Message from Jack Ellis: "Native PCI Mode" is ONLY for big servers, which often have many more devices than we do and thus must re-arrange their device I-O addresses! Regular "home user" systems hardly ever need "Native PCI Mode" and MUST NOT be set for it unless the user KNOWS he has software which REQUIRES it! Most DOS drivers (including XDMA and XCDROM) are written to use "Legacy IDE" channels at I-O addresses 1F0h for the primary or 170h for the secondary, NOT any other addresses! Note that mainboard UltraDMA controller chips handle "UltraDMA" functions at PCI-assigned addresses DIFFERENT than the main-controller 1F0h or 170h addresses, since UltraDMA was added in 1994 AFTER the original 1F0h/170h IDE design. This is O.K., but "Native PCI Mode" is NOT!! Best wishes! Jack R. Ellis ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
