Accessibility
The appearance of the BIOS Setup Utility is simple and uses contrasting colours, so it may work well with OCR software. A legend of keyboard navigation shortcuts is also clearly listed at the bottom right of the screen.
Note
Blind users should request the help of a sighted person to change BIOS settings. There are no Keyboard beeps in the BIOS Setup Utility.

Installation
To enter the firmware set-up, press
Fn+F2
(or maybe only
F2
) repeatedly at boot.  
For the boot menu, use
Fn+F7
.
Disable
Secure Boot
in the security section before installing, then save and restart to the boot menu and select your installation device.
Pen and tablet mode
The Hi10 Max stylus conflicts with the
ilitek_ts_i2c
touchscreen driver.  
By default, when the driver is loaded, tablet mode detection works, but the stylus does not.
To enable stylus support, blacklist the module:
/etc/modprobe.d/blacklist-ilitek_ts_i2c.conf
blacklist ilitek_ts_i2c
However, this disables tablet-mode detection. To restore it, install the
chuwi-hi10-max-tablet-mode-dkms-git
AUR
package, which provides keyboard-based mode switching.
It hard-codes the id of the keyboard. If you happen to have a different id, open a bug report in
https://github.com/aligator/tablet-mode
Screen rotation
In tablet mode, the accelerometer reports an incorrect orientation.
To fix it,
create
the file:
/etc/udev/hwdb.d/61-sensor-local.hwdb
sensor:modalias:*
 ACCEL_MOUNT_MATRIX=1, 0, 0; 0, 1, 0; 0, 0, 1
Then
update the hardware database index
.
libwacom configuration
When the screen is rotated, the stylus may not apply the rotation, to fix this, create a custom device description:
/etc/libwacom/chuwi-hi10max.tablet
# CHUWI Hi10 Max Stylus

[Device]
Name=Chuwi Hi10 Max Stylus
DeviceMatch=i2c:222a:0001
Class=ISDV4
Width=9
Height=6
IntegratedIn=Display;System;
Styli=@generic-no-eraser

[Features]
Stylus=true
Touch=false
After that, reboot.
It may be needed to calibrate the pen again in your desktop environment settings.
For gnome this may be the correct calibration:
$ dconf write /org/gnome/desktop/peripherals/tablets/222a:0001/area "[0.0024305731058120728, -0.060763880610466003, -1.4901161193847656e-08, -7.4505805969238281e-08]"
Secure Boot
Follow
Secure Boot
set-up using
sbctl
.
If you have installed the custom module from the  tablet mode workaround, you have to enable automatic DKMS module signing with sbctl keys.
/etc/dkms/framework.conf
sign_file="/usr/lib/modules/$kernelver/build/scripts/sign-file"
mok_signing_key="/var/lib/sbctl/keys/db/db.key"
mok_certificate="/var/lib/sbctl/keys/db/db.pem"
Rebuild the module (e.g. by reinstalling it) to sign automatically.
USB-C charging
Note that the tablet does not charge with all chargers as it seems to require 12V and does not work with for example 20V chargers.
Also note that the delivered charger may be dangerous with other devices
