IRQ's, DMA's, and Memory Addresses: How to avoid conflicts and make things work. Millions of you use HP laptops or desktop PCs and almost all of you have encountered problems about hardware devices. Examples are that there is no sound from your HP. HP DeskJet 1010 Printer is very easy to connect with your computer and easy to operate printer. That leaves only 1. For this reason, a good understanding of what IRQ's are. With. today's architecture and the introduction of PCI and PCI- Express, IRQs. The table below is a general outline for standard. IRQ assignments. IRQDEVICE. USED in AT, 3. 86, 4. Pentium Computers. System. Controller. Tied. to IRQs 8- 1. COM. or Sound Card. Floppy. Diskette Controller. LPT. Time Clock. 9Substitutes. Mouse Port. 13. NPU. Numerical Processing Unit)1. Primary. Hard Disk Controller. Secondary. Hard Disk Controller. Depending on the computer's configuration, add- in devices such as SCSI. The most common IRQ conflicts seem to be between two COM ports. The table below explains each IRQ and. IRQDevices used and potential. IRQ is used within the system board for system timing. If a conflict. arises with this IRQ chances are the system board is bad, use a. This. IRQ is assigned to the keyboard. Its never available to other add- in. Again if this is the problem, its most likely a problem with the. This. IRQ was assigned to older EGA video cards. Beware, IRQ 9 uses IRQ to. CPU, therefore this IRQ should only be used under. This. IRQ is assigned to the serial ports: COM 2, and COM 4. Avoid setting. other devices to this IRQ since mice, modems, and other devices are set. IRQ. 4. This. IRQ is assigned to the serial ports: COM 1, and COM 3. Remember IRQ. lines for the most part cannot be shared, so generally you can't have. COM 1 and COM 3 that are both active and working. This. IRQ is assigned to a secondary printer port LPT2, but in the absence of. IRQ for the COM ports. This. IRQ is assigned to the diskette controller. Few if any devices leave. IRQ as an option, since most systems have a floppy drive built. This. IRQ is assigned to the first parallel port LPT1, its also made. This. IRQ is reserved for the internal real- time clock. This line is never. If there is a conflict here, its an. This. IRQ uses IRQ 2 to talk to the CPU, so it has a high priority. Its. generally used for network cards. This. IRQ is left open for network cards, sound cards, SCSI host adapters. This. IRQ is a common one for SCSI host adapters, but can also be used for a. This. IRQ is used for the PS/2 style mouse port included on many. If the PS/2 mouse port is enabled in the system's setup. PS/2 connection mouse, don't use this port. This. IRQ is reserved for the Numeric Processing Unit (math coprocessor) It. This. IRQ is assigned to the primary hard drive interface. This. IRQ is assigned to the secondary hard drive interface. DMA Channels. Plug and Play systems may make their own choices about many DMA. Under Windows 9. 5, the only place to make Pn. P resource. assignments many be under the specific device's Resource tab within. Device Manager in the System Properties of the Control Panel. The table. below shows the most common settings for Direct Memory Access (DMA). DMA Channel. Devices commonly assigned. Assigned. internal to the system board, you shouldn't be able to use it. No. specific assignment, although its usually used for sound cards, or SCSI. Assigned. to the diskette drives. No. specific assignment, although its again a common choice for sound. SCSI host adapters. No. specific assignment. No. specific assignment, however Sound Blaster- type cards generally use. DMA channel. 6No. No. specific assignment. I/O Addresses. Within the computer's memory map, certain memory addresses are. Listed below you will see the common. I/O addresses with problems, and what hardware should be assigned to. These addresses are in hexadecimal format. I/O Address. Common Device using Address. Used for SCSI host adapters. Used for SCSI host adapters. Secondary IDE Interface. F0h. Primary IDE Interface. Typically used for Sound Blaster- type sound. An alternate address for sound cards. Assigned to LPT2 or LPT3 and generally used. IRQ 5. 28. 0h. Network Interface cards or the Aria Synthesizer. A0h.
