Hi,
I cleared the CMOS RAM of the "broken" mobo, removed the RME and
TerraTec sound cards and unplugged the DVDRAM from the PSU and mobo,
now everything works, I just needed to rewrite a script to use enp2s0
instead of enp3s0.
After just clearing the CMOS RAM, without removing hardware, I got back
the start beep, that was missing before, but there was no monitor
signal. Perhaps I was impatient and didn't wait long enough and
removing the devices wasn't needed. Anyway, after booting worked
without the devices I mounted the RME sound card, but not the TerraTec
sound cards and reconnected the DVDRAM, enp2s0 became enp3s0, my script
now gets the device name by
$(basename $(ls -d /sys/class/net/enp?s0)) ;).
Excepted of shielding issues for the RME card, especially when loading
a YouTube video there's nice parasitic noise, everything still is fine.
The parasitic noise seems to be a little bit louder now, but the fans
seems to be more silent then before.
The only problem is, that the start from BIOS to GRUB is slow, but not
dramatically slow, startup from GRUB to Linux still is quick, but I
didn't restore all old BIOS settings, perhaps that does cause the
slowness.
Today I can't continue trouble shooting.
I still want to buy a new mobo, but assumed the issue with the old mobo
is fixed, then I wont order a new mobo this year.
iPad browsers and the iPad MUA are a PITA, nice to have the Linux PC
back at the moment.
Regards,
Ralf
