OS9MAX allows to backup OS-9 disk devices to PC. The OS-9 disk will be linked
via TCP/IP network to the PC. As an option you may also connect the OS-9 disk
directly to the PC mass storage controller.
SUPPORTED OS-9 DISK FORMATS Our software supports all OS-9 disk devices on PC (directly and via network):
Floppy Diskettes SD/DD/HD
PC Cards (PCMCIA/JEIDA)
DTR provides full format implementation service on special devices at no additional charge.
Netdisk utility from OS9MAX toolbox
A single command gives you a backup of a complete OS-9 media. No bit of data will be lost. Everything of the disk has been saved: the complete file structure, all directories, all date and time stamps, all attributes, all logical disk structure information, the disk id and boot sector, and the file allocation table. After the backup has completed you will find a file on the PC with the same size as the original OS-9 disk. You will be able to rebuild your OS-9 disk from this backup within minutes. In additon we deliver a software which interprets the PC backup file as a physical OS-9 device. This allows to read and write data (files and directories) from/to the backup file. The complete OS-9 file structure is accessable from MS-Windows. Nearly all file system commands have been implemented. This software is a successor of the program OS9MAX which has been introduced to the world wide OS-9 usership by Radisys/Microware through their Pipeline publication.
The OS-9 disk '/h0' has been transferred via network to the PC. The file 'd:\image\os9disk\h0.img' has been created on the PC hard disk with 160 MB. This is exactly the size of the OS-9 disk. Before you wish to save this backup to CD-ROM you may collect other OS-9 media on the PC hard disk, or revise the backup files with OS9MAXIM. This software allows to access the backup files as if they were physical OS-9 media. OS9MAXIM allows to transfer/copy OS-9 files and directories from the backup to the PC hard disk and vice versa.
Start the utility by typing:
All OS-9 file manipulating commands (i.e. copy, del, dir, pd, makdir, deldir, dcheck, free, ...) are implemented. As long as the backup files are located on a hard disk they may be manipulated by the utility. After writing these files to the CD-ROM they are read-only. The directory structure on the CD-ROM backup is exactly the same as on the physical OS-9 media.
If your OS-9 hard disk has been formatted with 512 bytes/sector (this is standard nowadays) you may connect this drive directly to your PC SCSI or IDE controller. Please refer to the manuals of your PC, controller, and hard disk. Our software will read the whole drive by typing a single command:
OS9MAXHD d: hdd 'dread hdd_esy1.img'
OS-9 diskettes are directly accessable with every PC. This is the command line to backup a complete diskette:
OS9MAX a: 38u0 dread mydisk1.8u0
The following line shows how to rebuild the media from the file:
OS9MAX a: 38u0 ‘dwrite mydisk1.8u0
PC CARDS (PCMCIA):
If your computer is equipped with a PC Card interface (PCMCIA slot) you may access OS-9 formatted PC Cards (chipcards) directly with the PC. This allows also to backup (copy) SRAM cards to FLASH cards and vice versa.
Finally if your CD-ROM has been written and contains 680 MB of OS-9 disk, you wish to read this CD with a PC. No problem, any PC which is equipped with a standard CD-ROM drive is capable of reading this CD-ROM. Insert the CD into the PCs CD-ROM drive and start the utility as follows.
OS9MAXIM h:\h0.img (CD-ROM drive is 'h:')
OS9MAX64HD WINDOWS NT4 / 2000 / XP
Now you may extract files and directories from the OS-9 backup to your hard disk.
Note: for user convenience the OS-9 drive letter is '0:'.
copy 0:\*.* g:\
