RBF
OS-9 RBF native file system may be used on any IDE drive including
PCMCIA devices. For more information see BootGen and IDE
DESCRIPTORS. When using RBF with PCMCIA only OS-9 will be able
to access the media. When running FDISK on PCMCIA media, be sure
to write down the ID type. You will need this value if you decide to later
restore the media for use with DOS/ Windows. fdisk -d=/pchcfmt -s will
show the type. If you need to restore the PCMCIA IDE card for use with
DOS/Windows you must restore the ID type. If you have PCMCIA
support at the DOS level you may be able to use FDISK. If not you can
use Linux to change the ID type. We may add this feature to OS-9 fdisk
in the future but be warned: once the device is changed to RBF if you
do not have the tools then this disk will have to stay RBF.
PCF
PC style file system is also supported. FAT32 is, however, not
supported in this release. 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.
