I agree. However, my statement was that the pin can only be active or inactive which is true. Your solution requires the addition of either an implicit timing element or an explicit additional line for synchronization to toggle the line in a meaningful way. I've seen both in proprietary buses. I got the impression from the OP's post that he wanted "the interrupt pin to carry the interrupt number" instead of just signalling an interrupt occured. I was pointing out that the interrupt "section" of the bus is only a single pin as compared to the data "section" which is a set of pins.

Ah, misunderstood you.
Sorry, I am not a native speaker of English. Please, bear with me 
And of course, signalling an interrupt number does not make sense. Reading it would take way too long to keep the line useful.

Hi all,
I have a P4 System . I have a problem of Date and Time of my System, when I save
the Date and Time in Bios it saved , But After a restart ,it come back in his previous state .
I've tried resetting the CMOS using the jumper on the motherboard, and I
replaced the Bios battery . But it still won't save the changes .
Plz sugess me If have you any Idea .
Thanks alot for this .

Was the battery "socketed" or soldered? If you just removed one and inserted another one, check the contacts/wiring.
Otherwise: Do you have a "fallback"-BIOS? If so, make sure it is not active - these sometimes are not backed up with a battery.
Cheers,
Sebastian

I want to develop an application which will use a cash-dispenser to distribute money for the labour on basis for how many days they have worked at the company  . i need to know abt the cash-dispensers, can u connect it to my pc? will i programe it myself? any price information (i need the cheapest 1). and any extra help/information ll b appritiated!!!
thanx in advance

Try Wincor-Nixdorf or any local banking hardware provider. You will probably need a system capable of dispensing coins AND paper, so the "cheapest one" won't do.
They usually offer a SDK which reduces the work in your software to a few simple steps.
If I was you, I'd go with automated cheque printing or wire transfer, though... it is easier to be sure that the right amount was printed than being sure the right amount was COUNTED.
Cheers,
Sebastian

Actually i want my application to give money to the labour right on the spot as our labour is 99% un-educated and dont have any back accounts etc... that y i need a dispenser to give then money to avoid large-queues to give them money by hand!!! and thats what the core problem and core-requiremnt of my application to satisfy!!! any help plzzz

Yeah, but you need to buy a dispenser first. And if you have, give the model number, so people know what hardware you are talking about. They are all different. As I said, Wincor-Nixdorf builds he kind of hardware you are looking for (ATM, etc.)
As for the requirements:
You know, the first thing they will do (even before making room for the next person in the queue) is counting their money. They will not trust the system, because they cannot watch the system count (closed flaps and high speed).
Also, I see your problem now: They labour won't trust cheques and wire-transfer. I missed that part somehow, mainly because employers only need to offer wire-transfer here in Germany. Everything else is optional - and the Employer might even choose to charge for other modes of payment.
Hmm...
Interesting problem. Let me think about it some more....
Cheers,
Sebastian

excuse for my english........i am from mexico
CAN I obtain the characteristics of my PC by means of assembly language?
and....give me the code please !!!!!!!!!!
can i help me??? Thanks !!!

Hi,
a lot of the PC characteristics (amount of RAM, disk size, USB devices, ...)
can be obtained WITHOUT assembly, assembly code does not help here at all.
some of the CPU characteristics (cache sizes, supported instructions, ...) can be
obtained with assembly, in particular by executing the CPUID instruction.
Intel offers an entire Application Note on that. Google it!
In order to run the CPUID from .NET, you would need a C/C++ native code DLL, and do
some PInvoke.

Hi guys,
I had it with this laptop, I have no clue why this Compaq Presario V3000 w/WinXP Home SP2 won't recognize the CD/DVD drive. 
I looked at the BIOS, and it doesn't show up there.
I looked at the Device Manager, and it doesn't show up there. (Yes, I scanned for new hardware too...)
At least, the Disk Management will sometimes list it, but not this time.
So, I am open for ideas. What do you suggest to do?
BTW, the CD/DVD drive works, so if I put a CD or DVD the disk spins, and the light flashes and all...but WinXP won't show anything.
Any help is appreciated.
Thanks,
...neualex

Sounds like the connection is loose or the drive hardware is on the way out. Many many problems are blamed on the software, but it can't do anything if the hardware doesn't respond to the messages sent.
Get it repaired/replaced.

Worst thing is that this drive is not removable, so I cannot check the IDE connection

All storage devices are removable. Your choice is to send it back to Compaq for repair or do it yourself (and void your warranty).

John,
Yes, I agree. All drives are removable; however, what I meant was this drive cannot be removed without actually opening the laptop.
I'd love to send it to Compaq, but warranty expired already for it.

See what happens if you try booting off a live linux CD. IF you have trouble doing this consistently it's probably a hardware issue, if it works flawlessly every time it's probably software.

I tried to boot it up from a live Ubuntu CD (I changed the BIOS), and it didn't do it.
So, I guess the drive is broken 
Thanks for your help.

- Hi! I just noticed this the other day, but in bios I have one temp sensor and it reads a minimum of 60C/~145F
- How do I recalibrate this because this just doesn't seem possible (fry an egg;P in there even though its cold ?)

I've never seen a motherboard that has the ability to recalibrate the sensors. It would appear that it has failed.

Check for bios upgrades for the motherboard.
I've had one or two MBs, where the bios code for reading the sensor was wrong, and was fixed in a later version of the bios.

I bought a thrift store Compaq Presario to use its power supply and case for a project.
It has a power switch on the back, but the front power switch attaches to the motherboard (which is now in the trash).
I need the power to be controlled only by the switch on the back.
After looking at AT power supply pin diagrams and experimenting I determined that connecting the PowerGood (Orange) line to the -5v (Grey) line does the trick.
Does anyone have any tips or gotchas to share?

Hi PIEBALD,
PIEBALDconsult wrote: connecting the PowerGood (Orange) line to the -5v (Grey) line does the trick.
that does not sound right at all, in many ways.
According to some documents (Google!) the "power good" signal is an output from the
power supply, which becomes high to tell the motherboard power is good enough to start up
(hence release the /RESET input).
If the control line is a pseudo-digital one, it should either be pulled high, or pulled
to ground, never negative.
Normally I expect you need to connect a SENSE input to the corresponding voltage output
(that is 3.3V SENSE to 3.3V; or 5.0V SENSE to 5V on older systems). The sense feedback
should occur on the motherboard, as close to the highest load as possible, it is intended
to achieve a well regulated voltage at that location, independent of voltage drops along
the cables/PCB tracks due to varying currents.
In conclusion, maybe you interconnected the right pins, but I doubt the names you
mentioned apply; and anyhow, if one of them is a sense line, the connection should be
next to the actual load, not right at the power supply.
So I suggest you check the documentation again, and possibly throw a multimeter to it,
to make sure voltages are what they should be.

Hi,
the fourth link tells us ATpsu should work without any special wiring.
didn't it work for you with PG open?
the second link suggests "power good" is an output which goes high when everything
has stabilized, as I expected. So connecting it to -5V seems a bad idea.
And I trust you read about the minimum load required (around 0.8A).

Most sources say that the AT PSU has the front switch connected directly to it, whereas the ATX has the front switch connected to the motherboard; this particular one seems to be an in-between design; newer than AT, older than ATX.
I'll mention that it also has another connector for the motherboard with three green and three black wires, which (from what I read) seems to be for PCI cards?

I skipped it until I read your earlier response.
