Question about A3000 Roms

[AmiDude]

OK, this is the question:
I picked up an A3000 with a rev. 6.1 MoBo.
It's fitted with the standard 37.175 ROMs
on U182 & U183. See link:

Linky Link

The ROMs automaticly put the ROM into FastRom on boot,
taking 0,5MB FastRam from the system.
(I've got 2 other A3000's (rev9), and they don't take
automaticly 0,5MB FastRam from the system).

Now I want to put other(newer) 2.04(37.175) ROMs on the MoBo.
Where do I put Them? On the empty U180 & U181 sockets,
or do I switch them with the older ROMs on U182&U183? Because I don't want the system boot into FastRom.
Any help please.

The loading of the ROMs into fastram isn't part
of my startup-sequence, so I guess I have the
KS1.4 Boot-Roms then? They are the same as the
ones pictured on the link.
I want to put in this other ROMs:

"V2.04(37.175) ROM0"
"390629-03 9204 D"

and

"V2.04(37.175) ROM1"
"390630-03 9204 D"

Is it OK to do so, and if yes, do I put
them on U180&U181 or U182&U183?
(Don't wanna make any mistake... My other A3000's
 have rev.9 and 3.1ROMs and I'm not familiar with this
 rev.6.1 MoBo and KS1.4 Boot-Roms or ROM Tower.)

[AmiDude]

There's no MapRom command in C: or in the startup-sequence,
but a grey screen does appear upon boot with
"Loading Kickstart 2.x" printed and then rebooting.

OK, thanks! I think I'm gonna change the ROMs
with the other 2.04 ROMs (don't have 3.1),
and see what happens.

The 2.04 ROMs won't work. Tried them on U182&U183
and U180&U181. I replaced them with the original
1.4 Boot ROMs.

I've seen all the pics on BBoAHW but that's no help.
Now I've got another question about the J180&J181
A2000 Compatibility jumpers. I've started another
thread about that...
