On a Rainbow, drives C and D always refer to the third and fourth floppy drives. Your hard drive is set up properly right now. To boot from the hard drive, you'll need to choose 'W' for Winchester hard drive at the boot menu. If you are using a Rainbow 100-A, this option is not present in the boot menu, and you're out of luck as far as booting to the hard disk is concerned (I beleive). If you have a 100-B or 100+ (which is just a B anyway), The W option should be present on the main menu. SImply select W and another menu may or may not appear allowing you to choose which partition to boot from. You can quickly tell if you have a 100 A or B by either: 1. Looking at the model number on the back of the unit near the power plug (PC-100-A is a Rainbow 100 A, PC-100-B or -B2 is obviously a Rainbow 100 B) 2. Looking at the firmware version on the boot menu ( Version 4.XX or less is a Rainbow 100 A, Version 5.XX or higher is a 100 B). Hope this helps! -Jeff jba at sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
