In the future it will be used for far more.

Hekate now has a new storage in the binary that helps it configure it outside of BPMP enviroment:
| Offset / Name | Description |

| '0x94' boot_cfg | bit0: Force AutoBoot, bit1: Show launch log. |
| '0x98' autoboot | If `Force AutoBoot`: 0: Force go to menu, else boot that entry. |
| '0x9C' autoboot_list | If `Force AutoBoot` and `autoboot` then it boots from ini folder. |
| '0xA0' rsvd_cfg | Reserved. |
| '0xA4' rsvd[32] | Reserved. |
You can find a template [Here](./res/hekate_ipl_template.ini)
If the main .ini is not found, it is created on the first hekate boot.
