Problem with Amiga 3000T , Please help !

[mdivancic]

So, again, here are the problems:
 
Amiga 3000T will not boot an 880k disk unless I first disable cpu cach.
 
Amiga 3000T will not recognize a hard drive after reboot.
 
Do any of you know what the default jumper settings are for an Amiga 3000T with onboard 68030, I need the default for all of the jumpers on the motherboard.
 
Thank you.
 
Oh, and as far as the battery is concerned, I know that Amiga computers work just fine without a battery, but, I do plan on installing a CR2032 battery holder and diode, because I plan to install Workbench 3.9 and I want the correct date and time displayed.  Do any of you know what diode I should use?  Will a 1N4001 diode work?

Spend some time on Google, there's a lot out there...

...another thought, check your SCSI termination. I believe there are, or should  term resistors on the motherboard (but I haven't seen a A3000 in years).

This information, as far as the jumpers, is basicly useless, because it does not tell you what the working default set by Commodore is.  What I really need is for someone that has an Amiga 3000T, that they have never messed with the jumpers, to pull the cover off and write down what the jumper settings are for all of the jumpers.  Or take a few pictures of the jumpers, showing how they were setup by Commodore.  This would help a lot.
 
Also, why would 880k disks refuse to boot unless you first hold down both mouse buttons and turn off cpu cashe?  I have never seen this problem on any Amiga computer.  It's got me scratching my head trying to figure it out.

I'm fairly sure the chart tells you, by revision what the jumper settings should be, but hey why bother helping?
