Networkless because I only have wireless, and there's no driver for rt2x00 or rt2500/2570 on universal cd ... can a wireless USB dongle work in Gentoo PPC?

what's difference between saying ppc or saying G4 when identifying system?

I have a PowerPC 7450, any thing special I should do?

do I need to create filesystem for each partition, or only ext3 for hda4? is hda3 already swap, hda2 already bootstrap partition, of type HFS?

the installation guide is very good, but even as complete as it is it isn't comprehensive. lots of open questions.

Not at all sure what to put in USE, I want a desktop system with lots of options, gnome and kde and xfce, etc. seems that g4 desktop default set is really bare, no desktop environment (except X?) at all. is that right?

do I use genkernel all or genkernel --genzimage all, both are given in the instructions. I _think_ the latter is for Pegasos, but instructions in the handbook aren't clear...

many, many thanks...and doubtless more questions to follow...

Yes, with the appropriate drivers.

I think you're talking about the prebuilt binaries. In this case, ppc is the generic target. It'll run on most PowerPC devices. G4 indicates that it's built specifically for the G4 and includes support for things like Altivec.

Use the G4 profile or if you're compiling yourself, you can set your CFLAGS to -mcpu=7450, etc.

I don't understand what you're asking here, you might want to re-read the section in the handbook about disk layouts.

A default gentoo install doesn't even install X. If you need some guidance with use flags, I'd suggest two things. Emerge ufed, it's a utility for setting useflags and gives descriptions for each. Also, before you emerge a package, use the -av options to emerge to see what will be emerged along with the use flags available for each package.

"genkernel all" will work fine. You might want to configure the kernel yourself instead though as it's more reliable that way.

first of all, many thanks for your responses.

Yes, with the appropriate drivers.

but which drivers for my rt2500 device, when they do not appear in the universal CD? I can finish wirelessly, I hope, then add them once I can reboot from the hard drive not the CD, but can I just use the serialmonkey latest from their website, and recompile the kernel with them added?

clear enough.

ditto

I don't understand what you're asking here, you might want to re-read the section in the handbook about disk layouts.

at the end of doing mac-fdisk commands b and c, I see (with command p) that I've created hda 2, hda3 and hda4, as desired, and hda1 already is present. Then, with mke2fs -j /dev/hda4, I make that partition into ext3. But I never do anything comparable for hda2 or 3, or at least the handbook doesn't make explicit that I need to. Is that correct? Is it sufficient that I say, when I make /etc/fstab, that those two partitions play their particular roles? Or do I need some command, like mke2fs, to make swap and the hfs partitions (hda3 and hda2, respectively?)

I assume that's on the universal CD? sounds really helpful

I'll try it, I was rather in a rush when I chose to do genkernel.

many thanks

They're not available on the InstallCD, but you can certainly install them after you've completed the basic install.

There is a section for the swap called "Activating the Swap Partition", basically, you setup the partition by running mkswap /dev/hda3, then turning it on with swapon /dev/hda3. The bootstrap partition is setup later when you install the bootloader.

I'm not sure to be honest. If not, you can skip setting up the USE flags for now and get the system set up first. Later on you can rebuild all of the packages with changed USE flags when you do actually change the USE flags.
