Problem with Amiga 3000T , Please help !

[don27dog]

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?

Here are the 3000T jumper settings
