Good day,

I just want to know how can I optimize my IRQs sharing?

here are the lists:

00 system timer
01 keyboard
02 programmable interrupt controller
03 com2
04 com1
05 ACPI IRQ holder for PCI IRQ steering
05 LAN card
06 FLOPPY disk controller
07 LPT1
08 system CMOS real time clock
09 SCI IRQ used by ACPI bus
10 MPU-401
11 ACPI IRQ holder for PCI IRQ steering
11 ACPI IRQ holder for PCI IRQ steering
11 ACPI IRQ holder for PCI IRQ steering
11 AC97 audio controller
11 PCI to usb host controller
11 PCI to usb host controller
11 Nvidia video card
12 mouse port
13 numeric data processor
14 VIA bus master PCI IDE controller
14 Primary IDE controller
15 VIA bus master PCI IDE controller
15 Secondary IDE controller

As you can see, there are IRQ that shares with many devices and I want to optimize them .

My motherboard is ECS k7AMA2

Please help me on this one.

Thank you!the IRQ holder table and IRQ/PCI steering is a bit of a legacy from older DOS system ideology, there were originally 8 now there are 15 but some that are fixed and two that cannot be changed at all as they dont really exist in reality as they are jump paths to the added 8 which in reality shows as 7 less 2 there are only 13 but then 5 of them cannot change.
it has been a constant since Windows XP and PnP CAME out to leave well alone and let the operating system and the BIOS swap out the addresses if and when required, and when devices were in use or not, added to or removed from the motherboard / bios
it was falling apart until USB and Firewire devices saved the BACON and almost done away with it altogether, SATA is another nail in its coffin and about time to.
a rough but very good guide can be found here:-

IT IS BETTER LEFT WELL ALONELet Windows handle the IRQ's. Don't fuss with it unless you know what you're doing.
If you want an "adventure", then play around
