timer.2 TPC-1070 User Manual 54 C.3 Example Programs 1.
