TOWNS' LITTLE GUIDE TO REVISIONS - VERSION 1.0
by John Townsend, Atari Corporation
This article was lifted off Internet. Usually I prefer not doing
that, as otherwise ST NEWS might start to look a lot like some
other disk magazines that use the Net out there as their main
source. However, this article is bound to be very useful for many
people. I know I found it quite useful.
This is a small document that explains in very terse terms the
differences between the TOS revisions available for ST, MEGA,
STE, Mega STE and TT machines, what patches are needed for what
revisions, the formats they are available in, and any notes I can
think of.
I hope this will clear up some of the confusion with the
different TOS versions.
If you have any questions on this document, please let me know
through GEnie. My GEnie Address is: TOWNS.
Special thanks to Leonard Tramiel, Allan Pratt, and Doug Wheeler
for their involement with this little Document. Thanks again!
Comments are welcome..
ROM TOS (TOS 1.00)
The original ROM TOS, this version shipped in 520ST and 1040ST
machines.
It is no longer shipping in any machines.
Formats: 2 chip ROMs, 6 chip ROMs
Machines: 520ST, 1040ST
Utilities: FOLDRXXX.PRG
FOLDRXXX.PRG will add more entries into your OS Pool. In TOS
1.0 and TOS 1.02, the limit for the number of directories that
you can enter is around 40. With this program you can extend
that limit much higher. If you are using a hard drive, this
program is recommended highly. It will work with all TOS
versions and will improve the performance of your system.
Notes: Get a new TOS today! They are bound to much MUCH
faster, with faster, better disk I/O and many other
improvements!
MEGA TOS (TOS 1.02)
This is commonly referred to as MEGA TOS. This version of TOS
fixes some minor problems in TOS 1.0 and has support for the
BLiTTER chip and Real-Time Clock chip.
Formats: 2 chip ROMs, 6 chip ROMs
Machines: 520ST, 1040ST, Mega 2, Mega 4
Utilities: FOLDRXXX.PRG
FOLDRXXX.PRG is explained above.
Notes: See notes for TOS 1.00.
Rainbow TOS (TOS 1.04)
TOS 1.04 or Rainbow TOS, as it is commonly known is the latest
version of TOS available for 520/1040/MEGA owners. It has been
available as a dealer upgrade for awhile now. It has much more
robust Disk I/O, Autorunning of GEM programs at boot up, a fix
for the 40 folder limit, and much more. Most of all is it much
faster than previous versions of the Operating System.
Formats: 2 chip ROMs, 6 chip ROMs (available as Upgrade!)
Machines: Stacy
Utilities: TOS14FIX.PRG, POOLFIX3.PRG, CACHEXXX.PRG,
FOLDRXXX.PRG
TOS14FIX.PRG solves some small problems in the AES (for
additional information, please see the documentation that
accompanies the TOS14FIX.PRG program).
POOLFIX3.PRG fixes a bug in GEMDOS. Documentation that
accompanies the POOLFIX3.PRG program explains (in detail) the
problem that it fixes.
CACHEXXX.PRG is a new program that adds GEMDOS buffers to your
system. The caching of data and disk directories by GEMDOS (when
this program is used) will result in your system running much
faster! This program is highly recommended and requires TOS 1.04
or higher for full benefits!
FOLDRXXX.PRG is explained above.
Notes: Please use the utilities available and if you
haven't upgraded to this version of TOS yet..
please consider doing so. It's a very worthwhile
upgrade.
There are some disk-based versions of _early_
developer only releases of TOS 1.04 floating
around on BBS systems here in the United States
and abroad. Please don't use them! They are bad
news! They have some very nasty bugs and have
been known to corrupt data!
STE TOS, Rev 1 (TOS 1.06)
TOS 1.06 is the TOS version that is shipped with the 1040STE and
520STE machines. It is essentially TOS 1.04 with support for the
new hardware that the STE has.
Formats: 2 chip ROMs
Machines: 520STE, 1040STE
Utilities: STE_FIX.PRG, POOLFIX3.PRG, CACHEXXX.PRG,
FOLDRXXX.PRG
STE_FIX fixes the infamous Desktop Medium/Low resolution bug.
The problem is that there is a bug in the desktop code in this
version of TOS that prevents the user from booting into Medium
Resolution. The patch program STE_FIX will solve the problem.
Once it is executed in the AUTO folder, the problem no longer
exists.
FOLDRXXX.PRG, CACHEXXX.PRG, and POOLFIX3.PRG are explained
above.
Notes: This version is only available in 1040STE and
520STE machines. It isn't available for upgrading.
It won't work in older machines.
