Title
While generating recovery diskettes, I get the error message "Kernel Still Too Large After Shrinkage"
Keywords
RecoverEDGE SCO kernel unix boot disk floppy OS 5
Product Release(s)
BackupEDGE 01.01.0X / RecoverEDGE 2 and SCO Unix Open Server 5 only
Problem Description
When I try to create recovery diskettes, I get the error message "Kernel Still Too Large After Shrinkage" or "Out of Space on dev(fd60)" My kernel is only 1.3 meg and should be capable of being condensed.

Cause
This problem occurs when running RecoverEDGE 2 on SCO Unix Open Server 5 systems.

A kernel size of 1.3 Mb happens to fall in a dead spot in the code in RecoverEDGE 2, RecoverEDGE 2 sees the kernel as already having been condensed and does not attempt to condense the kernel. Upon mount of the boot floppy, the kernel is then copied to floppy thus leaving no space for the boot program and various other files. A kernel larger than 1.3Mb does not have any problem.

Solution
While logged in as root, from the shell prompt type the following:

	  'compress -c -H /stand/unix >/kernel.edge'

This will copy /unix to another file which RecoverEDGE will use as an alternate kernel. Exit completely from the RecoverEDGE program and start a new RecoverEDGE session. Select Generate and make your floppies. You should see a message from RecoverEDGE stating that the alternative kernel kernel.edge is being used to create the diskettes.
