Greetings,


I am trying to set up a harddrive system for my Amiga 500, and I
am having some problems.

My hardware setup is as follows:

A500 with A501 memory expansion(total 1 Meg)
1 external floppy
Pacific Peripherals SubSystem 500
A2090 controller
Lapine LT2000 Harddisk in external case with power supply:
    ST506, 20 Meg, 65 Msec
    4 surfaces, 17 Bl/track, 615 cyl


While trying to get the system up, I am using the Workbench 1.3
disk right out of the box (a backup, that is!).  The version of
Prep on the 2090 software is 33.16.

When I power up the system (first subsystem, second harddisk, then
Amiga) the disk starts spinning and the heads start stepping until
the amiga prompts for the WB disk; at that time the harddisk stops
spinning.  It seems that when the amiga tries to communicate with 
the disk, the LED on the harddisk flashes.

Unfortunately, I don't have and technical info on the Lapine (I'm
going to see what I can get tomorrow).

Is anyone using a Lapine disk with a 2090?  Does anybody have any
idea what could be wrong?

When and if I get this problem taken care of,  how well will this
setup work?  A local dealer told me (AFTER I bought everything!)
that the A500 doesn't work well with DMA controllers.  Is this true?


Any help will be gratefully appreciated.
Thanks in advance
