A3000 030/25 and MMU

[wlemonds]

Hi,

I have the revision 9/03 motherboard, 2 meg CHIP, 4 meg FAST onboard 80ns ZIPS. 030/25 Mhz/882 FPU.

EDIT: Has KickStart and WB 3.1

When I run Sysinfo it says that the MMU is disabled and when I try to run CPU MMU or SETCPU MMU the computer locks up.

I added a Rapidfire ZII board with 8 megs and still can't get the MMU to work.

Does this model in fact NOT have an MMU?  :-?

CPU : MC68030FE25B

According to that, 68030s have an integrated MMU, 68EC030 does not. Since you have a 68030 (according to that chip ID), perhaps SysInfo is looking for an MMU which is not integrated in the CPU but in another chip? I've got no idea if thats true, but Sysinfo on my 68030/40 says the same thing.

By the code you have a fully working '030. Did you edit the s-s with "CPU Fastrom" in the very first line?

Thats normal, use showconfig in Workbench/tools. That will verify your setup.

BTW: sysinfo (and other alike programs) only report a working MMU if you use it!

 Put the line CPU FastROM in the very first line of your startup-sequence.

 IF the 3k hangs, you only have to boot with no startup-sequence, mount the ENV: and edit the line again.

Thanks guys!

It's been along time since I last ran this machine and had to format the drive and I forgot about the CPU FASTROM on the first line of S.S.
