Hi!

Stupid question of the week: Is it absolutely necessary to run ecu if I 
add an Adaptec 2740T (EISA) card into an Alphastation 600 ? 

I added the card, ran ecu (1.11A) and it didn't find the card (ADP7771 or
similar). So I googled around and found some files that looked promising:
ADP7770 and !ADP7771. Ran ecu again, everything seemed to go fine but
apparently the CFG-file wants to include an *OVL file and ecu didn't like
that.

On boot it complains:
EISA configuration error detected!

When trying the latest and greatest current I run to this:

eisa0 at pceb0
ahc1 at eisa0 slot 3: Adaptec AHA-274x SCSI
ahc1: edge triggered interrupting at isa irq 15 
ahc1: aic7770 >= Rev E, ahc1: Host Adapter Bios disabled.  Using default SCSI ds

ahc1:SCB 0x3f - timed out 

The timeouts are coming from scsibus3 & 4, 1 & 2 are empty and the ahc1 (ie.
the EISA card) only has a TLZ06 DDS drive. scsibus0 has one drive. Don't
ask.

Before I start spamming more heavily (card state dumps :-) should the ecu
configuration go smoothly before I tackle NetBSD ?

Help out an EISA newbie :-)
