    - Question about system page table entries Hi reading about terminal server sizing I recognized the term "system page table entries" quite often. Unfortunaltey I understand the 4 GB virtual memory is devided into 2 GB users space (a private space for each process) and a 2 GB system space. Page table entries are used to map virtual memory addresses to physical ones. From my understanding, system page table entries are used to map the complete 2 GB system space to physical memory and normal PTEs describe the users space. I heard SPTEs are a limited resource and the OS is not able to use the complete 2 GB space due to this limitation If I'm wrong and SPTEs describe only portions of the system space, which portions are described? Why isn't it possible to use just PTEs I appreciate your help Stephan Tag: Accessing floppy disks with 10 sectors per track Tag: 44391

    - How to Set default audio device? Hello to all, I need your help. I'm programming in VC++ and I need to change the default audio device in Windows98, 2000 and XP. I've found a function that returns the ID of the preferred audio device (waveoutmessage) but I need to change the preferred audio device. I don't know how to do that... may be It can be done through the registry... Thank you. Tag: Accessing floppy disks with 10 sectors per track Tag: 44385

    - question about using VC6 with DDK Hello, i just bought Walter Oney's book on WDM drivers. so far it is really good, but i am just at page 100. at this moment i have 2 question: - in the introduction Walter says that he uses VC6 for programming and building device drivers, but i havent found am explanation so far that tells me how to set this up. is it enough to just change the compiler? and what am i supposed to enter for build target?is it enough to use the VC6 plugin or do i need to do more? - is it possible to use VC .NET 2003 instead of VC6? i still use both on my system, but i would rather move to VC .NET where possible. i am sorry if i ask questions that are answered in the book, but i have skimmed through it to see if they were, and did not find anything. i have not read the book completely, but wanted to compile an empty example to get a feel for it. rather than taking a finished example from the CD, i would build an empty driver myself so that when it is finished, i would really know what was in there. kind regards, Bruno.

    - Bluetooth HCRP credit flow Hi Folks, I am developing an HCRP firmware (Printer side HCRP profile) and testing it against the XP Bluetooth HCRP driver. I am successfully able to - have the XP host detect my device as a "HCRP Printer", - the L2CAP Control and Data channels getting created - a new printer also gets added to my "Printers and Fax" collection on the HCRP Host. Now When I try and print a document using this HCRP printer following happens: a. I get a CR_DataChannelCreditRequest on the L2CAP COntrol Channel (Printer side) to which I reply with a large number of credits (0x00 00 00 00 00 FF FF FF). b. I start recieving bytes on the L2CAP Data channel. c. After recieving 64KBytes, the Host application doesnt send any more packets. Neither any bytes on Data Channel, nor any more CR_DataChannelCreditRequest. However I recv. all the data for if the print data is less than 64K, my question is this 64K any magic number ? IMO I should be getting periodic requests for credits on the Printer side after the HCRP Host has exhausted all the credits, but no such thing happens. How has the HCRP driver in XP been implemented to handle this situation ? I have also tried sending some credtis (voluntarily) from the printer side to the Host using the CR_DataChannelCreditGrant after the 64K bytes of credit have been exhausted, but to no avail. help in any direction appreciated. thanks people for all your patience.

    - Bypass print processor Hi I have a customized print processor associated to a printer. That print processor copies the Spool files of jobs printed by users. In another application, users will take actual print outs with those spool files using the same printer. When they are actually printing, I should bypass printprocessor (Otherwise, it again copies the spool files). How to write RAW data directly to Port monitor/Printer, bypassing the print processor In my application I tried like this StartDocPrinter() StartpagePrinter() Read the spool file() WritePrinter(); // Tried printer name, Port name. Both are spooling the data.1 loop until end of file EndPagePrinter() EndDocPrinter() In the above approach, printprocessor is getting invoked. Also I tried different spooler properties like Print directly to printer. That too didn't work Is there another approach all together(My client does not want 2nd printer associated to another print processor) Thanks & Regards Kira Tag: Accessing floppy disks with 10 sectors per track Tag: 44374

    - SetupCopyOEMInf stuck on oem0.inf Hey all, I'm using SetupCopyOEMInf to pre-install 2 different INFs. Both calls to SetupCopyOEMInf copy to oem0.inf. So basically the second copy overwrites the first. This did not used to happen and it does not happen on any other machines I've tested it on. This just started happening one day and it hasn't cured itself. Does anyone have any suggestions or ideas on what might be going on?

    - port monitor XcvDataPort(pszDataName="MonitorUI") Hi all The MSDN docu says that: If XcvDataPort of a port monitor is call with the data name L"MonitorUI", it should return the name of the user interface DLL (which should reside in %System32%). I use a GPD printer description with the microsoft UNIDRV.DLL and UNIDRVUI.DLL UNIDRVUI.DLL is listed in the dependent files of my printer. My monitor answers L"MonitorUI" with L"C:\\WinNT\\System32\\UNIDRVUI.DLL". When I try to configure a port in the "ports" section of a printer's properties dialog, I get a message box telling me that this action could not be finished. Any hints welcome.

    - PPC2003 802.11 Driver connection problem I have a driver for an 802.11 device that works on PocketPC2003 and I am trying to make it support windows 802.11 OIDs. Scanning works fine and Wireless properties panel displays all APs, and when I select one, OID_802_11_SSID comes to the driver correctly. I return NDIS_STATUS_PENDING, get the MAC to associate succesfully and in the assoc confirm indication I do NDisMSetInformationComplete, followed by NdisMIndicateStatus with NDIS_STATUS_MEDIA_CONNECT. OID_GEN_MEDIA_CONNECT_STATUS also shows connected state. But wireless properties does not show that I am connected to the AP. DHCP also does not happen. Why is this happening? Ndis goes on trying to associate with the other APs in the list, with the same result in each case. What else do I need to do to inform NDIS that the card is associated? I tried doing the connect indicate as soon as I get the set SSID request, to eliminate any timing problems, but there is no difference. My driver ndis version is 4.0 - when I tried building as 5.1 the driver did not load. Tag: Accessing floppy disks with 10 sectors per track Tag: 44290

Type Indicates whether to set a system or a device power state. Drivers must specify DevicePowerState. State Specifies the power state to be set. Drivers must specify an enumerator of DEVICE_POWER_STATE: PowerDeviceD0, PowerDeviceD1, PowerDeviceD2, or PowerDeviceD3. "Drivers must specify DevicePowerState",what does this sentence mean? it means the second parameter must be DevicePowerState or we have to set device power state to a value ,such as D3 ?

And I can get the array of object - MSNdis_80211_WlanBssid-.

As a result, the information what I got was very invalid. I could confirm the invalidity by CIM studio as well. Please let me know how to get the information of BSSID lists which structure were NDIS_802_11_BSSID_LIST_EX. I hope, I could get a bssid lists buffer which is a c style structure of NDIS_802_11_BSSID_LIST_EX. Thank you. Have a nice week.

How to write inf file for install upper filter driver ???. Can I add this to inf file used to install function driver. Tag: Accessing floppy disks with 10 sectors per track Tag: 44170

    - KeDelayExecutionThread I have a driver that must handshake bytes across an interface, and must poll a hardware register before sending each byte. I currently am using KeDelayExecutionThread() to delay so that hopefully the driver is not consuming all of the cpu cycles. Is this an acceptable technique? If so, should the WaitMode argument to KeDelayExecutionThread() be UserMode or KernelMode? The DDK recommends UserMode if the wait is a "long term wait". What constitutes a "long-term wait" ???? The DDK also says "Lower-level drivers should specify KernelMode". What does it mean by "lower-level driver? What is the minimal Interval (# of 100 nsec periods) I can specify in KeDelayExecutionThread() ? Tag: Accessing floppy disks with 10 sectors per track Tag: 44167

    - Filter driver for CD Read/Write activity Dear Sir, I want to know whether is it possible to monitor Read/Write activity of CD by writing a kind of filter driver? Like File system filter driver is there to monitor Read/Write of file activities.Similar thing i want to do for CD-ROM also. Plz reply. regds vinay Tag: Accessing floppy disks with 10 sectors per track Tag: 44164

    - Trouble installing driver from install program. Hi. I have a driver based off the fakemodem.sys example driver in the DDK. It installs ok from the modem control panel, however I need to do it with an install program because some registry entries need to be written that will be read later by the driver. I am basing my install program off Walter Oneys FastInst and have a problem at the UpdateDriverForPlugAndPlayDevices step. GetLastError returns E000022D which is ERROR_NON_WINDOWS_NT_DRIVER. If I skip that step, I can reboot and I get a dialog asking me to show it the driver, if I do then I get the error "This driver does not support Windows XP". This is wrong because it (the .sys) was compiled with the XP DDK. If I look in the setupap.log file it has that error message for both cases, using the UpdateDriverForPlugAndPlayDevices function and the reboot, dialog box method. In setupapi.log it say, this driver does not support windows xp. It is not even looking at the .sys however, there must be something in my .inf file preventing windows from installing my driver. Any ideas? The same .inf file works fine when installing from the Add Modem control panel option. I am a MSDN Universal customer if this helps.

Hi,

I've got some old double-sided double density disks that are formatted with
10 sectors/track rather than the standard 9.

Do anyone have any ideas how I could read/write these under 2000/XP?

I noticed from looking at the DDK that flpydisk.sys doesn't support this
layout. I was wondering whether it's possible to write some sort of simple
filter driver to tell it about the extra sector per track?

Just in case this is important, sector ids run 1 through 10, track numbers
(in the sector headers) run 0-79 on side 0 and 128-207 on side 1.

Actually, it would be really handy if I could get at the actual sector
headers as well as the data...

Regards,

Jonathan Needle
