Setup script for BC250 on CachyOS
(However, the current script does aim to work across other arch distros and the grub bootloader, but has not been tested yet.)

Disclaimer:  I am not responsible for any damages caused by use of this script.  Please review it to make sure the overclocking configs are compatible with your board. Unlocking compute units will increase power draw and heat.  You are responsible for your own power and cooling setups.  Misuse of this script could cause physical damage to your board.

### **Must be using Limine boot loader for all functions in the script to work.**  (Grub support has been added, but needs testing.)

This script will allow easy setup of the BC-250 on CachyOS.  It has been tested with the handheld edition, but should also work on any CachyOs version as long as the Limine bootloader is used.  Inspired by the similar script for Bazzite:  https://github.com/NexGen-3D-Printing/SteamMachine

It does the following:
1. Install CPU governor: https://github.com/bc250-collective/bc250_smu_oc/
2. Install GPU governor: https://github.com/filippor/cyan-skillfish-governor
3. Enable swap
4. Hide the RDSEED error displayed on boot.
5. Enable ZSWAP
6. Easily change CPU and GPU overclock settings on the fly
7. Displays a status window showing you your current settings.
8. Unlock compute units thanks to: https://github.com/WinnieLV/bc250-cu-live-manager
9. Set vram split and ttm pages: https://github.com/fanoush/bc250_memcfg
10. Unlock CPU Cores: https://github.com/rw-r-r-0644/bc250-core-unlock , https://github.com/Hexxeh/bc250-efi-core-unlock
11. Install ACPI Fix: https://github.com/mendesrr/bc250-acpi-fix-updated-8c
12. Install custom BC-250 kernel: https://github.com/MastaG/linux-cachyos-bc250

In desktop mode run the below in the terminal(Konsole):
<pre>
curl -sSLO https://raw.githubusercontent.com/redbeard1083/bc250-toolkit/main/bc250-toolkit.sh && chmod +x bc250-toolkit.sh && ./bc250-toolkit.sh
</pre>
As it is a frequently asked question, to re-run the script after running it the first time:
<pre>
./bc250-toolkit.sh
</pre>

```
