"Bad Number"

[Thomas]

This message comes from a command which requires a number as argument but got something else, for example a letter.

The cause is probably a typo, for example addbuffers df0: fifty instead of addbuffers df0: 50

Put set echo on as the very first command into your startup-sequence. It will then print every command to the shell before it executes it. With the help of this you can find out which command prints the message and correct it.

I am quite sure that AmiCDFS never asked you to replace existing system files with older versions. The supplied SetPatch is meant for early versions of AmigaOS (2.0 or something). If you already have a newer version you should not replace anything.
