General Comments

Sigurd tested this Thinkpad with ArcaOS 5.0.4. His comments are:

  • The usual settings in the BIOS (Secureboot off, Legacy Boot on, USB 3.0 Disabled).
  • The installation of the USB stick ran without significant problems, the SSD was completed wiped.
  • WINOS2 started after installation of the additional package (viop-1.0.wpi from the bugtracker) as desired.
  • Uniaud works with unimix. Check the trick below.
  • ArcaOS USB drivers needed to be replaced with those from Lars Erdmann, as ArcaOS's drivers do not support Isyncronus Data Transfer, wich is needed for Touch screen, Stylus and Webcam.

Audio

The Uniaud.sys driver works with the / A: 1 switch Unimix is also required and you need to the add the following on the Startup.cmd:

unimix -id1 -val74 -cnt0
unimix -id1 -val74 -cnt1
unimix -id2 -val1 -cnt0
unimix -id2 -val1 -cnt1
exit
