SE/30, 7.5.3, and Mac Rom-inator

[unxmaal]

I'm working with a new (to me) Mac SE/30. I swapped in the board from my other SE/30, but didn't replace the HDD. This motherboard has been recapped, and has a Mac Rom-inator installed.

The new SE/30's HDD has Systems 6, 7.0.1, and 7.5.3. I had issues getting 7.5.3 to boot, so I assumed it was a faulty install, and installed a whole new 7.5.3 via "floppy disks" from my Floppy Emu. The new 7.5.3 didn't work either, because I'd totally forgotten about the required Rom-inator patches.

Woops.

Is there a reliable process to hack an existing 7.5.3 install into running properly, on a system with a Mac Rom-inator installed? I'd really rather not install off "floppies" again. 16 is Too Many.  :b&w:

Thanks!

You have to boot off of the rominator and modify the 7.5.3 files to work with the rominator:

This works now. All I had to do was, following the listed guide, and booting from the Rom-inator ROM disk, modify both the System file and the System 7.5.2 Update file with ResEdit, and restart.

Thanks!

Oh I’m just about to do a rominator install as well on my se/30, just awaiting new hhd with a fresh 7.5.5 on it plus 128mb of ram from owc (already got) as I don’t have any os install disks it’ll be tricky if it all goes wrong. Does the rom have res edit on it and did you find it easy to do the patch?

I don't believe the ROM has ResEdit on it. 

Patching is dumb-easy. Follow the instructions -- open each specified file (System and the update file, IIRC), click into gusd, find the 0018 offset (third from the top), click near the 03, change it to 05, save and done.

Before you get lost in a swamp, throw some more money at BMOW for a Floppy Emu. You can then easily download things you need from the Internet, and drop them into disk images that live on the SD card and that are seen by the SE/30 as floppy disks -- like ResEdit.

Just remember: hobbies are work that you pay for.
