Good Morning All, I have completed the upgrades to my SE/30 and I thought I'd share my experience. I replaced the system HD with a 16 GB SCSI2SD divided into 5 partitions. The first one I kept down to 2 GBs for compatibility, three more sized at 4 GBs, and the final leftover is 718 MBs. The ROM-inator II has a compressed ROM disk using OS 7.1 but I ran into problems using the Apple HD SC Setup program 7.5.3 as it wouldn't run under 7.1. Also the OS 7.5.3 install disks wouldn't boot with the clean ROM installed; it would freeze at the welcome screen (but it booted fine with the original ROM). Since I have a SCSI2SD in my LC475 and it can boot it into 7.5.5 from an external drive, I used it to partition the 16 GB SD card. It worked fine which then allowed me to start on the OS install in the SE/30.
The OS install/patch procedure for the SE/30 is required as it looks at the gestalt ID and the OS 7.5.3/7.5.5 installations will fail if it doesn't get the expected results. The clean ROM usually comes from the ROM-inator II SIMM or a borrowed IIsi or IIfx SIMMs. This allows the SE/30 to run in true 32-bit mode instead of 24-bit mode and access more RAM. In my case this SE/30 has 128 MBs. The procedure refers to first installing OS 7.0.1 and 7.1 as they don't conflict with a clean ROM. As it turned out that was unnecessary. I could boot from the ROM-inator II's ROM disk and run the 7.5.3 installation from disk (or EMU Floppy) which did work and I performed an Easy and Clean install. Then reboot into the ROM disk and run ResEdit 2.1.3 to edit the System 7.5 Update and System file in the System Folder. I found System Picker 1.1a3 and Mode 32 v7.5 to not be required.
Afterwards, I installed the OS 7.5.5 update and patched it successfully. Finally, I added the updates for building a modern System 7.5.5. So the SE/30 works great and working the way I want it. If any further details are needed please let me know.
I do have a question but I'l post that separately as it's on an unrelated subject.
Thank you,
Gerry
