Need SCSI configuration help :(

what's supplying power to the external active terminator?
is it bus powered, or the cd drive providing the power?

its possible the old HDD was supplying power to the bus, and now without it, there is no power for the active terminator...

as for why you can copy to the ram disc... no idea! lol

[AmmoJammo]

I'm not sure that really answered the bus powered/device powered question...

The scsi hdd I have, has jumpers to power its own terminator, supply power to the bus (for active terminators on another device), or use the bus for power for its own terminator.

I dont think the cdroms terminator is active anyway

on another note!

my cdrom drive, connected externally to the A590 scsi controller, doesn't work properly when I have the tomthul 8meg enabled in my A500...

[AmmoJammo]

ram disabled in the A590.

I thought your 4meg might have been under the 68k, but if its in the GVP, it shouldn't be an issue.

I dont suppose you have a cable to connect both devices to the internal scsi header?

[AmmoJammo]

tomthul's 8MB expansion that I had as it states uses the entire 8MB RAM space so no room for the A590's 2MB. :-/

2MB needs to be disabled on the A590 or you get memory address clashing ;-)

please read the first line you quoted... :p lol
