Hi bud, the TPU gaskets are not needed anymore, they were very early versions, everything required is now on Printables, this is how you install the fan mount: https://www.youtube.com/watch?v=E-utAYMynzc
BIOS Flashing and setup information is here: BIOS Flashing Guide - AMD BC250 Documentation
Use V3 BIOS not V5.
For setting up Bazzite on the BC-250, just install like you would for any other PC, then once its up and running, use my script to install GPU overclocking, ram fixes and other tweaks: GitHub - NexGen-3D-Printing/SteamMachine: Information and fixes for my DIY Steam Machine using the BC-250
After thats done, then install the ACPI tables so the power modes work correctly:
git clone GitHub - bc250-collective/bc250-acpi-fix: Fix bc250's acpi table
cd bc250-acpi-fix
mkdir -p /tmp/acpi_tables/kernel/firmware/acpi
cp *.aml /tmp/acpi_tables/kernel/firmware/acpi/.
cd /tmp/acpi_tables
find kernel | cpio -H newc --create > SSDT_ACPI.cpio
sudo cp SSDT_ACPI.cpio /boot/.
echo ‘GRUB_EARLY_INITRD_LINUX_CUSTOM=“../../SSDT_ACPI.cpio”’ | sudo tee -a /etc/default/grub
ujust regenerate-grub
systemctl reboot
After thats completed, you can install CPU over clocking:
rpm-ostree install stress
git clone GitHub - bc250-collective/bc250_smu_oc: CPU Overclocking Tools for AMD BC-250
cd bc250_smu_oc
pip install .
My recommend CPU OC/UV settings: bc250-detect --frequency 3850 --vid 1135 --temp 80 --keep

Hopefully that answers all your questions.
