Well, being neither their customer nor a kernel developer, I'm not sure my request would be considered serious. Anyway, probably I'll give it a try a bit later when I have an opportunity to dismount this board for more comfortable testing. I was also going to try to modify its BIOS to remove some unwanted behaviour unrelated to IRQs, and it might happen that I also discover something about PCI handling along with (It is just 64k size, after all, and I have a 8086 debugger) Thank you, Regards, Nikolai > Maciej >
