solving irq sharing

[plaster]

has anyone tried to work with this? i remember a friend who has a studio told me his irq's have only one hardware per channel. meaning, nothing more than one piece is on a irq channel. i'm not too familliar with all that stuff, but perhaps it could boost pc performance.

hi, as long as i know irq's are valid for ports on ISA slots (not 100% sure)...
if your system is already working fine i don't think you can improve the performance by changing your irq settings.
which devices are you using?

[plaster]

i don't have any problems really, but i was thinking about why do some channels share a few devices. wouldn't the performance boost if you applied each device onto a separate channel?

As I understand it, IRQ sharing only really became a problem around the time of Windows 2000, where motherboards first implemented ACPI, which slung everything onto the one IRQ to let the OS sort out interrupt requests. Modern boards use a newer, more optimal version of this system called APIC, which seems to have solved most of the problems for audio work.

Examples of IRQ conflict problems would be pops and glitches in your audio app when your hard drives are working hard, there is a lot of network activity or you are moving windows around. If you're not seeing this (and I doubt you are at all unless you are running an older machine) then don't worry about it!

Hope this helps.

That's not going to work unless he installed his os with ACPI/APIC disabled.

i tried once to disable apic and install windows as standard pc. it didn't work quite well but some studios know to use that feature. i dunno why axtually.

don't fix stuff thats working fine.
I've burnt my fingers...

about IRQ-s I kinda remember it was important not to have your video card sharing IRQ with audio card...
