diskette (by COPY), it was structured to boot
for a particular type of drive. The setting for
drive A: within that on-disk operating system
must match the boot structure, or the boot will
fail.
When you use COPY to copy an operating system
from (for instance) an Elite One drive to an
Elite Two drive, COPY restructures the system
into a format compatible with booting off of the
Elite Two. However, COPY did not change the
configuration setting for drive A: on that new
system copy. If drive A: was not set as an Elite
Two on the system diskette which was cop-
ied, then you will need to use PROFILE to change
drive A:‘s setting in the Elite Two system disk-
ette to an Elite Two. Otherwise the diskette
will begin to boot, but end up crashing. The
same is true for other changes in booting struc-
tures.
Whenever PROFILE has to read and write a disk-
ette in a particular drive in order to make
changes to an on-disk copy of CP/M, it relies
completely upon the definition of the drive
within the in-memory CP/M to determine the
CP/M’s structure on the diskette. PROFILE ex-
pects the CP/M ‘s structure to match how the
drive is defined under the operating system.
This means that Elite Two system diskettes
should only be updated in drives defined under
the in-memory CP/M as Elite Two’s. The same
goes for the other types of system diskettes.
Also, keep in mind that any changes you make to
the in-memory CP/M take effect immediately.
