Is SATA hard disk is suooprted by SCO OpenServer 5.05? If No, how to couter this problem. If yes, please provide the installation steps.
Only if attached to a supported RAID card - and you will find very few with driver support for 5.05...
Stick with IDE or SCSI. IDE disks MUST be smaller than 127gb.
