Back to the A2410, this time with Amix. (Figured I may as well post here rather than make a new thread.)
In Amix the A2410 mouse cursor is all white.
Testing with the hardfile from
this post by vintageBytes. The link to amix_hardfile.7z no longer works, but the file is available via web.archive.org (go there and enter the URL from the post).
After booting the HDF, log in as root then do either "xinit -- -tiga -tm 3" or "olinit -- -tiga -tm 3"
