Yes and in the software setup it was setup at irq 5. Got a new TV card whichput itself on irq 5, shoving my NIC card to irq 3.
Ahhh OK.
The only irq where the software setup did not complain as being used by something else was irq 15. Using that irq caused a lockup at boot. I gave the TV card irq 9 in the BIOS and have now a working com port again.
The reason that using IRQ 15 caused a lockup is that 15 is used for the second IDE channel on the motherboard.
Although my motherboard is outfitted with two ISA slots 4 PCI and one AGP, space problems does not make that possible.
Understood.
There is no PNP OS YES/NO in my BIOS but I had not set the PCI cards a specific irq which is more or less the same
Weird? What make is this motherboard? Usually there is some sort of setting like the one described. Oh well.
It is a board from Itox. Taiwan with an (upgraded) Award bios. I put the irq 9 for the TV card and everything is running well. There is still a program that does not want to contact this port but that is a software case or a cable case ;-).
Stupid IRQs! 2004 and IRQs are still around and a pure PITA!
The question that arises, I remember vaguely that irq 9 is used to connect to the irq from 10 and higher. Would the choice of irq 9 have consequences? And I am still missing one or two com ports for the things that I am planning to do. Aren't there USB to comports adapters which could solve that problem? For the time being I can proceed ;-). Everyone, thanks for your help.
IRQ 9 is tied to IRQ 2 (which is hidden). If you are still missing the port, then I am not sure what all you can do. You will need to be sure that you have a IRQ set aside for that com port.
I am not sure about USB to com port adapters. I unfortunately have not had a situation where I have had to see about using such a thing.
If IRQ 9 is free, then you should be able to use it.
Well let me think what all else we can try to get this to work.
It works ;-)
