-
-
- Do I need to update ?
- =====================
-
- You _must_ update if you wish to access your CD-ROM drive from the
- MagiC4 desktop. Even if you do not use the MagiC4 desktop, we
- recommend that you perform the update, since this update adds some
- new features, and fixes some bugs in earlier versions.
-
-
- What is needed to update
- ========================
-
- . This archive file, and:
-
- . An ExtenDOS Pro distribution disk, version 2.3, or
- . An ExtenDOS Pro distribution disk, version 2.3A
-
- You also need a double-sided floppy drive formatted to 800K
- (10 sectors per track) or at least 800K of free space on a hard
- disk drive. Due to the size of the files involved, you will not
- be able to carry out the update on a single-sided drive.
-
-
- How to update
- =============
-
- 1. Copy your ExtenDOS Pro distribution disk EITHER to an empty
- double-sided disk OR to an empty folder on a hard disk with at
- least 800K free space. In the following instructions, this
- area will be referred to as the "update work area".
-
- 2. Delete the following files (if present) from the update work
- area:
- SCSI.TXT
- SCSI_FAQ.TXT
- This is needed to provide sufficient work space.
-
- 3. Copy the PATCH240.TOS file to the update work area.
-
- 4. Run PATCH240.TOS from the update work area, by double-clicking
- on it from the desktop. For each of the files that need to be
- updated, the program will create a backup copy of the original
- file (with a .BAK extension) and then update the original file
- to the v2.4 level. The following files are updated:
- CD.BOS
- CDAUDIO.ACC
- CDAUDIO.PRG
- DISC.RSC
- EXTENDOS.PRG
- UNIDRIVE.DOS
- UNI_BDDS.DOS
- EXTINFO.PRG
- INSTALL.APP
- INSTALL.RSC
- The final message should be "10 modules patched successfully".
- If not, please read the error messages carefully; they should
- indicate what the problem is. You will probably need to begin
- the entire patch process again. If you cannot resolve the
- problem, please see below under "If you get an error message".
-
- 5. Delete the following files from the update work area:
- PATCH240.TOS (no longer required)
-
- 6. Replace the following files in the update work area with the
- corresponding files from this archive:
- READ.ME
-
- 7. (Optional, but recommended)
- Copy CHECKIT.TOS and CHECKIT.CTL to the update work area, and
- double-click on CHECKIT.TOS. It will perform a simple checksum
- verification on each of the files you updated or replaced in
- step 4 above. You should see the message "verified OK" for
- each of the ten files. If so, please delete CHECKIT.TOS and
- CHECKIT.CTL from the update work area.
- If you get any messages indicating that a module failed to
- verify, it's probable that your newly-updated copy of ExtenDOS
- Pro is invalid. Try obtaining another copy of this archive and
- redoing the update. Alternatively, you can have your disk
- updated by Anodyne Software: please see below under "If you get
- an error message" for how to order the update.
-
- 8. Congratulations! You have completed updating the files in the
- update work area. Now, for safety, first copy them to a backup
- floppy disk. Then, delete all of the existing files from the
- ExtenDOS Pro distribution disk, and copy the files from the
- update work area to the distribution disk. Finally, remove all
- the files from your update work area.
-
- ** VERY IMPORTANT STEP, READ CAREFULLY **
-
- 9. To install this version on your system, use the new INSTALL.APP
- program on your (updated) distribution disk; the READ.ME file
- on the updated disk explains how to do this.
-
- 10. Please take the time to read the new READ.ME file carefully.
- It contains information about all the new features of ExtenDOS
- Pro v2.4.
-
-
- If you get an error message
- ===========================
-
- If you get an error message during the patch process and cannot
- resolve the problem, you can mail us the disk so that we can
- update it.
-
- To have your disk updated by us, you need to:
-
- 1. Send in your original ExtenDOS Pro distribution disk.
- 2. Enclose a cheque or money order for $5 + $2 shipping & handling
- ($7 total). You may pay in Canadian dollars if you are located
- within Canada; all payments for shipments outside Canada must
- be in US dollars.
- 3. Enclose a note with your name, address, and phone number.
-
- In return you will receive a disk containing ExtenDOS Pro v2.4.
-
-
- Changes for v2.3A compared to v2.3
- ==================================
-
- New features
- ------------
- None
-
- Bug fixes
- ---------
- 1. The CDaudio volume control is now displayed properly in ST Low and
- Medium resolution.
-
-
- Changes for v2.4 compared to v2.3A
- =================================
-
- New features
- ------------
- 1. Supports the extended GEMDOS calls (a la MiNT) that the MagiC4
- desktop uses. This allows access to CD-ROMs from the MagiC4
- desktop.
-
- 2. Before attempting to read a CD-ROM, ExtenDOS Pro checks for the
- presence of an audio CD. If so, a volume label of 'AUDIO-CD' is
- returned (this will be displayed by the MagiC4 desktop and will
- act as a reminder). Also, any attempt to access data on the disk
- will be rejected with the GEMDOS error 'path not found', thus
- preventing interruption of any current audio playback.
-
- 3. Read errors now cause additional retry attempts, thereby increasing
- the likelihood of successful reads under adverse conditions.
-
- 4. Now supports the following additional drive:
- Drive Device type Audio PhotoCD
- ----- ----------- ----- -------
- Nakamichi MBR-7 120 Y Multi
-
- The device type for the Chinon 525 has been changed to 53.
-
- 5. Additional checking for a CD-ROM change is now done for all Sanyo
- drives. This is designed to circumvent a problem in the firmware
- on at least some Sanyo drives: they do not report media change.
-
-
- Bug fixes
- ---------
- 1. If the year in the file date on a CD-ROM is less than 1980, the
- TOS time/date is returned as 1980/01/01 00:00:00 rather than
- something strange.
-
- 2. The SCSI bus is reset under some additional timeout conditions;
- this increases the likelihood of recovery from these conditions.
