DOS has a limit of 1024 cylinders and most utilities translate the extra cylinders into heads. BSD/OS has only a 4-bit field for the number of heads which make 16 heads the max. It seems that I can't get a consistent view of the disk to make dual-booting possible. I think I had tried all choices (BIOS, CMOS, FDISK, etc) on version 2.1 installation process without success. Any help will be appreciated. -- - Kee kee@eecs.harvard.edu
