I used the backup program to make the ASR tapes and floppy.
Now in order to test the restore process I booted the IBM server from the Windows installation CD which did not regognise the RAID-5 disk array.
I extracted the drivers from the IBM server CD to a floppy diskette then rebooted the server from the Windows CD-ROM.When prompted I pressed the F6 key to install the driver for the RAID controller and then the setup program was able to recognise and see the HDD.
Now how can I go back to the ASR option "F2" since this is what I wanted to do in the first place!!!
