OS/2 CD_ROM file system driver - Read Me Information
----------------------------------------------------
2/28/97
CONTENTS:
README.1ST - this file.
CDFS.IFS - the CD-ROM file system driver.
DESCRIPTION:
This CD-ROM File System Driver (CDFS.IFS) adds support for mixed-case
file names longer than 32 characters. The reason for these changes
to the CDFS is because some of the JAVA toolkit CD-ROMs have been
mastered using names greater than 32 characters in length and using
mixed case names. The CD-ROM included in the "Hooked on JAVA"
publication is one such example.
In addition, support has been added for the new Microsoft Joliet
CD-ROM format. (see "http://www.ms4music.com/devl/dvjoliet.htm" for
more details.) Joliet is a Microsoft extension to the ISO 9660
CD-ROM file system which adds Unicode and longname support. Joliet
support is Presently both Windows 95 and Windows NT 4.0 supports the
Joliet format. To enable the Joliet support, you must use the '/w'
option in CONFIG.SYS to enable the Joilet support. Since many of the
CD-R code is starting to ship with support for MS Joliet, this new
format should become more and more common (at least for CDROMs
created to be used on Windows). However, I need to point out that
this is a new format. I only had the Microscoft specification and
CD-ROM created from a demo CD-R program to develope and test this code.
TO INSTALL:
1. Change to the d:\OS2\BOOT subdirectory, where d: is the drive
letter where you installed OS/2.
2. Rename CDFS.IFS to CDFS.ORG.
3. Copy the new CDFS.IFS into the d:\OS2\BOOT subdirectory.
4. Then if you Joliet support is desired:
Change to d:\ and type TEDIT CONFIG.SYS. Find the
IFS=C:\OS2\BOOT\CDFS.IFS statement and add '/W' to the end of the
statement.
5. Reboot system.
PARAMETERS:
/W - Enable Joliet Unicode name support
/Q - Disable all signon messages
/V - Enable all signon messages
(default) - Display Beta driver message only
Revisions 2/28/97
- Modified CDFS.IFS to work with Aptiva Recovery CD-ROM when '/w' option
was used. This failed because this CD-ROM did not contain a valid
Volume Descriptor Set Terminator as required by ISO 9660 Spec.
- Fixed problem where CDFS did not support mixed case names when using
the REXX SysFileTree function.
- Fixed problem where under some stress conditions, CDFS would return
Path not found when the path was really OK. This condition could be
easily reproduced by running the FixPak installation program.
- Modifed CDFS to recognize Joilet UCS-2 Levels 2 and 3 escape sequences.
(The CDFS code continues to only sypport the Latin 1 character set.)
