Default IRQ settings...

I was messing around with the settings (when you press F2) yesterday, and now, I don't have any sound. Is it possible that changing the IRQ settings caused it? What are the default IRQ settings?

    Thanks, but I was messing around with the settings when you first turn the computer on, and press F2 during the boot process. There was a place where there are assigned IRQ numbers, and I know nothing about that and think I may have messed something up.

If you were just messing around with the keyboard, you have have just muted your audio output. You may even see in the lower right corner of your screen a red circle with a line through it over the volume control icon.
Laptop keyboards have function keys that let you mute your audio from the keyboard. Go into your control panel and click on the sounds icon, see if you have the mute box checked and uncheck it to un-mute your audio

10 reasons why PCs crash-You must know tip 3


3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

Things You Must Know To Avoid PC Crash Part 1



Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."
You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?
1 Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:
* Start-Settings-Control Panel-System-Device Manager.
Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.
Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.
Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).
When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.
To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.
2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.
One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.
Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.
EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

You have a n IRQ conflict meaning you have a device that is trying to use an IRQ slot that its not meant to talk on. From the looks of it you have been in the bios already so go back in and set it to factory default.

CAN YOU FREE UP COMPORTS 1 AND 3 OR 2 AND 4 FOR USE WITH OLDER PR


This is done in your BIOS. You need to enter the BIOS at boot time by pressing DEL or F2 or whatever it says during POST but before the operating system starts. Your question reflects a certain level of technical competence so I'll continue, with the advice that you can really mess things up tinkering in the BIOS. On the other hand most BIOSs include a useful "return to defaults" pick for just such occasions.

You need to reserve IRQ 4 for the COM 1/3 pair and/or IRQ 3 for the COM 2/4 pair without knowing which BIOS you have, I can't be more specific how this is accomplished. Your goal is to prevent the PCI bus allocator from stealing those IRQs. Obviously (?) you will need to verify that COM ports are enabled. This all presumes that your special sewing machine application wants to attach the COM port hardware and go around the operating system. At that level you'll need to fool with XP's DOS Compatibility mode settings. Assuming you have XP.

You might try reposting the question naming the operating system and the error or reason why you feel the need to "free up" the COM ports.
