INSTALLATION Installing the CD-ROM software is fairly straightforward. On the disk will be two folders; AUTO and METADOS. The contents of the AUTO folder need to be copied to the AUTO folder on the current boot drive (C: on systems with hard drives). The entire METADOS folder needs to be copied to the boot drive. If the default settings in the CONFIG.SYS file (found in the AUTO folder) are not satisfactory, the CONFIG.SYS file may be edited with a text editor. The included CONFIG.SYS is as follows: ; CONFIG.SYS Configuration file for MetaDOS ; ; Note: lines beginning with ';' are ignored by MetaDOS ; Physical BOS (Basic Operating System) format ;*BOS, [physical BOS driver] [arguments], [physical ID]:[device #] ; ; device # meaning ; --------- ------------------ ; 0 - 7 DMA devices 0 - 7 ; 8 - 15 SCSI devices 0 - 7 ; ; *BOS, \METADOS\CDAR.BOS, Z:0 ; *BOS, \METADOS\CDARGEN.BOS, Y:14 ; *BOS, \METADOS\NETBIO.BOS, X:7 *BOS, \METADOS\ICDCDROM.BOS, A:1 ; Logical DOS (Device Operating System) format ;*DOS, [logical DOS driver] [arguments], [logical ID]:[physical ID] ; ; Note: the logical ID corresponds to a drive letter on desktop ; *DOS, \METADOS\HSMAY86.DOS, Y:A *DOS, \METADOS\ISO9660F.DOS, Z:A ; Optionally load in other AUTO folder files ; ;C:\AUTO\BOOT\RAM512.PRG ; Load in 512 byte RAM disk ;C:\AUTO\BOOT\GDOS.PRG ; Load in GDOS ;C:\AUTO\BOOT\DIAB630.PRG ; Load in Diablo 630 emulator for SLM ;C:\AUTO\BOOT\SDUMP.PRG ; Load in screen dump to SLM The line '*BOS, \METADOS\ICDCDROM.BOS, A:1' loads the ICD CD-ROM device driver (ICDCDROM.BOS), assigns it physical ID 'A' (physical device IDs have no connection to logical drive letters), and specifies that the CD-ROM drive has been configured as DMA device 1. The physical ID can be any letter from 'A' to 'Z' as long as all physical device drivers have unique IDs. The device number must match the ACSI/SCSI ID of the CD-ROM drive (0- 7 = ACSI 0-7; 8-15 = SCSI 0-7). The lines '*DOS, \METADOS\HSMAY86.DOS, Y:A' and '*DOS, \METADOS\ISO9660F.DOS, Z:A' load the High-Sierra and ISO-9660 drivers and assign them logical drive letters 'Y' and 'Z' and specify that they should communicate with physical device 'A' (ICDCDROM.BOS). The logical IDs can be any letter from 'C' to 'Z' as long as they don't conflict with other CD- ROM, hard drive, or RAM disk drive letters. MetaDOS also has the ability to run other programs at boot time much like the AUTO folder does. All that's needed to have MetaDOS run a program is to add the path and filename to the end of the CONFIG.SYS file. By using MetaDOS to run these programs, you don't have to keep them all in one folder, and you can easily specify the order in which they run. Once the CONFIG.SYS file has been set up properly and the computer is rebooted, drives Y: and Z: will be available. To use them from the Desktop, icons will have to be installed with the Desktop's 'Install Devices...' function. The Y: drive should be used when a High-Sierra CD-ROM disc is in the drive, and the Z: drive should be used when an ISO-9660 CD-ROM disc is in the drive. Note that the ICDCDROM.BOS device driver works ONLY on ACSI (DMA port) devices of ID 0 through 7. To use devices on SCSI ports, use the Atari CDARGEN.BOS driver. USING CD-ROM DISCS For the most part, CD-ROM discs can be treated as large write-protected hard drives. There are a few differences, though. Since CD-ROM discs come in several formats (High-Sierra, ISO-9660, Apple HFS), different drive letters are assigned to each format. Using the sample CONFIG.SYS, drive Y: would be used to access a High-Sierra CD-ROM disc and drive Z: would be used to access an ISO-9660 even though there is only one physical CD-ROM drive connected. Apple HFS CD-ROM discs are used almost exclusively on the Macintosh and are not supported by the included drivers. Most IBM PC and Commodore-Amiga and many Macintosh CD-ROM discs are in High-Sierra or ISO-9660 format and can be used with the included software. The format of a CD-ROM disc is usually printed on the disc and packaging. It is important to remember that although CD-ROM discs designed for other computer systems can be read on the Atari, any programs on those CD-ROM discs can not be run unless they were written specifically for the Atari. Some CD-ROM disc manufacturers compress or encode the data on the CD-ROM disc making the data unusable to any program other than the one supplied on the CD-ROM disc, which won't work on the Atari (unless it was written for the Atari).
