====== Boot Codes Explained ======

Boot codes are configuration options. An examples is "tce=sda1," which indicates the location of the tce directory.

==== CD or Installed ====

When running from a CD, include "tinycore" before bootcodes. Following is an example.

If Tiny Core is installed, include

<code>tce=sda1</code>

in the bootloader.

If running from a CD, use

<code>tinycore tce=sda1</code>

==== Bootloader Examples ====

Below is a boot stanza from a syslinux configuration file:

<code>label tinycore
kernel /tce/bzImage
append initrd=/tce/tinycore.gz quiet waitusb=5 tce=UUID="F0BC-3CAF" tz=EST,M10.1.0/2,M4.1.0/2</code>

Below is the boot stanza from a grub menu.list file:

<code>title tinycore
root (hd1,0)
kernel /tce/bzImage quiet waitusb=5 tce=UUID="F0BC-3CAF" tz=EST,M10.1.0/2,M4.1.0/2 
initrd /tce/tinycore.gz</code>

Note that the boot codes are on different lines for the 2 cases. In each case one line has the boot codes <code>quiet waitusb=5 tce=UUID="F0BC-3CAF" tz=EST,M10.1.0/2,M4.1.0/2</code>

These mean:
  * ''quiet'': don't display all boot messages
  * ''waitusb=5'': Wait 5 seconds for the file system to be mounted when booting from the usb device
  * ''tce=UUID="F0BC-3CAF"'' is the same as ''tce=sdb1'', but ''sdb1'' depends on what other disk devices are connected so ''sdb1'' may not always be the case. The UUID eliminates this problem because it uniquely identifies the device regardless of what other devices are connected.
  * ''tz=EST,M10.1.0/2,M4.1.0/2'': time zone information with daylight saving info (Month 10, week 1, day 0, 2am).

==== More Examples ====

To boot from CD, utterly ignoring any perfectly valid TC install which may or may not be otherwise present

<code>tinycore base norestore</code>

To boot entirely irrelevant of the automatic backup/restore style of persistence based on the list of files in ''/opt/.filetool.lst''

<code>tinycore norestore</code>

To boot irrelevant of automatic backup/restore persistence, but fully relevant of the rest of the persistence options, with a prepared and usable hard drive partition at ''/dev/sda1''

<code>tinycore norestore tce=sda1 opt=sda1 home=sda1</code>

To boot maintaining automatic backup/restore persistence, but fully relevant of the rest, with hard drive partition at /dev/sda1, USB wait of 5 seconds, and hostname preset to TCABCD

<code>tinycore waitusb=5 host=TCABCD tce=sda1 opt=sda1 home=sda1</code>

a update as of '[[http://forum.tinycorelinux.net/index.php/topic,12836.0.html|Core 4.4]]' add's 

"New boot code, e.g., iso=sdb1 booting from a single ISO file to load embedded extensions."
and 

"* New fromISOfile script for after boot support of a single ISO file embedded extensions."
