Installing and Configuring Enhanced OS-9
Enhanced OS-9 for X86 PCAT 91
the device type to PCI in the config.des file shown above. You must
have the sources for RB1003 for the ability to make this change using
the cross hosted utilities.
If the PCI bridge does not work in PCI mode you can modify the
RB1003 init code as need for the PCI bridge device used. The sources
are located in MWOS/OS9000/SRC/IO/RBF/DRVR/RB1003, and are
included with the Embedded Systems package.
Use of IDE in PCI mode adds about 2K to the driver size.
RBF
OS-9 RBF native file system may be used on any IDE drive. For more
information see BootGen and IDE Descriptors.
PCF
A PC style file system is also supported. FAT32, however, is not
supported in this release. If access to partitions other then the primary
are required you may use the pinfo utility to obtain the information
required to create specific device descriptors. For more information see
IDE Descriptors. You may select the PCF file system as the boot
media.
For example. If the drive is Fat (not Fat32) you may place the bootfile
image on the root. Make sure it is called os9kboot. Next, create a
CMDS and SYS directory at the root level. Copy whatever CMDS you
need to the CMDS directory. Create a startup and or password file as
needed. This method allows you to use the same partition as
Windows95 or NT when you actually run OS-9.
Prepare Windows95/NT based system for use with OS-9.
