Building a DiskOnChip Boot Image
The DiskOnChip distribution is made up of two primary modules: doc ,
which is the OS-9 low-level booter module, and rbdoc , the OS-9 device
driver for DiskOnChip. The following procedure uses the Configuration
Wizard to configure a boot device using DiskOnChip. The DiskOnChip
device appears as a disk drive to the high-level system and is accessed
using the RBF descriptor /dochc1.
1. On your host PC, select Microware Configuration Wizard from the
Program Menu.
2. At the main screen of the wizard, select the radio button labeled
Advanced Mode.
3. In the text box labeled Configuration Name (Required), type
DiskOnChip, Click on the OK button. A new window appears with a
menu bar. This is the Advanced Mode window of the Configuration
Wizard. It is here that we must tell the wizard to include DiskOnChip
support.
