Jordan or whom reads this:
Quest: 1 Bsd partition, 1 swap, and 1 Msdos partition.
I have attempted to partition it with fdisk {BSD} as well as pfdisk. Not too sure
what is the correct sequence. I have tried disklabel with and without fdisk
partitioning. Please let me know what I should do in sequence. Any help
appreciated! I have spent three whole nights with this... I hope I am not over
killing..
I wrote this disktab entry which gives the error -
partition c: partition extends past end of unit
partition e: partition extends past end of unit
ST11200N| Seagate Sun1 1.05 SCSI:\

Already low-level formatted at the factory.

Formatted at the factory with 12 spare sectors per cylinder
and two spare cylinders at inner tracks per unit.
