A2000 & SCSI acting very strangely!

[shayes1981]

Hello all!

Well, I posted a few months back when my A2000 all of a sudden quit booting and working as it had.  I never quite figured it all out - I could get it to boot regularly, provided that I had something else plugged into the internal ribbon cable.  If I had something external, it wouldn't boot from cold (I usually had to leave it on for 5 minutes or so, then shut the computer off, turn it back on, and it would boot.).  However, at this point, my external scsi stuff wouldn't necessarily work, and I never got my previously working scanner to work.  It did this both with my accelerator (GVP 030 Combo), and my A2091.

So, I decided to buy another A2000.  It's here, and doing the same thing.  Very strange . . .

Got any ideas?

@shayes1981:

It might not be because the GVP card has onboard termination giving you a termination in the middle of the SCSI-chain when you have both internal and external units?

Check the section "Termination" on this page for more information.

I found I had to have the units plugged into the SCSI connectors closest to the SCSI card - if I put them further down the cable (for convenience) it wouldn't register them at all.
Also set the terminator on the last device connected, and made sure each device had an individual unit number selected (between #0 - #6, leaving #7 free, as this in the unit of the scsi bus).

Hope this helps.

Was just about to link to the same page as patrik before noticing the URL :-D
