Bootloader configuration

The bootloader can be configured via 'bootloader/hekate_ipl.ini' (if it is present on the SD card). Each ini section represents a boot entry, except for the special section 'config' that controls the global configuration.

There are four possible type of entries. "[ ]": Boot entry, "{ }": Caption, "#": Comment, "newline": .ini cosmetic newline.

Configuration keys/values when boot entry is config:

Config option Description
autoboot=0 0: Disable, #: Boot entry number to auto boot.
bootwait=3 0: Disable (Having VOL- pressed since injection goes to menu. It also disables bootlogo.), #: Time to wait for VOL- to enter menu.
customlogo=0 0: Use default hekate bootlogo, 1: Use bootlogo.bmp.
verification=2 0: Disable Backup/Restore verification, 1: Sparse (block based, fast and not 100% reliable), 2: Full (sha256 based, slow and 100% reliable).

Possible boot entry key/value combinations:

Config option Description
logopath={SD path} If global customlogo is 1 and logopath empty, bootlogo.bmp will be used. If logopath exists, it will load the specified bitmap.
warmboot={SD path} Replaces the warmboot binary
secmon={SD path} Replaces the security monitor binary
kernel={SD path} Replaces the kernel binary
kip1={SD path} Replaces/Adds kernel initial process. Multiple can be set.
kip1patch=patchname Enables a kip1 patch. Specify with multiple lines and/or as CSV. Implemented patches right now are nosigchk,nogc
fullsvcperm=1 Disables SVC verification
debugmode=1 Enables Debug mode
atmosphere=1 Enables Atmosphère patching
payload={SD path} Payload launching. Tools, Linux, CFW bootloaders, etc.
