I have 4 slots and the 4 sticks of memory are paired (TWIN...)Is this a correct placement: 1GB-512MB-1GB-512MB? I have read on another forum that I should make some changes in BIOS for the best performance. Is this true?

You need to read your mobos documentation. The various brands don't have a consistent layout or color coding scheme. You want a 1G and a 512MB on each channel, and both 1Gs in the same place in it eg both in the first or both in the second slot for the channel.
The BIOS probably be set to use official spec timings, which are potentially looser than your ram is rated at. YOu can change your board to match, but the gains from timing changes are very small and naming and layout are again cryptic and inconsistent between brands so you'll need to read your docs.
If you're messing with settings the one that you probably can't leave at dimm specs is that with 2 dimms per channel you almost always need to use 2T instead of 1T, the bios should've done this for you though.

The motherboards slots are colored in 2 colors (blue-blue-black-black), so probably the example that you suggested (1GB-1GB-512MB-512MB) is the correct one.

read your manual, it's the only way you can be sure. I've had boards where slot1 of channel A and slot1 of channel B had one color, and the slot2's had a second. I've had boards where both slots of channel A had one color, and both slots of channel 2 the second. I've had boards where the ordering was CA-S1 CB-S1 CA-S2 CB-S2, and boards that were CA-S1 CA-S2 CB-S1 CB-S2. The color coding is useless across brands.
That said, assuming your machine was originally put together correctly the 512's are in the first slot of each channel and you can just stick the 1G's into the two open slots.

I do the same thing in PPC .
but now I want to boot my pc into Linux because of interesting.
Is any one can interact with me.

What is BSP ?
What is PPC ? ( is it a PowerPC processor ? or something else? )

yes, it's Powerpc CPU

They worked fine during the first year, but shortly after the 1-year warranty expired, they stopped working. I've updated Windows XP and the Conexant audio driver but still no sound. How can I determine if it is a hardware or a software problem?
Thanks.

Well you could try plugginig in a pair of headphones, if it then starts working then its probably a hardware problem. To find out if its windows then you could start up a linux live on CD like ubuntu or knoppix etc, play some sound in that, if that works then you know windows is your problem...

But what if the new laptop has no internal speakers?

I am working on a Silicon Labroratories F340, and in my KEIL uVision3 I
have found it in the "device database". I can make a project with this
chip set. But when I compile the project, it showed error message "path
for toolset undefined".
I checked the tools.ini, it only contains my email address.
Thanks.

I have an annoying problem with my Windows Advanced Server 2000 locking up - no keyboard or mouse input.
I am now running standard PS2 mouse "in parallel" with my wireless mouse and when it locks up neither mouse will move the cursor.
The only way to recover is to turn the power off which creates havoc with my RAID!
Is it possible that the battery in MS keyboard / mouse is getting weak and causing this?
I have replaced battery in keyboard - and it seems to "solve " the problem.
Anybody else with similar experience?

receive a interrupt for a device -> tell the cpu that there is a interrupt ->
the cpu ask 8259 the interrupt number -> 8259 tells it
I don't think it's necessary to divide it into 2 parts, 8259 could tell the interrrupt number directly. I doubt whether it is the original design goal.
Any explain? Thanks.

Hi,
a lot of peripherals work this way; they basically connect to the CPU using an address bus,
a data bus and one interrupt line (plus maybe a clock, a read, a write, a chip select).
The address and data bus (and control lines) are shared, the interrupt line is individual.
When they want the attention of the CPU they signal an interrupt; then the CPU, when it
chooses to do so, interrogates the chip to find out the exact cause for the interrupt.
Such peripherals are slave devices, they cannot grab the address and/or data bus,
they can only request the CPU's attention. It is the same for simple parallel port adapters,
for simple serial ports, etc.
The address and/or data bus (and the control lines: read, write, ...) is "owned" by the
bus master, which is either the CPU or some other rather comples device (typically
with DMA capabilities, such as a disk controller, a network controller, ...).

I see it. Thanks.
I think if the interrupt pin can carry interrupt no. infomation, it'll be much more efficient.

Sorry to state the obvious but ....
It's a pin - it can only be on or off. It is physically impossible to show more information than active or inactive

No, it is not physically impossible to transmit data over 1 pin (+gnd, obviously). The interrupt line just never was designed to carry more information. (It would, however, be one-way only and require some synching via alternating the line first).
Cheers,
Sebastian

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.
Cheers,
Sebastian

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
