Noted.

Or, I guess, to assign to pcic and leave irq 5 Free for daughter cards to use. Thats fine for *me* because I don't use USB. But for others, it might be problematic. > IRQ 12: psm0 <PS/2 Mouse> > IRQ 13: (reserved, can't use) FPU > IRQ 14: ata0 (hard disk) > IRQ 15: ata1 Do I have an ATA1 I wonder. Can I disable it? Why would a laptop depend on using the alternate chain? It could be for the non-attached/removable CD player of course. (DELL do a carrier tray for a cable-attached floppy or CD. I will reboot with one attached and see what it does) > > Urg -- there's a lot of junk on IRQ10.
