Been running my F4 ds3 without any issues (8x400 mainly) with 2 ide drives , one op system and 1 rom & 2 Sata , 1 rom & 1 hdd. I decided to replace the ide master op drive with a new sata II drive, but since ive done this, the machine sometimes fails to boot, unless i unplug the sata storage HDD , and when i get the machine into windows, it`ll random reboot. As soon as i disconnect the sata storage hdd, or return to op ide drive ,and one sata hdd drive ,all is well again. Seems as if the board dont like 2 sata hdd being connected. Any ideas (have changed the sata connections to order in board, and visa versa) , as im stumped. All drives check out fine, and i dont know wether its a bois issue or what.
