I want to know " what are the parameters passed when a message is passed from one system to another conneted over LAN"?
Please can any one list the parameters by which another system is detected in LAN.
Thanks in adv...

actually I am not aware, in which forum I should post this question. Thts why I posted this question in more than 1 forum.

For future reference take your best guess and only post in a second location if after a day or two you get no responses. Explicitly state why you posted a second time and edit the original to link include a link to the second.

Depends on the physical network, the protocol, and the message.

What is the Best solution to get IP Adress of a Router when you have more then two three Routers in same place to go in its Settings.
I am not a network guy but i am posting this question on behalf of a friend who is new in this field and has to give Network support.

Try making sense, then you might get an answer.
Tracert is usefull if you want to know the router hops from one endpoint to another. If thats what you meant.

Hello, I am beginning to programme in assembly on intel x86 processor, but I would like to learn input and output. I have been reading some articles and tutorials which say that input and output in assembly programming is complex and so there is the need to sought for some written input and output routines. Is there any tutorial or articles available that treat input and output that I can learn, or if a book that treats it that I can buy? I would like to understand how it really works. Thanks.

What do you mean by Input/Output? Do you mean IO such as keyboard, screen etc? Or are you thinking of more complex things?

When I need or want to implement some algorithm in assembly code, I'll make sure to take advantage of a higher-level language for input/output and/or GUI. IMO doing those in assembly too isn't worth the trouble.

Hey Everybody
What is the difference (if there is one) between a .DRV driver (like winspool.drv) and other drivers with .sys extension?
Thank you!
|
|

Hi,
Technically there are not many differences because its a portable executable[^] just like other types of windows-loadable object code. If your wondering why it has the 'DRV' extension it is because it is a usermode driver. In other words if you check the subsystem member of the IMAGE_OPTIONAL_HEADER in the PE file...most DRV files will have WINDOWS_GUI==2 while most drivers with a SYS extension will have NATIVE==1.
But there is nothing stopping a wisecrack software engineer from naming his dynamic-link library with a .WTF extention. In other words... the extensions do not really mean much at all.
Best Wishes,

Thanks, it explains many things!

Yeah, as Randor says, a sys is subsystem native. Its also got to have a check sum, and its entry point is Driverentry.
Conecptually a (sys file) driver has no main function. After loading its driventry can be paged out, its no longer needed. All it does during initialisation os to register funcitons with the OS to handle various events.
So it might create and register an objetc that user mode can access (dos device name, such as 'COM1'). It might register an interrupt handler as well for example.
A drivers job is to 'bridge' parts of the OS, and is totally under the OSs control.
A driver can also not create any GUI components.
And, a driver is also about 100 times more complex than the worst application to write. For example, you cant touch paged out code or data when running at elevated levels (think during interrupt processing, althouhg there are more common other high levels not related to interrups).

Hi.
Which model of modem support ATC0 command? ATC0 is an ATCommand that turn transmitter off.
Many of modems don't support it.
Thanks.

How is anyone supposed to know that without testing each and every modem on the market, including cell phones?

I recently acquired one[^], however, one of the chips seems to have burnt out/exploded, it's only a small 8 pin one, and by the looks of it's position on the board it has something to do with power regulation. Unfortunately, pretty much all the identification has been burnt off the chip, and I have been unable to find any information about the chip, so I was hoping someone who may own one of these motherboards would be willing to take a look at theirs and find out what the chip has printed on it? Here is a picture of one of these boards, I have circled the chip in question: Click
Thank you, it will be greatly appreciated!

I don't have one, I do have a few comments:
1.
it definitely looks like an 8-pin surface mount device. And I can't help it, but from your image, it looks to me like a quad DIL switch, i.e. a block of four little on/off switches, not a micro-electronic part. So I suggest you look for a User's Manual, which would (a) probably contain more information in general, and (b) explain the switch settings assuming it is a switch. OTOH I can't imagine what kind of option would be set through switches that involves a current sufficient to blow it to pieces.
2.
if one blows a component beyond recognition, it is likely the board itself (in particular some of the tiny traces on inner layers, invisible to the observer) is also damaged beyond repair.
3.
do you know what has happened? what caused it?
4.
you might want to also publish one or more actual pictures, in its current state.

I managed to get a copy from the Via website, unfortunately, it makes no reference to the chip

That is what I was thinking, but I would still like to have a go at repairing it

Unfortunately no, it was sold to me as "working"

Well, the board looks the same as it does on the picture, the chip just has a small blackened hole on its surface.
Thanks for the reply

Other than confirm it is most likely part of the power supply/monitoring circuitry, I'm afraid I can't help you further.
PS: You not only need the part ID, and a spare part, you also need to figure out its orientation. The time that all chips had the same orientation are probably long gone.

The power supply definitely works, I tried it on other motherboards.

True, and there does not appear to be a notch on it either to indicate its orientation. However, there is what looks like a letter still remaining on its surface, so that could be used to figure out the orientation of a replacement
Thank you for replying

That is normal; you'll have a hard time damaging the PSU, other than blowing a fuse. Nevertheless, the circuitry near the power connector will create additional voltage levels for some peripherals, and monitor everything on-board.
Lloyd Atkinson wrote: like a letter ... could be used to figure out the orientation
Bonus points for optimism. Different manufacturers of equivalent parts may try and confuse you! I'd rather go with a voltage-limited ohm-meter and the chip's data sheet to figure out orientation if board documentation nor white print help out.

I agree that it's probably part of the MoBo's power regulator. You could replace the chip, if you ever find out what it is, but the bigger question is what caused it to explode in the first place? Just replacing that chip probably isn't going to fix the problem.

Hi Lloyd,
That is the mosfet driver transistor. I am not positive... but its probably this one:
