MetaDOS 2.3
These are the essential elements to get any SCSI CD ROM drive going on
an Atari TT. You may use it 'as is'. Don't expect any updates, because
we are putting all our effort in a new driver which will work under
MultiTOS. Before that driver is available you might spend some time
with MetaDOS 2.3.
This release fixes only some small problems present in previous
versions.
FILES
\AUTO\CDARGEN.BOS
Generalized version of physical device driver. This driver only
supports SCSI CD ROMs connected to the SCSI port of the Atari TT
(or the Atari 'CDAR 504' connected to the ACSI port of any Atari
computer with ACSI port).
\AUTO\HSMAY86.DOS
Version 1.92 driver for CD-ROMs in High Sierra format (usually not
needed).
\AUTO\ISO9660F.DOS
Version 1.92 driver for CD-ROMs in ISO 9660 format (the ISO format
is the 'real' final version of the original High Sierra
specification).
\AUTO\METADOS.PRG
Version 2.3 of MetaDOS.
\AUTO\CONFIG.SYS
Configuration file. You will have to edit this file to assign
drive numbers and/or drive letters. In addition, you can edit the
path names for all driver files (if \AUTO\BOOT\ isn't ok for you).
INSTALLATION
Copy METADOS.PRG, CONFIG.SYS, CDARGEN.BOS, ISO9660F.DOS and
HSMAY86.DOS into the AUTO folder, edit the ASCII file CONFIG.SYS for
your specific settings. Reboot.
KNOWN PROBLEMS
METADOS.PRG
Some programs do not work properly when MetaDOS is installed
(because they are violating the rules for register saving for
GEMDOS calls). Contact the programmers of these programs to get
them fixed.
Some programs won't access drive letters beyond P: (MetaDOS can
install drive letters up to Z:).
Technical problems: (1) It's not possible to redirect GEMDOS
standard input/output to MetaDOS files (only applies to people
using command line shells). (2) Files on MetaDOS devices aren't
closed when a program bombs or is aborted with CTRL-C (this is
usually no problem with CD-ROMs, because they are read only
media).
ISO9660F.DOS and HSMAY86.DOS
Sometimes, media change doesn't work properly. If this happens to
you, eject the disk, insert it again and wait a few seconds before
the next try.
CDARGEN.BOS
The old audio commands (documented in the developer's
documentation) are only supported for backwards compatibility
only; some flags do not work at all.
Technical problems: the MetaDOS XBIOS calls that cause I/O with an
ACSI device require that buffers are allocated in ST compatible
RAM (see Mxalloc documentation).
Some CD ROM drives need special initializations to be able to
access disks in XA format (Photo CD). CDARGEN.BOS has no special
support for those drives.
