hi gerard-
ok, i built 2.2.5 with a minimal configuration, and it booted
successfullly. after weeding through the configuration options, the
problem option for me was SYMBIOS_COMPAT. when i disabled it, everything
worked perfectly. i'm not sure why the sym53c8xx driver wasn't working
earlier, but it seems to be now (2.2.12).
again, my hardware configuration is:
S450NX mainboard with Intel 82450NX PCIset
one ncr53c810a
two ncr53c896's
Symbios SCSI BIOS
one SCSI back-plane with 6 SCA connectors
thanks for steering me to the right conclusion.
