Qlogicfas driver failed to detect my scsi adapter, while it works fine in Debian

[zyu <zyu emory edu>]

hi, gurus...

I am trying to install RedHat 4.2 off the official CD sets. However, the
autoprobe failed to detect my SCSI-adapter. It is based on NCR-53c406a
chip. I tried to specify parameters for the "ncr53c406a" driver to
detect it, either failed to detect any or "abort due to timeout".  The
CD-rom drive is from Media Vision, with Sanyo the vendor.

I switched to Debian 1.3. It succesfully detected the SCSI adpater and
the CD-ROM (part of the log file attached). Sicne it is using Qlogicfas
0.45 driver, I switched back to Redhat trying to detect it again.
Failed.

Could any of you tell me why it failed, since it is the same driver?
Better, if you could tell me how to trick the installation to find my
SCSI.

Thanks a lot.

Jerry
