Hi floppy
The purpose of cheat codes are to guide and in some cases overide the kernels default behaviour when
it is having problems booting with certain hardware configurations. If you give a cheat code that is not
appropiate for the hardware you are running you could slow it down or prevent it from booting. You
already state that the machine boots quickly and I assume it's running well, my advice would be don't
worry about cheat codes and enjoy using your computer. Having said that, be prepared to do a lot of
reading and searching on the internet. I use
http://www.mjmwired.net/kernel/Documentation because
they have all the documentation online in an easy to navigate format. This will come in handy since some
of the codes refer to other documents to help to describe how they work. A boot code will only work if it
that option has been compiled into the kernel. Add the code "printk.time=1" when you boot. When the
desktop comes up open a terminal and type "dmesg > dmesg.txt", this will create a file called dmesg.txt
that contains the startup and probing of the hardware complete with timestamps. Look through it to find
IF the kernel mentions any codes and if it is probing for any non-existant hardware (isa, pcmcia, etc.).
You can also find which items take the longest. Now search through the cheat codes to find the one's that
apply to you and be sure to read any documentation mentioned.
