Hi@all thanks to everybody for your numerous posts about integrating nVidia sata drivers. however i must say that i still havent succeded in anyway. So what i try is to integrate more than one SATA/RAID driver: VIASRAID SI3112r SI3114r AND NVATABUS/NVRAID Drivers sofar integrating the other drivers seem to work properly, i veryfied that integration of the viasraid driver was successful, but still as soon as i add the nvidia nvatabus.sys/nvraid.sys files etc. to my unattended cd i resice a BSOD right after setup finishes loading the drivers listed in TXTSETUP.SIF. To make this clear. setup states: LOADING WINDOWS and then the BSOD appears right befor the screen to edit partitions is supposed to apear, showing this BSOD: *** STOP: 0x0000007B (0xf7a2b528, 0xc0000034, 0x00000000, 0x00000000) im quite sure that this is due to the nvraid/nvatabus driver, as if i choose to not compress the nvatabus.sys/nvraid.sys to .sy_ puting them into the i386 i get the message that windows cant find them instead of the BSOD My hardware is the ABIT KN8 (NOT ULTRA) with a WD200G HDD, not sure which Bios version. besides this my unatteded install works fine so far. I tried integrating the drivers using the LEGACY folder as much as using the SATARAID folder (both from 6.70 package) and even the files from the floppydisk that have been include with the MB. I also tried hacking TXTSETUP.SIF my self using the numberous guides in this forum, as much as having the latest version of nLITe installing my drivers. both times no success!!! thanks to everybody so far.
