I know this is a very old thread but hoping it will answer the question of any one else searching for a solution.
I have recently been upgrading four Dell GX620 machines with an ATI HD3450 dual video card. I came across the
same problem on two of the four machine - which was odd - I have searched google for an answer but non was found.
I compared hardware and BIOS of Dell equipment but there was no difference - so how could 2 work and 2 not?
Battling on I ended up pulling the power, removing the battery backup and jumpering the RTSCRST on the motherboard to wipe all BIOS configs. After re-applying power the BIOS was reset as date/time was not set. Since this, the fault has gone away.
So for whatever reason this occurs, it seems it can be overcome by resetting the BIOS. A BIOS upgrade did/does NOT fix the issue. Loading BIOS defaults did/does NOT fix the issue.

Try to check the I/O interface or periperals of your hardware in the BIOS i think there is a conflict in the IRQ... if you don't know how to setup BIOS just keep in touch.... TY

Hi there, my name is Kasu Embaye. I have a problem of I/O card parity interrupt f000:f188 on my dell optiplex 780,how to fix this problem? can you help me?

Hi mmm it sounds to me like your motherboard has got some problems. sometimes running system tests through the boot menu may help but should indicate weather you need a new motherboard or not. Sometimes a good clean inside computer is the way to go as well... Hope this helps
Kindest regards

Hi there, how can I fix the problem of I/O card parity interrupt at F000:F188 when appeared at starting my computer?

It sounds like one of the 3rd party cards has died. If you have a firewire card I would start by removing that and performing several cold boots (boot the computer, then completely shut it down as opposed to rebooting) If that doesn't fix it continue with the other cards, one at a time and replacing the previous card, until the issue is resolved. If you're still under warranty, call dell and request a repair.

Error I/0 card parity interrupt at F000:F188 Type (S)hutoff NMI (R)eboot, other keys continue

Someone else on fixya suggested RAM -

I'd definitely at least run a RAM test - if you can get that far (bootup using a bootable CD with memtest 4). Otherwise just see if removing the RAM has any impact.

Also could try flashing the BIOS, again if you can get that far.

It's clearly not relating the operating system, so either BIOS, or hardware failure.

Hi there,
This error refers to an expansion card having an issue. If you've got any cardbus, wifi, bluetooth, etc cards take them out and see if that resolves the issue. More info here:

NMI parity error (Non-maskable Interrupt) is generally a motherboard or a RAM issue.
You can try flashing the BIOS to A04 (You'll need to copy the flash executable to a bootable CD or bootable USB drive to run the flash.
Try individual or different RAM modules
if all those do not resolve, issue is most likely the motherboard.

My dell optiplex 360 cannot start and is displaying the message i/o card parity interrupt at f000:268f

mostlikely an input/output card issue, or a motherboard failure. first thing to do, disconnect any i/o card you may have like video card and other expansion cards. Then connect the cards one by one and test the system if the error has stop. If your system has an intg video controller, try using it first to rule out an expansion video card issue. if you've ruled out any expansion devices and you have reseat the CMOS settings of the system, most likely, you need to get a new motherboard or request warranty replacement if still applicable.
