boot2 is the first non-built-in sysmodule. It's presumably hardcoded to be the first sysmodule launched by PM.

boot2 is the first non-built-in sysmodule. It's hardcoded to be the first sysmodule launched by PM.
   −
It connects to "pm:shell" service and launches the following titles in this order:
+
On retail systems, the boot2 title is called [[#boot2.prodBoot|boot2.prodBoot]] while on debug systems it's called [[#boot2|boot2]]. Debug systems also have a version called [[#boot2.SafeMode|boot2.SafeMode]] installed in SAFE for safe mode. During [[Factory Setup|the factory setup process]] the boot2 title is called [[#boot2.manuBoot|boot2.manuBoot]] instead.
 +

= boot2.prodBoot =
 +
It opens the [[Process_Manager_services#pm:shell|pm:shell]] service and prior to [[10.0.0|10.0.0]] launches the following titles in order:

   −
Then it connects to "set:sys" and reads a bool from "boot" section called "force_maintenance" with default value true.
+
It then opens the [[Settings_services#set:sys|set:sys]] service and reads a bool from the "boot" section called "force_maintenance" with default value set to "true".
 +
 
 +
If the value reads successfully as "false", it opens the [[Bus_services#gpio|gpio]] service and opens sessions for GPIOs 26 and 25.
 +
If both GPIOs read as zero, then [[Recovery_Mode|maintenance mode]] is forced despite the setting being false. This checks if both volume up and down keys are held down at the same time.
   −
If the value reads successfully as false, it initializes "gpio" and opens sessions for GPIOs 26 and 25.
+
If it's in maintenance mode then it opens the [[Process_Manager_services#pm:bm|pm:bm]] service and calls [[Process_Manager_services#pm:bm|SetMaintenanceBoot]].
−
If both GPIOs read as zero, then maintenance mode is forced. This probably checks if both volume up and down keys are held down at the same time?
     −
Then depending on maintenance mode or not it launches the following titles in this order:

This list is probably optimized for boot-time. It launches display-related things first presumably to make sure it displays something as soon as possible.

If the "boot!use_htc_gen2" setting is set to "true", htc and dmnt.gen2 are used, otherwise tma and dmnt are used (Note: htc and dmnt.gen2 are not currently present in recovery mode).

After launching all titles, it'll check the "boot!boot_devmenuapp_installer" setting and attempt to launch 01000000000020f0 (devmenuapp_installer) if it's set to true.

Just like [[#boot2.prodBoot|boot2.prodBoot]], it opens the [[Process_Manager_services#pm:shell|pm:shell]] service and launches the following titles in order:

Otherwise, it launches exactly the same titles as [[#boot2.prodBoot|boot2.prodBoot]] in the same order, but then finishes by launching 010000000000B14A ([[Manu Services|Manu]]) before exiting itself.
 +
 +
After launching all titles, it'll check the "boot!boot_devmenuapp_installer" setting and attempt to launch 01000000000020f0 (devmenuapp_installer) if it's set to true.
 +
 +
= boot2.Manu1st =

As of version [[2.1.0|2.1.0]], just like [[#boot2.prodBoot|boot2.prodBoot]], it opens the [[Process_Manager_services#pm:shell|pm:shell]] service and launches the following titles in order:
 +
* 0100000000000021 (psc)
 +
* 0100000000000009 (settings)

 +
At this point it checks if the device is being booted in maintenance mode, if it is it opens the [[Process_Manager_services#pm:bm|pm:bm]] service and calls [[Process_Manager_services#pm:bm|SetMaintenanceBoot]] then attempts to to launch titles in the same order that [[#boot2.ManuBoot|boot2.ManuBoot]] does in maintenance mode.
 +
 +
Then it attempts to launch the following titles in the following order:
 +
* 010000000000001F (ns)
 +
* 0100000000000015 (lm)
 +
* 0100000000000034 (fatal)
 +
* 010000000000B14A (manu)
 +
 +
After launching these processes, it exits.
 +
 +
= boot2.FromHost =
 +
Just like [[#boot2.prodBoot|boot2.prodBoot]], it opens the [[Process_Manager_services#pm:shell|pm:shell]] service and launches the following titles in order:
 +
* 0100000000000021 (psc)
 +
* 0100000000000009 (settings)
 +
* 0100000000000006 (usb)

 +
* 010000000000001A (pcv)
 +
 +
After launching these processes it'll attempt to load a list of process to launch off the host device.
 +
 +
First it checks if a "SIGLO_BOOT_LIST_DIR" environmental variable is present on the host device, if it is, it loads the list from "NX-NXFP2-a64.txt" from the directory specified in "SIGLO_BOOT_LIST_DIR".
 +
 +
If that fails, it checks if a "SIGLO_BOOT_LIST_PATH" environmental variable is present on the host device, if it is, it loads the list from the path specified by "SIGLO_BOOT_LIST_PATH".
 +
 +
If that also fails, it defaults to loading "C:/siglo_boot/list.txt" from the host PC.
