Interesting. The other fix for the upcoming ArcaOS refresh is that the missing SCSI driver AICU320.ADD will be included.
Unfortunately, the one that apparently affects mainly AMD installations won't be considered by the refresh: ACPI.PSD needs (sometimes?) the /VW option to continue the installation. BTW: The same applies to eCS. (When that can't be determined automatically by the driver, it should be made an option in the installer. Bug report follows later.)
(I have to thank several people who posted their AMD problems in the bug tracker or here while I was in vacation. That has saved me a lot of trouble.)
