my cheatcodes.txt says this:

The cheatcodes listed here are only those
that are specific to Porteus (see the final note for information on
cheatcodes that apply to all linux distributions, including Porteus).

and at the end as mentioned we find this

The cheatcodes listed above are those that are unique to Porteus.
There are literally hundreds of other kernel boot parameters
that can be used. For more information on these parameters visit:
http://www.kernel.org/doc/Documentation ... meters.txt

but that's a 404:

web.archive.org to the rescue, there are 348 captures (24 Feb 2008 - 6 Oct 2022) for https://www.kernel.org/doc/Documentatio ... meters.txt
Cave! The newer ones are all 404 as well.

Therefore I choose an older one quite randomly:
https://web.archive.org/web/20140908094 ... meters.txt

To get the text only version use this URL:
https://web.archive.org/web/20140908094 ... meters.txt

e.g. with wget:

HTH.

[ncmprhnsbl]

new place looks to be: https://www.kernel.org/doc/Documentatio ... meters.txt
which is where /usr/doc/cheatcodes.txt has it ...seems that change didn't percolate through to /boot/docs..

[Ed_P]

my cheatcodes.txt says this

Where do you find this file?

which is where /usr/doc/cheatcodes.txt has it

I found it. It's in /usr/doc/porteus/cheatcodes.txt.

And here searched in the official XFCE 5.0 iso and in /usr/doc/porteus/cheatcodes.txt :

Code: Select all

root@porteus:/# mloop /mybin/linux/porteus/5.0/x86-64/ISO/Porteus-XFCE-v5.0-x86_64.iso 
using /dev/loop11
[…]

root@porteus:/# grep kernel-parameters.txt /mnt/loop/boot/docs/cheatcodes.txt /usr/doc/porteus/cheatcodes.txt 
/mnt/loop/boot/docs/cheatcodes.txt:http://www.kernel.org/doc/Documentation/kernel-parameters.txt
/usr/doc/porteus/cheatcodes.txt:https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt

It indeed did not percolate.

At least there is only one more difference, but that one might cause issues:

Code: Select all

root@porteus:/# diff /mnt/loop/boot/docs/cheatcodes.txt /usr/doc/porteus/cheatcodes.txt 
402c402
<        the value specified (0-100).  You will be able to raise

No, it won't, volume=0 is still valid as grep -C 3 tells us

Code: Select all

root@porteus:/# grep -C 3 "the value specified (1" /usr/doc/porteus/cheatcodes.txt
volume=some_value

   ... This parameter sets the system's Master Volume channel to
       the value specified (1-100).  You will be able to raise
       or lower the volume after you boot up as normal.
       The default value is 45.
       Example: 'volume=0' will boot into your chosen GUI silently.

And in case someone was curious, there is quiete the difference between my older now renamed into kernel-parameters-OLD.txt and the most recent one under the different URL:

With a size difference that huge I do not do a diff.
