MESSAGES

Cannot SYS to a network drive

You cannot use SYS on a network. Pause the fileserver and then

issue the SYS command.

No room for system on destination disk

There is not enough space for the system files on the destination

disk. Format a new disk with FORMAT/S and then reissue the

command.

No system on default drive

DOS cannot locate the system files to be transferred. Select a

disk that has the DOS files on it and try again.

NOTE

The target disk must either have an empty root directory,

have been formatted with the /S option of the FORMAT command, or

have been formatted with the /B option of the FORMAT command. If

you use the SYS command on a disk that has not been properly

formatted, you may lose data from it. The SYS command does not

copy the COMMAND.COM file, which is required to make a disk

bootable.
