Search the archives how?  The search engine on the NetBSD web site has
never been able to find anything the few times I've tried. 

Anyway, I was able to use my new 1542CP with the stock 1.0_BETA kernel
by turning off most of the "enhancements" listed under the Advanced Options
in the SCSIselect utility (and turning the Plug and Pray idiocy off).  This
may not apply to 1.1 or later, but it's probably worth a try and a lot easier
than trying to build a new kernel without a system.

P.S.  Beware of improper seating of long ISA cards.  The cost of error can
be high.
