If you have an 8-port controller on a board and one disk, forcing all of them enabled regardless of BIOS settings is just 7 redundant port scans. It should at least be an option - the default being to open up all gunports, an option to respect BIOS settings and only use the ones requested and enabled.. (I can see an edge case where a user disables a disk in the BIOS to stop another OS from looking at/for it, but wants the Linux system to boot from it) -- Matt Sealey <matt@xxxxxxxxxxxxxx> Genesi, Manager, Developer Relations - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
