HP 6005 MT Pro

[xmisterx]

Hi,
I try to install FreeNas to a USB stick by booting from the FreeNas AMD64Bit Iso, the PC goes through normal boot, then comes up with BTX loader, and then the system beeps 5 times.

I then installed FreeNas to the USB off another PC, and then try to boot the HP 6005 Pro PC into FreeNas and it comes up with BTX loader, and then the system beeps 5 times.

I have seen somewhere that it may be a BIOS setting? Can someone please guide me on what setting may need to be changed?

Thanks
