tuning xmrig - disable secure boot - make sure that msr works

=====================================================
DISABLE SECURE BOOT - LENOVO THINKSTATION P330
=====================================================

1. ENTER BIOS
-------------
- Restart the PC
- Press F1 repeatedly right after power on
(before Linux boots)

2. NAVIGATE TO SECURE BOOT
---------------------------
- Go to: Security -> Secure Boot
- Set: Secure Boot = DISABLED

3. SAVE & EXIT
--------------
- Press F10 -> Yes -> Enter

4. BACK IN LINUX - LOAD MSR
----------------------------
sudo modprobe msr
echo "msr" | sudo tee /etc/modules-load.d/msr.conf
sudo ./xmrig

5. VERIFY IT WORKED
--------------------
Look for this line in xmrig output:

GOOD: msr set MSR 0x000001a4 to 0x000000000000000f
BAD: msr FAILED TO APPLY MSR MOD

=====================================================
EXPECTED HASHRATE AFTER FIX: ~3500+ H/s
(currently ~1593 H/s due to MSR being blocked)
=====================================================
