I haven’t tried it myself but there is this post on apple.stackexchange that might offer some insights.

Thanks for the recap, James. Out of curiosity I pulled a photo of my SE logic board to see what I have. I have the new FDHD logic board with the old ROMs and IWM. It’s my lone Mac with an 800k floppy drive. Thanks again!

Yes, OCLP updates remove the OC directory from the EFI and install a new one, meaning we have to reapply the mods to the config.plist file after every update, as you discovered. Thanks for the script!

You’re welcome, glad the solutions are working for you. After a few months of testing with my 2015 MBP, I found Method A would lead to occasional boot problems that I think are associated with the drivers loaded with the boot picker. Method B just works, and it is what I’m currently using on...

Addendum. While I was testing the Quadra 630, I used the Apple Multiple Scan 15 Display that came with it, and for which @eric very kindly donated a swivel stand for it a while back. Unfortunately, during the testing with the Quadra 630 the CRT exhibited a flickering screen and a hissing and...

Two years ago I received for free a Quadra 630 from a family friend. Back in the day, I had a Centris 650 bought new in 1992 which I replaced with a PowerBook 5300cs purchased later in 1996. Hence, I completely missed this model and its cousins, and was completely unfamiliar with it. The...

For my final project for #MARCHintosh 2024 I installed A/UX 3.0.1 on my overclocked Centris 650. I primarily followed Eric Edge’s guide with a modification. Rather than using a burned CD and CD drive, I was successful in using a BlueSCSI version 1.1 with the CD features implemented in firmware...

For Marchintosh 2024 I’m tackling a project that has been on my list for a while: overclocking a Centris 650. The Centris 650 was the first Macintosh I purchased for home use back in the day, and at the time I was blown away by its performance relative to the Macintosh SE/30s I was using at the...

Addendum for iBook G3.... The livecd disk presented a black screen near the end of the boot sequence. This is fixed by entering a kernel parameter in the grub menu, "nomodeset" with no quotes. For the record, here are the /proc/cpuinfo and lspci details: livecd /mnt/gentoo # cat...

I’ve been tinkering off and on for nearly a year with Gentoo Linux on a 800 MHz iBook G4 from 2003. As you may be aware, pickings are slim for active Linux distros that support PPC. Besides the excellent Lubuntu 16.04 Remix by @wicknix, and Adelie Linux, the only other option that I found is...

My first guess is along the lines of what @phunguss said, from my experience of restoring a Classic II. It will need a recap of the surface mount electrolytic caps if it hasn’t already been recapped. The Classic II also comes with RAM soldered to the logic board that also serves as video RAM...

Following. My Pismo’s original battery is still functional but doesn’t hold much of a charge anymore.

My latest escapade in PPC Linux for the PowerPC Challenge was attempting to get Gentoo Linux running on another iBook G4, which has been a big fat fail so far and of course the month of January is now behind us. I haven’t given up yet and have been slowly chipping away at an installation where...

I wrote about my experience installing Lubuntu 16.04 Remix on a white iBook G4, which went quite well. https://tinkerdifferent.com/threads/dual-boot-lubuntu-16-04-ppc-remix-with-mac-os-x-on-white-ibook-g4-800-mhz.2778/

In my case, my IIci shows a black screen and no boot chime at startup with a bad cache card installed. Without the card, the IIci chimes and boots normally. From there, running a tool such as what @Garrett used or a benchmark tool to verify performance.
