I had a couple hours to play with it today and it is mostly working. I think my IIfx ROM SIMM may not be any good - just does weird stuff when it's installed. Bummer. Sometimes it will not complete a boot, sometimes it will just hang on the simasimac screen, and it definitely does not like either my 2GB hard drive or the Radius Full Page Display card. I was really hoping to use it and run 7.6.1 since I have been saving the stupid IIfx ROM for this specific purpose for like 10 years.
So the configuration I finally got working was booting from a 7.5.3 retail CD, and using the patched HD SC setup to format the drive into the 1.5GB and 500MB partitions, and then install the operating system in the larger one. Previously, I had tried the opposite of that because I wanted a large partition for applications, but I guess it's whatever. I am also using the SE/30 ROM, and 32MB RAM. Mode32 works great now too.
I guess I was wrong earlier when I said I had 24MB also... as it turns out, what I thought were 2MB modules were really only 1MB. I still have no idea why I was only seeing 8MB when there was really 20MB installed but I guess it doesn't matter now.
