If I put a third drive in the system as IDE1/secondary master then that is detected. However the IDE0/primary slave is never detected. Using the 2.2.19 kernel the IDE0/primary slave device IS detected properly. The 2.2.19 and 2.4.x kernels used were compiled with support for SMP. I experimented with several different compile-time and run-time options with no luck. Below is some more detailed info. -Adam Scislowicz * note: Please CC me in your response as I do not subscribe to this mailing list. * note: I have tested this on several different machines(all SMP Intel BX or GX chipset boards) [ My IDE Controller Info (2.2.19:/proc/pci) ] Bus 0, device 7, function 1: IDE interface: Intel 82371AB PIIX4 IDE (rev 1).
