Hi,
You mean that the Hatari output and the Linux output are in a single file?
I would really appreciate to have two separate logs from the same boot
process, one with the Linux output only and the other with the
corresponding Hatari output only. All taken with the current Hatari
development version.
Best regards
Uwe
