Look for knoppix-cheatcodes.txt on any Knoppix CD or DVD.
Or, if using a Knoppix Live System, at
/home/knoppix/Desktop/KNOPPIX/KNOPPIX/knoppix-cheatcodes.txt or
/mount-system/KNOPPIX/knoppix-cheatcodes.txt
Could I be directed to a post(s) which discusses the codes that could be passed on to knoppix during boot time via knoppix-data.inf?
Thanks.

Dear Utu,
I am surprised! Does this mean that the entire cheat-code can be written "AS ARE" within the file knoppix-data.inf ?
When I had Debian system with Grub I used to pass the cheat-codes in grub.cfg to Knoppix in order to boot from that image.
Please direct me to the documentation section where the knoppix-data.inf is discussed, particularly passing the cheat-codes to knoppix during boot time.
I am surprised because I had tried knoppix nodrm nofb 2 in knoppix-data.inf . But the codes were ignored.
I suppose there has been a misunderstanding about your question. Within 'knoppix-data.inf' there is of course only the information about the overlay partition (not overlay file). How to build this file you can see in '/usr/bin/flash-knoppix(2)'.
How Knoppix interprets this file during boot, you can see within the "init"-file of the minirt.gz in the function mountdata() and there starting at the line "inf) # Contain partition information ...".
For simplicity reason Knoppix only supports "overlay partition" on the 2nd partition with partitionname KNOPPIX-DATA and ReiserFS. If you want to change this behaviour, you have to do many hacks by yourself in this two scriptfiles.
@ Rajib
If one is using Knoppix as a LiveUSB, one may add or change cheatcodes at boot
by modifying APPEND statements in /mnt-system/syslinux.cfg.
If this is done before any persistent changes are recorded, I would expect that
to serve to apply to any cheatcodes you want.
Yes, Utu, so I found! I have been exploring the boot folder in mnt-system/boot/syslinux and tested and found the entered code to be working, across multiple booting. My first line looks as follows:
So now I have a working Knoppix running from pen-drive with a persistent ext4 partition whose data and files I can change from other computers.Code:DEFAULT knoppix APPEND lang=en apm=power-off initrd=minirt.gz nomce nofb nodrm tz=/Asia/Kolkata libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 TIMEOUT 20
Thank you, Utu. You always provide straight-forward reply.
PROBLEM SOLVED!

Yes, defragmentation of the RFS and corruption following multiple shutdowns. I have discussed this earlier: My HCL laptop is faulty, thanks to our cybercoolies. Its heat-dissipation system is faulty, leading it to high temperatures when the CPU cycles are 100% utilised.
And I also wish to use this last post from my end to thank Mr. Schulz, a very nice person, who tried to help me complete this project, stayed with me and provided inputs.
Dear Utu, I felt I needed to explain myself better.
Both ext4 and the reiser are Journaling Filesystems. To understand the intricacies which warrants implementation of Journals, one has to understand the read-write operations and a power failure during the system's writing data on a storage device, e.g., HDD.
Journaling is a separate area to store To-Be-Written data before writing. If power is cut off during writing from the journal to the permanent data area, we have the journal to recover our work. ext4 is the latest one, having the scope for a huge journal.
Linux doesn't implement Raiser with its full capabilities. Moreover, Knoppix-data.img is really Reiser upon another FS, i.e., journal upon journal, i.e., four (2^2) times the amount of read-write operations than when using a single FS.
My damaged laptop is the result of design by damaged minds. This was the reason for my implementing ext4 directly. I hope I have explained myself as clearly as I am capable of.

knoppix-data.img and knoppix-data.aes are special files within the Flash disk install of Knoppix (FAT32). These files are the overlay files and are ext2 formatted (encrypted or not).Knoppix-data.img is really Reiser upon another FS, i.e., journal upon journal,..
The overlay partition in a standard Flash disk install of Knoppix is the whole 2nd partition and is ReiserFS formatted. You can also check and fix ReiserFS with the tool "reiserfsck". Therefore I cannot see the need to use ext4 instead of ReiserFS.It's the Micro-Remastering as KK told us.I have been exploring the boot folder in mnt-system/boot/syslinux and tested and found the entered code to be working, across multiple booting.
