## 5.Code

It is advisable to modify the code if you have the programming ability, otherwise it may lead to unforeseen failures.

If you only want to display this keyboard in the vial settings interface, you can use the file below.

The vial.json file below only contains the layout for if-alice. Simply replace it with the original one in the if\_rec folder.

It is recommended to first download the vial client version 7.5, then set the button to enter the flashing mode and trigger it.\
Old version of vial client - Quantum - Reset\
The new version of the vial client - Quantum - Bootloader\
After triggering, a "IFKB" disk will appear on the computer. Simply copy and paste the uf2 firmware into it, and the hardware will automatically program it and then disconnect from the computer.

In the case of normal keyboard use, set a Reset key (Quantum->Reset) on VIAL, and then trigger the switch at that position. A disk named "IFKB" will appear on the computer, and the uf2 file will be copied to the disk. When the copy is complete, the disk automatically disappears and the receiver automatically reconnects to the computer. If there is a failure in this process, you can repeat the operation. We also set a CLR\_EE keycode (User->CLR\_EE), which is recommended to be set to the keyboard after updating the firmware, and trigger it once, and the keyboard will clear the settings.

## 5.Code

It is advisable to modify the code if you have the programming ability, otherwise it may lead to unforeseen failures.

{% hint style="info" %}
**Updated on December 31, 2025**
{% endhint %}

1.Install QMK CLI 1.2.0
\
2.Clone the vial-qmk repo and checkout the correct commit (fcd56b119ea8c60142c9a03e997be5a7acba52b7)

Below is the source code for the keyboard.

{% file src="/files/fOchrwn0HOIZmX6imWbR" %}

The uf2 file is already compiled.

{% file src="/files/kEZv5XaDlgOBuuGQlOkm" %}

If you only want to display this keyboard in the vial settings interface, you can use the file below.

{% file src="/files/EEQcCmJakJzYg0MM90la" %}

The vial.json file below only contains the layout for if-ergolite. Simply replace it with the original one in the if\_rec folder.

{% file src="/files/Hfwj6OORuIBIzFOq49sI" %}

It is recommended to first download the vial client version 7.5, then set the button to enter the flashing mode and trigger it.\
Old version of vial client - Quantum - Reset\
The new version of the vial client - Quantum - Bootloader\
After triggering, a "IFKB" disk will appear on the computer. Simply copy and paste the uf2 firmware into it, and the hardware will automatically program it and then disconnect from the computer.

{% hint style="info" %}
The stable version of Old
{% endhint %}

1.Install QMK CLI 1.1.2
\
2.Clone the vial-qmk repo and checkout the correct commit (601fc4b20a)

{% file src="/files/QAf37FZwtr3vxX5iIg4Q" %}

{% file src="/files/tRDNir0SZEb0VEkvaHdk" %}

In the case of normal keyboard use, set a Reset key (Quantum->Reset) on VIAL, and then trigger the switch at that position. A disk named "IFKB" will appear on the computer, and the uf2 file will be copied to the disk. When the copy is complete, the disk automatically disappears and the receiver automatically reconnects to the computer. If there is a failure in this process, you can repeat the operation. We also set a CLR\_EE keycode (User->CLR\_EE), which is recommended to be set to the keyboard after updating the firmware, and trigger it once, and the keyboard will clear the settings.


# Installation manual

## 1.Hot plug

<figure><img src="https://385242154-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnKEYHvvdjyFhBokhnRcl%2Fuploads%2FjVXz4lKuCsSpXO8TLilp%2F0171J%25~GW%5B6~~%5D%25O%254H1B1V.png?alt=media&amp;token=3318f5a1-1bd8-4513-9c72-9c1595d8be83" alt=""><figcaption></figcaption></figure>

The upper shaft seat is a Gateron low-profile shaft seat.

The lower shaft seat is an MX shaft seat.

These two types of shaft seats are not compatible with each other. Please avoid using force or engaging in violent operations.

## 2.Installation process

**First, install the switches onto the positioning plate, and then install the entire positioning plate onto the PCB.**&#x20;

\*The positioning plate and the PCB are fixed only through the switches, without screws or studs. (This keyboard is mainly designed for low-profile shafts, and the height from the low-profile shaft positioning plate to the PCB is too small to use screws.)&#x20;

\*Small tip for installing low-profile shafts: Pay attention to the latch of the switch, which is located on both sides. When installing, first insert the side with the latch into the positioning plate, and then use your fingernail to push the latch on the other side, and it will easily slide in.
