None Strange IRQ info on NT

NT Diagnostic gives following information:

IRQ Device Bus Type
06 Floppy 0 Isa
10 WVLAN41 0 Internal
11 E100B 0 Pci

What surprises me is that WaveLAN interrupt is of type Internal (whatever it means?). Maybe there is some kind of driver to produce/process those interrupts in NT.

Is there a way to find the interrupt which TI-1221 is using on NT? At least "Administrative Tools/Windows NT Diagnostics" only gives IRQ for WaveLAN adapter and on the "Control Panel/PCMCIA" there is only memory area as a resource for PCMCIA Controller.

On the linux side:

If I set the WaveLAN to use IRQ 10, it doesn't work. All PCI interrupts are giving "PCI irq N test failed", unless I set do_scan=0.

I was able to get some pings through when I set it to use the same interrupt as eepro100 is using (IRQ 11), but the ping packets only went through when there were network traffic going on (== interrupts generated by) the eepro100...

None I think you are out of luck

Hmmm.  I was actually surprised that this worked at all under NT.  Now
I think I understand.

I bet that NT has not figured out the interrupt routing either.  And
when it says "Internal", it means that it is faking the interrupt in

Without a datasheet for your PCI bridge chipset (the VLSI one), I
don't think there is anything I can do to help you.

Your best bet would probably be to use an ISA-to-PCMCIA adapter card
instead of this PCI adapter.
