IRQ 14 is primarily used by the Advanced Technology Attachment (ATA) interface, specifically for the primary IDE (Integrated Drive Electronics) hard drive. It allows the operating system to communicate with hard drives connected via the IDE interface, managing data transfer and device control. In modern systems, however, IRQs are often managed by the operating system, and the traditional usage of IRQs has diminished with the adoption of technologies like SATA and USB.
IRQ 14
IRQ 1 is used exclusively for the keyboard controller.

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

Depends if it's sharable or not. You could try moving the card to another slot.
LTP1 should use IRQ7.
IRQ 0
By default, the IRQ for the floppy disk controller is IRQ 6.
