You cannot install RedHat Linux 6.0 on a ICP Vortex (GDT)
only system because there is no gdth module on the Bootdisk.
(I created a gdth module but the installer refuses to load
it because of a bad magic of the cpio module archive..)
The gdth module is present, but appears to not work.
It is called the "ICP Disk Array Controller"
The ICP Raid Controller is listed but the correct module is not
included on the installer disk or media. We are working to make un
updated installer which will be released as soon as possible.
I added the gdth.o module to the modules.cgz archiv in
i386/RedHat/instimage/modules then I can Install my System with NFS
method. But after the first boot it's unable to mount the root fs on
the raid array becuase the gdth.o module wasn't found. So I'm giving
this was fixed with the errata bootdisk, AFAIR.
