MetaDOS 2.60
These are the essential elements to get any SCSI CD ROM drive going on
an Atari TT or to use an `Atari CDAR 504' CD ROM on an Atari with
ACSI port. It does NOT support SCSI drives connected to an ACSI
port. It does NOT support the Atari Falcon030 at all (in these
cases, you'll need third-party drivers). You may use it 'as is', don't
expect any updates.
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 2.60 driver for CD-ROMs in High Sierra format (usually not
needed).
\AUTO\ISO9660F.DOS
Version 2.60 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 2.60 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 won't access drive letters beyond P: (MetaDOS can
install drive letters up to Z:).
Technical problems: It's not possible to redirect GEMDOS standard
input/output to MetaDOS files (only applies to people using
command line shells).
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.
