What else can I help you with?
What IRQ does LPT1 usually use?
LTP1 should use IRQ7.
Which two IRQ settings are connected together?
IRQ Ports 2 & 9 -Taylor
What IRQ does COM2 use?
COM2 typically uses IRQ 3. The Interrupt Request (IRQ) is a signal used by hardware devices to get the attention of the CPU. In the case of COM2, which is a communication port, it uses IRQ 3 to communicate with the CPU for data transmission and reception.
What system resources does com1 use com2 com2 com3 com4?
COM1-IRQ 4, memory addresses 03F8-03FF COM2-IRQ 3, memory addresses 02F8-02FF COM3-IRQ 4, memory addresses 03E8-03EF COM4-IRQ 3, memory addresses 02E8-02EF pg. 396
What IRQ does the system timer use?
0
What is the Interrupt Request IRQ assigned to LPT1?
By default IRQ 7 is assigned to LPT1.
Which port names and resources are assigned to most PCs?
COM1 is assigned 3F8h and uses IRQ Channel 4, COM2 is assigned 2F8h and uses IRQ Channel 3, COM3 is assigned 3E8h and uses IRQ Channel 4
Which IRQ does the hard disk controller commonly us?
6
Which IRQ does the FDD commonly use?
The floppy disk drive (FDD) commonly uses IRQ 6. This interrupt request line is designated for the floppy controller, allowing the CPU to manage data transfer between the floppy disk and the system. It's important to ensure that no other devices are using IRQ 6 to avoid conflicts.
What is the IRQ for the floppy disk drive controller?
By default, the IRQ for the floppy disk controller is IRQ 6.
What is irq3 used for?
IRQ Interrupt Request 3 are usually reserved for COM port (1,2,3,4) but can be assigned to anything.Interrupts are a commonly used technique for computer multitasking, especially in real-time computing. Such a system is said to be interrupt-driven.An act of interrupting is referred to as an interrupt request (IRQ
Which tab in the properties of a hardware device would be used to determine the IRQ assigned to the device?
Resource
When is an IRQ assigned to a device or controller?
The CPU has its own internal bus for communication the internal cache
List interrupts used with the IBM PC type sytems?
IRQ 0 - System timer. IRQ 1 - Keyboard. IRQ 2 - Cascaded signals from IRQs 8-15. IRQ 3 - COM2 (Default) and COM4 (User) serial ports IRQ 4 - COM1 (Default) and COM3 (User) serial ports IRQ 5 - LPT2 Parallel Port 2 or sound card IRQ 6 - Floppy disk controller IRQ 7 - LPT1 Parallel Port 1 or sound card (8-bit Sound Blaster and compatibles) IRQ 8 - Real time clock IRQ 9 - Free / Open interrupt / Available / SCSI. Any devices configured to use IRQ 2 will actually be using IRQ 9. IRQ 10 - Free IRQ 11 - Free IRQ 12 - PS/2 connector Mouse. IRQ 13 - ISA / Math Co-Processor IRQ 14 - Primary IDE. If no Primary IDE this can be changed IRQ 15 - Secondary IDE These are just a set of standard IRQs. For much more detail check our Ralf Brown's list located at http://www.cs.cmu.edu/~ralf/files.html
What is the command used to check IRQ?
To check IRQ (Interrupt Request) settings in a Linux system, you can use the command cat /proc/interrupts. This command displays a list of all interrupts, their corresponding IRQ numbers, and the associated devices using those interrupts. For a more detailed view, you can also use lspci -vv to see which devices are assigned specific IRQs.
What IRQ does LPT1 usually use?
LTP1 should use IRQ7.
What is the address of COM1?
From: http://www.techadvice.com/tech/C/ComPort_TS.htmCom1, IRQ 4, address: 3F8Com2, IRQ 3, address: 2F8Com3, IRQ 4, address: 3E8Com4, IRQ 3, address: 2E8
