HP DC7800P no harddisk

[Mimamau]

I created an USB-Drive for Mountain Lion with Unibeast. Installation boots fine, but doesn't show my harddisk.
It has an Intel Q35 chipset, there are no BIOS settings for IDE or AHCI. What do I need? Any kexts?

when i used this system with snow leopard

I changed the Bios setting for SATA emulation to RAID

----Enter the bios

cursor over to storage
cursor down to storage options and enter
here you can enable/disable removable media boot and legacy diskette write
as well as change SATA Emulation (I believe IDE and RAID are the options)

make changes and save the Bios settings

good luck.......
