[comp.sys.amiga.hardware] Problem with ICD AdSCSI 2080 Card

yclept@cs.mcgill.ca (George FOSTER) (05/17/91)

I recently bought this card with 4 megs of RAM installed. It works fine
in my 2000 with a Quantum 80S hard drive, but only if I disable the RAM 
(via a couple of jumpers on the card). With the RAM enabled, the 2000
won't boot--the screen just cycles colours while the power light winks.

I've tried re-seating the SIMMs, swapping them, using only 2 megs, and
every reasonable combination of jumper settings, to no avail. Should I
just return the card, or is there something I'm missing? Thanks for any
help. (In case it's pertinent, I'm using WB 1.3 with 1.3 Kickstart ROMs).

Well, I don't know if this applies to your particular problem but I had the 
same problems when I upgraded to a GVP Series II HC+8.  My simms worked fine 
in my 8-up board and would work in my GVP card in my dealers machine but 
not in my A-2000.  After several days of swapping simms I finally got 
through to GVP's tech department.  There is a jumper on the GVP's that must
be set to allow the memory to work correctly with older motherboards (rev 4.x).
This was not mentioned anywhere in the manual and my dealer wanted me to 
take my system in for a motherboard upgrade (past service with this dealer 
indicated that this would have take about 3 months for them to add a couple
of resistors :-( ).  After setting the jumper, the GVP and memory has been 
working just fine (and all without the motherboard upgrade :-).

hope this helps....
