Is there another way to delete existing partitions from the HD using fdisk
other than ‘fdisk -z /dev/hd0’ ?
How did Neutrino installation CD manage to partition & install the entire OS
within such a short time??

dd if=/dev/zero of=/dev/hd0 bs=512 count=1

Short install time is due to the fact that they don’t format/verify the
disk and don’t do anything other than copying files. All detection is
done at boot time.

ThanKs! I didn’t know that dd has so much usage.
One more qns, how did the CD installation manage to re-partition/create new
partitions in the HD & copy files over without restarting the system? I run
devb-eide after I re-partition & format so as to detect the new partitions,
mount the new partitions and starts to copy files over. However, the system
keeps hanging during the copying part.
