KillCD0 (<- with a ZERO) is a small tool that can be used to kill CD0: on
a CDTV, A570 or CD32 so you can mount a new one with another filesystem
i.e. AmiCDFS or CacheCDFS from OS 3.9.


REQUIREMENTS:

OS 2.04 or better. And a CDTV, A570 or CD32! It is not very useful on a
1MB machine, but is should work!

A CDROM filesystem. AmiCDFS is on Aminet:
   amicdfs240.lha     disk/cdrom 133K 179+AmiCDFS (AmiCDROM) v2.40
If you have OS3.9 you can also use CacheCDFS. Other filesystems are not
tested but might work.

It is tested on:
An A500 with A570 and Harms-Turbo, 1MB chip & 8MB non-DMA fast, OS2.04,
OS2.1, OS3.0 and OS3.1.
A CD32 with SX-1, 2MB chip & 8MB fast, OS3.1 and OS3.9.


INSTALLATION:

Copy it to C:, that all.
Of course you must have a CD-FileSystem installed in L:!

If you use either AmiCDFS or CacheCDFS you can copy the appropriate CD0
Mountfile (the 'CD0' file, NOT the MountFile!) to your SYS:Storage
directory.
If you use OS2.04 append the appropriate MountFile to your Devs:MountFile.

Add to your user-startup the following:

--< snip >--
c:KillCD0 cd0
if not warn
  mount CD0:
endif
setenv cd0 $cd0
unset cd0
--< snip >--

Another way is to add the line 'c:KillCD0 cd0' early on in your startup-
sequence. Then below the line 'C:Mount >NIL: DEVS:DOSDrivers/~(#?.info)'
add the following:

--< snip >--
if $cd0 eq YES
  mount CD0:
endif
setenv cd0 $cd0
unset cd0
--< snip >--

Save the changes, reboot and see if is works.


USAGE:

The template is: KillCD0 VAR/A.

VAR is the name for the LOCAL variable used to save the result into. There
are three possible answers: 'YES', 'NO' and 'DISK'.

'YES'  : CD0: was killed.
'NO'   : CD0: was not killed.
'DISK' : CD0: was not killed because there is a disk in the drive.

Also RC is set to either 0 == success or 5 == no success!

If successful you can now mount another CD0: with another(=better)
filesystem.

I included mountfiles for CD0 using AmiCDFS 2.40 or CacheCDFS 42.19 from
OS3.9.


BUGS:

None that I know off.
