Instead we have two things - an ACPI snoop and a table of wonky laptops (eg those that use 40 wire ultrashort cables which are valid for UDMA133 but not detected as 80 wire). If your laptop is done that way then it just needs adding to the magic list and/or 2.6.23-rc1-mm should spot it by ACPI. I'd prefer the table entry anyway as I don't like relying on ACPI so an lspci -vvxx would be appreciated - 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
