I tried setting the CMOS to Bi-Directional as suggested to no avail.
I also tried to force the mode but I am not sure that I did that correctly.
Using the RedHat 5.0 installation I specified -mode 1 on the additional
options line prior to the installation locating the drive. This did not work
either.
Is this the correct way to set the mode? Are there any other things I
should try?
Thanks
