ran opensuse installation dvd
no hard drive found
tried several kernel modules in linuxrc
no harddrive found
i have 2 sata drives and via chipset vt8237
i had even problems with windows getting my second hard drive running, because driver is hard to find an installs with problems.
i think the windows driver writes into flash memory of the chip because it changes appearance in bios setup. maybe new installation of driver may help but i fear afterwards the controller is crashed (never change a running system ?).
every 5 years i try to install linux,
then those hardware problems come, and i do not come to a working installation.
maybe someone has a simple solution, or i will come back in 5 years.
