Debian don't find my Hard drive...

Hello !
Yesterday, I dowloaded the 1st CD of Debian Etch for ADM64.
I write it on a CD; I reboot my PC and the PC boot on my CD. I press the button "entry"

and the installation begin but it stop few seconds later , I've a black screen. So I

reboot :/.
Before, I write "installgui acpi=off" an press entry again, the installation begin but

debian don't find my hard drive, I've a list of drivers and I chose the driver "sata_nv"

because my mothercard is an Asus a8n-e (chipset -> Nvidia Nforce 4 Ultra), but debian

don't find hard drive again.
So, i can't do the partitioning because debian don't detect hard disk...
I've try with the "Netinstall CD", but It's the same result...

My configuration is :
Processor : AMD Athlon 64 3500+ on socket 939
Mother Card : Asus A8n-e
Graphic Card : Sapphire radeon x800gto 256 MB
Ram : 1GB of ddr 400
Hard disk : Maxtor DiamondMax Plus 9 6Y200M0 de 200GB
