## Thinkpad P53
My personal setup for the Thinkpad P53
## Hardware
- **CPU**: Intel® Core™ i9-9980H Processor
- **GPU**: NVIDIA Quadro RTX 4000
- **RAM**: 2x 16GB Samsung DDR4-2666 (M471A2K43DB1-CTD) + 2x Micron 32GB DDR4-3200 (MTA16ATF4G64HZ-3G2E2)
- **Drive 0**: Micron 3500 1TB (MTFDKBA1T0TGD-1BK1AABYYR)
- **Drive 1**: Micron 3500 1TB (MTFDKBA1T0TGD-1BK1AABYYR)
- **Drive 2**: Micron 3500 1TB (MTFDKBA1T0TGD-1BK1AABYYR)
**Notes**:
As of this writing, the Micron 2500, 2650, and 3500 are the only client SSDs advertising [firmware verification](https://www.micron.com/content/dam/micron/global/public/documents/products/product-flyer/micron-ssd-secure-foundation-flyer.pdf). I am not sure how secure the implementation is, but I guess it is better than nothing.
There are other enterprise SSDs from Micron with firmware verification, but I am not using them here due to heat and power constraints.
Unlike the likes of WD and Samsung who make life extremely difficult unless you buy an OEM drive, Micron [provides firmware updates on their website and also includes an update utility for Linux](https://www.micron.com/products/storage/ssd/micron-ssd-firmware#accordion-e6c186b05b-item-2ebc81f38a). There is no need to look for the Dell or Lenovo version of a drive to get updates via LVFS.

## Legacy boot workaround
Check [this issue](https://github.com/QubesOS/qubes-issues/issues/8732).
This is the `/etc/grub.d/42_custom` file I use for Qubes 4.2.3:
```
#!/usr/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.

## Partitioning
Drive 0 stores the host OS and less important VMs. Drive 1 and 2 run in btrfs RAID 1 and store VMs where redundancy is required. All drives will be encrypted with LUKS, and BTRFS checksum with Blake2b will provide integrity checking.
Open the shell with Control + Alt + F2 to get to the tty.
Do `ls /dev/disk/by-id` to check the serial numbers and find the correct drive. Anaconda, for whatever reason, may have different drive numbering than your firmware.
```
fdisk /dev/nvme0n1
d [Delete all the partition]
n
p
[Enter]
[Enter]
+1G
[If asked to remove signature, Y]
n
p
[Enter]
[Enter]
[Enter]
[If asked to remove signature, Y]
w
cryptsetup luksFormat /dev/nvme0n1p2
YES
cryptsetup open /dev/nvme0n1p2 cryptroot
mkfs.btrfs --csum blake2b -L qubes_dom0 /dev/mapper/cryptroot
cryptsetup close /dev/mapper/cryptroot
```
Use Control + Alt + F6 to get back to Anaconda.
Install destination -> Choose the drive -> Advanced Custom (Blivet-GUI) -> Hit refresh at the bottom right -> Rescan Disks -> Done
Format the first partition as ext4, mountpoint /boot
Unlock the second partition
Btrfs subvolumes -> create new -> name root, mountpoint /
Finish the rest of the installation as normal.
## Post install
### BTRFS optimizations
Edit /etc/fstab and add the following options for the / mountpoint:
```
ssd,noatime,compress=zstd
```
Reboot to apply the optimizations.
### xen-pciback.hide
Add this to the Linux karg:
```
xen-pciback.hide=(01:00.0)(01:00.1)(01:00.2)(01:00.3)(00:14.0)(00:1f.6)(2c:00.0)(54:00.0)
```
