How to get value from this register...
Hi guys,
I have trouble in understanding how to ge the value of the following
register:
Here is the pdf doc:
http://www.winbond.com/e-winbondhtm/partner/PDFresult.asp?Pname=182
On page 27 there is the structure of the registers.
I'd like to get the value from Bank1 (reading temperature) for example.
I guess one needs to use the index register 295h to activate read from
Bank1 through 296h.
It's not really clear what I need to write to 295h to be able to get
value of Bank1 through 296h.
Can anyone enlighten me?
My Professor at school wasn't sure either, he just raised his armpits :-)
I'd really appriciate any answer.
I'm currently trying to elevate the knowledge I gained at
microcontroller programming classes to PC hardware ;-)
Thanks, Richard Tag: Layered Service Provider on Pocket PC Tag: 47562
Question about modifing the NDIS packet?
Hi everyone,
I am trying to modify the NDIS packet. Do i need to allocate new buffers?
I want to modify the destination IP address. I am doing the address mapping,
if i receive data for specific destination, i want to redirect that data to
go to another IP address. Do i need to allocate new buffers, copy all the
data from old packet, modify it and then send it again. Can i do the
following?
1. Query the NDIS packet.
2. Get the Virtual Address.
3. Modify the Header, with new IP and checksum.
4. Allocate new packet from my own pool.
5. Copy all the header information and OOB data.
6. Send that packet again.
Can i use the same buffer and packet. Or i will have to allocate new buffer
and packet if i am modifing the data in the packet.
Thanks in Advance

Adding a Driver that's a part of 2000/XP
Good day,
I'm trying to automate the installation of a custom print monitor that
will just use the "Generic / Text Only" driver that is included by
default with Windows and then bind my custom port monitor to that.
I've done enough research to figure out that I could do something
like
AddPort
AddMonitor
AddPrinterDriverEx
AddPrinter
and it seems it will work as long as the right files are copied in
place prior to the install and I perform the correct enumerations to
watch out for duplicates first.
My problem is at the AddPrinterDriverEx step:
Since the driver I want to use is a part of the default windows 2000
and XP install, how can I trigger the functionality that would look in
the drivers.cab and pull out the correct driver if it's not already
installed? Is there an API to access this?
Thanks,
Chris

DefineDosDevice seems never works in C#

static extern int DefineDosDevice( int dwFlags, string lpDeviceName, string

AttachedDevice vs. AttachedToDeviceObject
In the sfilter sample of the IFS there is an element of the device extension that the filter creates called AttachedToDeviceObject. Inside the DeviceObject structure there is a guy call AttachedDevice. Both are PDEVICE_OBJECT.
Now why does the sfilter sample need AttachedToDeviceObject if the other already has been defined? Clearly there is a difference because I'm running into a situation where I rely on AttachedToDeviceObject to call to IoCreateFileSpecifyDeviceObjectHint , and therefore avoid getting called back on my own call.
But I find that after I make this call , which appears to return successfully, I cannot use IoCreateFile without things breaking up. In the case where they do break up , I find that AttachedDevice element of the DeviceObject in question is 0, yet the AttachedToDeviceObject appears valid.
What exactly are the semantics of these elements?
Any thoughts?

IDE interrupt wih windows 2000 SP4
We have an IDE cdrom that has the IDE interrupt disabled by default. It seems that Windows 2000 prior to Service Pack never enables the IDE interrupt by writting to the Device Control Register but yet the drivers are interrupt driven.
It seem Microsoft has recognized this problem and fixed it in SP4 since SP4 does enable the interrupt before doing enything else.

Ne2000-compatible driver
Hi,
I am developing BSP for MIPS based platform. I need to enable CETK which in
turn demands a fully functional Ethernet port. For this purpose I need to
bring up my on-board Ethernet port which is neither PCI based nor ISA based.
It is mapped through IO controller.
I added Ne2000-compatible driver from drivers->Networking->LAN devices from
Catalog and set the environment variable 'BSP_ICS' in my platform settings.
Since the registry entries corresponding to this driver have been added in
platform.reg, I expected the driver to be loaded at boot-up. But I am not
able to see any debug string on console which were given in
Ne2000Initialize() function of the driver nor am I able to see the
corresponding dll loaded among system modules loaded.
There are couple of doubts I have:
1.. Is there something else to be done which I am missing? Some registry
entries or environment variables?
2.. Since this Ne2000-compatible is PCI based and my Ethernet port is not
a PCI-based one, is it that it does not load the driver at all because of
this reason? Tag: Layered Service Provider on Pocket PC Tag: 47532

Out of order packets from NDIS IM
Hi All,
DDK says:
MiniportSendPackets receives an array of packet descriptors arranged
in an order determined by the caller of NdisSendPackets. In __most
cases__, the intermediate driver should maintain this ordering as it
passes an incoming array of packets on to the underlying miniport
driver. An intermediate driver that modifies per-packet information or
OOB data in incoming packets before passing them on to the underlying
driver might reorder an incoming array.
Now what is this "most cases". Is it the case when "intermediate
driver that modifies per-packet information or OOB data in incoming
packets", or any IM driver (i.e. one not modifying the packets) ?
In IM driver, in MiniportSendPackets routine I am cloning the packets
(only TCP/UDP packets) and sending them after some processing. I may
have to send the packets out of order due to the processing needs.
Will everything work fine ? (I was thinking it must work fine, since
IP (on which TCP/UDP rides) is capable of receiving packets out of
order.)
Any comments will be appreciated.
TIA

I'm building cosumized dll using unidrv model (oemdll

I used SetPrinterData and GetPrinterData in the UI dll it
worked fine, GetPrinterData also worked fine in the
customizaion dll of the graphics engine.
I'm faceing a problem I tried to use SetPrinterData, or
EngSetPrinterData, both return code 5, i guess this means
access violation.
the code is:
dwResult = SetPrinterData(pdev->hPrinter,
STDSTR_FONTDATASIZE,
REG_DWORD,
(PBYTE) &FontSize,
sizeof(DWORD));
where FontSize is a DWORD and STDSTR_FONTDATASIZE is
defined as follows:
#define STDSTR_FONTDATASIZE TEXT("FontDataSize")
hPrinter is stored when the driver received the EnablePDEV
call, and it worked in GetPrinterData.

1394 Async Write STATUS_IO_TIMEOUT
Hi,
I have to perform an async write to an IEEE 1394 bus device. The device 'stalls' the response until
it completes the operation which is triggered by the write request. Currently this takes aprox. 270
ms. But it seems that the 1394 bus driver stack of W2k Prof. SP4 completes the transaction prior by
returning STATUS_IO_TIMEOUT. (After approx. 200ms.) Under WXp SP1 I could not observe this behavior
so far.
Are the corresponding timeout values defined in the IEEE 1394 bus spec.?
Is there a facility to tweak the applied timeout value at the 1394 bus driver stack?
Any hints are appreciated.

Print driver: Removing PaperSize definitions
Hi,
I noticed a problem with the size of a vendor specified paper size in my Unidriver GPD file. I fixed it, but it appears that the old definition still exists. I did a search on my XP registry and found the old name under several entries, one being HKLM\SYSTEM\CurrentControlSet\Control\Print\Forms. I think this is causing me problems because the only way to get the fixed version to appear in the driver "properties" section is to give it a different name.

ImageProcessing and banding...
Hello all;
(Win2K UNIDRV OEMDLL)
I'm doing a custom halftone (downconversion from 8BPP to 1BPP) in ImageProcessing, and handing the bitmap back to UNIDRV for output to spooler. With a res of (203(X) x 508(Y)), when a page is rendered in 2 bands (i.e., a 1728 wide x 5588 Letter size page), the data output is 2 x the height of the first band, NOT the sum of band heights.
That is:
(from pBitmapInfoHeader->biHeight)
Band 1: 2800 lines high
Band 2: 2788 lines high.
Data out = 5600 lines, NOT 5588. Obviously, the last 12 lines are garbage data.
I'm processing the data and returning it in the supplied bitmap area, and returning
*ppbResult = pSrcBitmap;
for each band.
Should I handle banded (repeated) calls to ImageProcessing
*differently* from single-band page calls?
If all else fails, I can write to the spooler directly, but I'd rather not.
Thanks!

writing and reading from several I/O addresses. As I know in windows, I
can not access low level I/O directly.

it. If you could give me some information on how to write device driver, I

SATA disk drives - IOCTL_ATA_PASS_THROUGH support
I've been looking for a third party SATA controller that supports
IOCTL_ATA_PASS_THROUGH, but I've had no luck. Does anyone know of a
controller that supports this?
From what I've seen, third party SATA controllers (Adaptec, Promise)
are implementing there miniport drivers as SCSI miniport drivers, so
IOCTL_SCSI_PASS_THROUGH is supported, but not IOCTL_ATA_PASS_THROUGH.
This makes something as simple as sending an Identify command through
the pass through interface impossible (?).
Also, does anyone know if the Intel ICH5 chipset supports the
IOCTL_ATA_PASS_THROUGH for SATA devices?
Any feedback would be greatly appreciated.

Device to be opened from a DOS program (i.e., NTVDM)
Hello,
currently, I'm trying to modify a driver to be able to be opened from a
legacy DOS program (compiled with Turbo Pascal, if this matters).
Anyway, I can't find a way to do it.
There is a Symbolic Link created, and opening it from a Win32
application works like a charm.
Anyway, if the DOS based program opens the device (with a call to
LongOpenFile('\\.\giveio', F, fmReadOnly)), the call always fails.
Anyway, I can see from the debugger that the device is opened and
immediately closed.
And: Yes, I always return STATUS_SUCESS in response to IRP_MJ_CREATE:
Irp->IoStatus.Information = 0;
Irp->IoStatus.Status = STATUS_SUCCESS;
IoCompleteRequest(Irp, IO_NO_INCREMENT);
return STATUS_SUCCESS;
There is no other return path. I don't have a clue what to do. I thought
that the symbolic link might need to be created somewhere else than in
\DosDevices\, but since the IRP_MJ_CREATE routine is called (as well as
the IRP_MJ_CLOSE routine), I don't know where to search.
I already had a look at how LPTx are created, as they are accessible to
NTVDM programs, too, but I could not find a hint what I am doing wrong.
Any ideas?
Regards,
Spiro.

Point And print printing, cross platform problem
Hello,
I have tried following combinations:-
Note:- server is the machine were a printer has been shared. Client is a
machine which connects to the printer share.
1) windows 2000 client and windows 2000 server
2) windows XP client and windows XP server
3) windows 2003 client and windows 2003 server.
All the above cases works fine.GetPrinter(...) returns a non-NULL DEVMODE in
PRINTER_INFO_2 on the client and is the expected outcome
But if I am to mix like below:-
windows 2000 server and windows XP client
when I call GetPrinter(...) on the client machine. the pDevMode becomes
NULL, I feel I am missing something in my printer driver.
What could be the reason?
thanks

Has anybody been able to get the sample LSP that comes with platform builder
to work on Pocket PC? I could use some hints if anybody has succeeded.
