Model II TRSDOS
4. Conversion Step.
4-A. If you want the destination diskette to have a full system, use this command:
XFERSYS
:d
where d is the drive which will contain the destination diskette. Multi-drive
users should always use drive 1,2 or
3,
since no disk swaps will be required.
Single-drive users must use drive 0; XFERSYS will prompt you to swap
diskettes whenever required. Remember: the SOURCE diskette is your 2.0
working master; the DESTINATION diskette is the one you are converting.
4-B. If you want the destination diskette to have a minimum system diskette, use
this command:
XFERSYS
:d
MIN
where dis as explained in step 4-A.
4-C. If you want the destination diskette converted to a non-system data diskette,
use this command:
XFERSYS
:d
DATA
where d specifies the destination drive, either 1.2 or
3.
5. XFERSYS runs in three phases (detailed below). The screen will show which
phase is in progress. The complete conversion may take up to 10 minutes,
depending on the number of system files on your source diskette.
If there are not seven contiguous free tracks following the directory, XFERSYS
will list the files that must be moved to free up this area.
In
this case, XFERSYS will terminate without making any changes to the
destination diskette. Write down the file names listed. Reset the Computer,
insert the older version ofTRSDOS, and kill the files listed by XFERSYS (make
copies first unless you don't need them!). Then start over at step 3.
6. If the conversion is successful, the message CONVERSION COMPLETE will be
displayed. The resultant (destination) diskette is now a TRSDOS 2.0 full system,
minimum system or data diskette, depending on the option selected.
Creation
of Minimum
System or Data Diskettes
XFERSYS can also take a 2.0 diskette and remove some or all system files to create a
minimum system or a data diskette. Conversely, it can add some or all system files
to a data diskette. The steps are exactly like those described previously, except:
• The entire operation is performed underTRSDOS 2.0.
• There is no conversion phase. .
• You may use ANALYZE to determine which files (if any) need to be moved.
