During the Windows XP setup you will need to provide the RAID driver using a pre-formated floppy disk.
Windows will ask you if you want to provide additional drivers and give you the key combination to use to do that.

Hi,
check if the drive is showing in the bios of the server,
shut down the server, take out the power cable, press and hold the power button so as to realease flea power, open the server, and reseat the data cable at both ends and if there is another power cable available in the server swap it with the existing cable plugged into the scsi drive.

and now try to start your server.
Further Queries are welcome

yes you can do that but you need the drivers for the scsi interface. when you install windows xp (for example) i think you may have to press the f6 key on the installation to add these drivers.

Otherwise, installation wont take place.
