I have an udma-100 hard drive but the m/board supports only ata-33 (apologies if these are not the correct technical terms). Is a udma-100 card simply a hardware addition or will it need drivers and, if so, are these likely to be modules or will it require a kernel rebuild? If distro dependant, it is likely to be used with either mandrake 9.1 or knoppix. TIA Syd
