I've managed to get my Sata 8237 driver installed without changing any "sif" files. To be more precise the file in question is VIAMRAID.SYS and related INF and TXTMODE files: 1) I've created a $OEM$/$1/sata/ directory tree inside the source folder 2) copied the contents of the sata diskette (or the DRVDSK from the hypherion540 folder from Viaarena) in the sata folder (see point 1) 3) copied the VIAMRAID.SYS into the I386 directory 4) Once in nLite, when in the Drivers panel, I've selected the driver (in Txtmode) All done! found the info browsing the net and got not a clue how it works but who cares... No need to press any F6 key anymore. By the way, what are these viasraid.sy_ and viapdsk.sy_ for? The post is a couple of years old, I guess those drivers have been replaced by VIAMRAID.SYS by now. Or I am missing something? How many drivers are required by the Via8237 chipset? There are other INF files relative to VIAAGP, VIAMACH, and VIAUSB but they aren't installed even by a proper install from windows...apparently Hypherion itself choose not to install them because they aren't required or because those provided by windows are newer (e.g. agp). My knowledge is very approximate...I'd like to know a bit more. any reply appreciated.
