One or more CON code pages invalid for given keyboard code
Cause: KEYB. You attempted to change your keyboard with a code page combination inconsistent with the CON
device code page combinations; the code pages prepared by MODE and the code page supported directly by your
hardware. The current CON device code page combination is invalid for the given keyboard code.
Action: Warning message only. The keyboard is loaded, but only the valid code pages are available for the
Only non-startable partitions exist
Cause: FDISK. You asked FDISK to change the active partition, but none of the defined partitions can
successfully start from the hard disk.
Action: Create a startable partition, such as the primary DOS partition.
Only partitions on Drive 1 can be made active.
Cause: FDISK. The system can start only from the first hard disk, so there is no reason to mark a partition on
drive 2 as active.
Action: Use FDISK to mark a partition on drive 1 as active to start from the hard disk.
Option ROM or RAM detected within page frame
Cause: EMM386. The EMM386.EXE memory manager is detecting a device in the address area where it is trying
to locate a page frame. It has found another 64K contiguous space but is notifying you that its original try was
Action: No action needed.
Out of environment space
Cause: DOS. This is an information message caused by one of the following:
o PC DOS was unable to accept the SET command you just issued because it was unable to expand the area
where the environment information is kept. This normally occurs when you try to add to the environment
after loading a program that makes itself resident (PRINT or MODE, for example).
o You tried to expand the environment while in a batch file.
Action: Edit the CONFIG.SYS file to include or increase the e: switch setting in the SHELL statement, or remove
unnecessary strings from the environment. Restart the system.
Out of memory
Cause: COMMANDS. There is not enough memory for the operation to process.
Action: You need to increase the amount of available memory in your system. To increase your system
memory, do one or more of the following:
o Change the buffers parameter in the CONFIG.SYS file to a smaller value.
o Remove device driver programs.
Restart the system and try the command again. If the message still appears, your system does not have enough
memory to process the command.
