Hi, i just bought an a7n8x deluxe mobo for the serial ata that was available on it. It appears that it is more difficult than i thought to bring those sata devices to work. I explain : i got that : AMD 2500+ Barton 1.5gb Ram Dual a7n8x deluxe ( sata 150 ) Western Digital 120gb Maxtor 30gb 2 Dvd drives graphic cards, and everything else that doesnt matter at all. So, i installed RAID Controller from Microsoft with autodetection. Silicon Image is updated. My bios is updated to v.1008. Also, my new samsung 250 gb SATA 300 ( with the lil things to switch it 150 plugged in ) is plugged, detected but not working as hdd. So my real problem as you might know, is that my sata is not working... so my new hdd cant work. i've tried : my maxtor alone with samsung with jumper my Western digital alone with samsung with jumper samsung alone with jumper for 150 samsung alone without jumper maxtor with samsung without jumper western digital without jumper. i also tried to installed windows only with the samsung connected, nothing else. Can't detect an operative hdd, so can't install. Windows cd tried to install raid controller and everything, nothings working. Oh yeah, and my new asus drivers are on. Another thing is that i got no floppy working. My floppy drive is broken, and i can't use it, and referring to my ASUS SATA installation's read me, i need one to install something to make those things working. Is there a way to install everything without that ? Maybe it's easy to figure out for some of you, but i tried everything and i really need your help . Thx for all and to all !
