I might say that NT, the other half of my 486 is quite content with the disposition of the I/O card, even with the ( I personnaly didn't know it was set at ) strange IRQ setting. One does not understand why the current set of kernels could not do the same!
I dont understand where the problems could crop up. If I were to try to detect the IRQ for each of the well know Serial I/O addresses, I would simply redirect the interrupt vectors ( temporarily ) to addresses that I am aware of. This appears to be exceedingly simple, but I suppose the concept of modules, may make that dangerous to do.
Has the kernel addressed IRQ daisy chaining ? or is still 1 IRQ/device. gat
