ipc 10.5.6 msi dka 790gx platinum boot problem

[neo8393]

hello guys,
I have tried to install ipc 10.5.6 on my pc but always the same error: "waiting for root device".
I have tried with "-x;-F;-v;-v cpu=1" sometimes alone sometimes together but it do not want to work. AHCI is enabled in my BIOS.
Here my PC:
mainboard: MSI DKA 790GX PLATINUM
cpu: AMD Athlon 64 X2 Dual Core Processor 7750 Black Edition
hdd: SATA hitachi 1TB
I am downloading ideneb 1.4 10.5.6 and will try it again when it is finished.
Please help me.
