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.
Global 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 (It also disables bootlogo. Having VOL- pressed since injection goes to menu.), #: Time to wait for VOL- to enter menu. |
verification=2 | 0: Disable Backup/Restore verification, 1: Sparse (block based, fast and not 100% reliable), 2: Full (sha256 based, slow and 100% reliable). |
autohosoff=1 | 0: Disable, 1: If woke up from HOS via an RTC alarm, shows logo, then powers off completely, 2: No logo, immediately powers off. |
autonogc=1 | 0: Disable, 1: Automatically applies nogc patch if unburnt fuses found and a >= 4.0.0 HOS is booted. |
backlight=100 | Screen backlight level. 0-255. |
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. |

kernel={SD path} | Replaces the kernel binary |
kip1={SD path} | Replaces/Adds kernel initial process. Multiple can be set. |
