IBM_challenge

Hi, I have an IBM X30, I installed a wireless card (PCI I beleive) however in the windows driver instillation it says that there are not enough system resources for the card - I think this is the IRQ settings but do not know what to do to solve it - can anyone help?

i think the system resources and IRQ (Interrupt Requests) maybe different ... so there might be something else wrong

What is an IRQ? IRQ Settings, how to view IRQ assignments and resolve IRQ conflicts

IRQ stands for Interrupt ReQuest and refers to special numbered channels that are used by devices to get the processors attention.

For example, when you press a key on your keyboard this sends a signal to the processor via an IRQ channel (usually IRQ 1) to let it know that it needs to process some data.

IRQ conflicts can occur when new hardware is installed or reconfigured, for example, it can cause problems if you have your mouse on COM 1 (IRQ4) and a modem on COM 3 (IRQ4), below is a list of the default assignments for IRQ channels in Windows XP.

Default ISA IRQ Assignments
IRQ 0 System Timer
IRQ 1 Keyboard
IRQ 2 Cascaded with IRQ 9
IRQ 3 Default COM2 and COM4
IRQ 4 Default COM1 and COM3
IRQ 5 LPT2
IRQ 6 Floppy Drive Controller
IRQ 7 LPT1
IRQ 8 Real Time Clock
IRQ 9 SEE 2
IRQ 10 Open
IRQ 11 Open
IRQ 12 PS/2 mouse or Open
IRQ 13 Math Coprocessor
IRQ 14 Primary Hard Drive controller
IRQ 15 Secondary Hard Drive controller
