The spec for the E-155 says it has only one hard disk, so you could not
use RAID. Your options could only be SATA configured as IDE, native SATA
or SATA AHCI: some of those options may not be present.
You should need no special drivers.
When booting the machine, go into the BIOS and check that it reports the
presence of a hard disk. I think that either there is no hard disk or
it, or its connection, has been damaged in transit to you. If a hard
disk is present test it with either its manufacturer's diagnostic
utility or the Gateway GWSCAN utility.
