How do I get a 32bit clean ROM for my SE?
Posted by: mwigan on 2018-01-19 13:59:25
Ive got lots working on my se30, and am abut to install a pair of pds/interface ethernet cards(If anyone needs one I am using the A type in my machine, and I have the triple interface version pair-unsued- as well -which I can make available: yes i have the 1.2 driver floppy)

BUT I need to get up to the 128MB and 32 bit clean for au/x etc etc etc..so can anyone advise or help?

The software workaround is MODE32.  It's an extension that enables 32-bit memory addressing.  The best solution is to get one of these:

I bet if you ask BMOW, he might be able to load it with a 32-bit clean ROM before shipping it.

It ships with a Universal Mac II series ROM on board. Look at the specs on his page to check me on that.

My Rominator II sits in a drawer because I couldn’t get it to work with one of my machines. But that’s my fault, not its. So yes, I’d say this is a pretty good solution for you, as it is a 32-bit clean rom in its default configuration.

Confused. Do you mean SE? or SE/30?

Because, SE? You dont...

You don't need a 32 bit clean ROM for A/UX; A/UX itself doesn't make use of the built-in ROM after it gets past the bootloader, and for the Macintosh OS environment it uses its own modified software ROM that's already 32 bit clean.

A/UX allegedly has other issues with the SE/30. Long and short of it according to the FAQs is 3.0 mostly works but 3.1 breaks some things on older machines. And if you want to use something like a PDS Ethernet card your mileage will definitely vary.
