Freeing Interrupt Request 15

[Guest]

I need to use Interrupt 15 on COM3 for a legacy ISA card. Disabling the Secondary IDE Channel doesn't free the resource. Uninstalling the Secondary IDE only re-installs it automatically at reboot. The secondary IDE controller is disabled in the BIOS. Under NT 4.0 this works. Any ideas how to on Win 2000?

Hello

Well, IRQ 14 and fifteen will never ever be released to be
used for anything else But IDE Controllers

in the 10 years of EXP. have never seen it happen, if you
can get a mother brd. with no builtin IDE cont. then you
may be able to so

try using IRQ 3 , 4, 5, 7, 9, 10 ,11

Not true. It depends on the motherboard, system bios and
IDE controller hardware.

To the original poster, go into Device Manager and see if
there's an option under the controller entry (not the individual
channel entries) to set the controller to "primary only".

Well, in 10+ years I've never seen it NOT happen. E.g. I
disabled the secondary IDE channel on my motherboard
(Intel BX chipset w/ integrated ATA33 IDE) and am using
IRQ15 for an Adaptec 29160 SCSI controller. No
problems at all.

Thanks Rick!

Your help was on the money. The VIA chipset had an updated IDE driver that allowed me to remove the secondary IDE channel and free up the resources for the bus card.

Thanks again. Happy New year!
