Dear fellow MOS / MacPPC users,

I have been thinking how to improve my iMac G5 experience

PROBLEMS
Apple BIOS is in tiny fonts and my eyesight is operated and bad (ablatio retinae)
and its hard to find some special characters. Any help here is greatly appriciated.
Entering BIOS and booting from CD requires strange key combo at least for PC Amiga users :D

My G5 is second hand, has a bit bad speaker sound and not so clear screen and just 1GB RAM and mechanical drive, and has installed Leopard on drive and I boot MOS from CD.

I have managed to install MOS only by formating whole hard drive.

Even I have extensive experience with CFE, some with Uboot and have tried all PPC Linuxes on x-1000
I did not manage to start Linux PPC install.

I understand there is no GUI Boot menu a la GRUB possible. Is there a simple way to enter BIOS and boot from some parition, like UBoot had boota, bootb or similar command or CFE had path line from where to start?

WISHES

- Hardware upgrade RAM to 2-4GB if possible for MacOS and Linux
- HW upgrade: Installing clean larger SSD that can work with old SATA? Which models?

Pointing 101% working parts on ebay, offering them for late 2024 or early 2025 would be grately appriciated

- SW upgrade: installing to hard drive, Registering MorphOS at end of 2024 (is it 100e for G5 via PayPal?)
- SW upgrade: IF possible, installing that "unofficial Snow Leopard PPC" crossmix with latest updates that I find on Mac forums and Mac Garden

- SW upgrade: IF possible, installing Linux PPC (prefered LinuxMINT or Debian based distro with LXDE and MATE, plus some browser and some version of Libre)

- SW upgrade: Out of those 3 OSs which can easily emulate Classic MacOS 8.1 m68k or MacOS 9 PPC?
This is a bit trivial, but I prefer MacOS Classic look to OS X. Or can OS X look more like

- SW upgrade: Linux Can read FAT32, can MacOS and MOS do it too, so I make 4th data exchange partition?

Would pay small fees via Pay pal for assistance at end of year, this is just planning phase.

And will encourage DJ Nick to register MorphOS on his SAM460, deleting OS 4.1 :D

> I understand there is no GUI Boot menu a la GRUB possible.

GRUB is possible on G5 Macs. The inofficial Debian PPC64 builds depend on it.

> Hardware upgrade RAM to 2-4GB if possible for MacOS and Linux

2.5 GiB is the maximum for the hardware.

> SSD that can work with old SATA? Which models?

You may start from that thread:

> is it 100e for G5 via PayPal?

"The price is 79 EUR for one laptop or desktop computer. Special pricing of 49 EUR per device is offered for EfikaPPC and Sam460 systems."

Yes, they can of course. For file size over 4 GiB and/or partition size over 2 TiB, I'd recommed ExFAT or NTFS-3G, though. I'm not sure about ExFAT for PPC Mac OS, but NTFS-3G exists for it.

> will encourage DJ Nick to register MorphOS on his SAM460, deleting OS 4.1 :D

There's no need to delete OS4 in order to use MorphOS on the Sam460 :-)

Thank you wise man!
So 1 x 2GB RAM, which specs?
Recommended SSD that can work on G5 old SATA quite well?
GRUB - can it pick MOS and MacOS X choices?

I wonder could MacOS X see NTFS partition, that is why I opted FAT32 for data exchange partition.

Deleting OS4 is personal vengeance :D

DDR2 SDRAM, DDR2-533 PC2-4200 or faster.
The 2.5 GiB maximum is outdated Wikipedia info, sorry. People have managed to get up to 4.5 GiB to work:

See the linked thread, and threads linked from there.

> GRUB - can it pick MOS and MacOS X choices?

Good question. I don't know, sorry.

>> I'm not sure about ExFAT for PPC Mac OS, but NTFS-3G exists for it.

Yes, at least with NTFS-3G installed.

Thanks for answers.
Would DDR2 666 4GB work?

Will come back soon with some PPC Mac users hints too!

I guess so.
