Hello all.

Does anybody else run Gentoo on an OldWorld beige G3 tower (266MHz)? If so, would you mind sharing your kernel .config? Right now I can get the 2005.0 CD to boot fine with BootX, but it doesn't seem to want to boot with any kernel I've compiled so far. As soon as I click the BootX "Linux" button, the MacOS logo changes color, but it never goes past that point, meaning I never see init's output. I suspected a problem with the frame buffer, but I've tried every PowerMac framebuffer device there is, and nothing has helped (I do have console framebuffer support enabled). I suspect I'm missing something stupid, but my brain has decided to stop cooperating.

Thanks for any help.

What options are you passing to the kernel on boot from BootX?

None, actually. Maybe I should experiment with that. I don't remember needing any on my 7300's Gentoo installation, but then I can't trust my memory.

You need to pass at least the options mentioned in the handbook to boot the LiveCD on an OW machine.

The LiveCD boots fine. Now I'm trying to get my installation to boot.

I tried passing a "root=" argument, using my root partition's device name, but that didn't help.

What's the error? I can't really help you without more information.

I wish I had more information to give, sorry. The only thing I see is, after clicking the "Linux" button in BootX, the MacOS logo changes color, and then the computer doesn't do anything more. I suspected there was an issue with the frame buffer driver, but I've tried every PowerMac-specific frame buffer driver, as well as the ATI Mach64 and Rage128 drivers since the G3 Tower has ATI hardware. That's why I was asking if I could see the kernel .config file of someone who had successfully installed Gentoo on a G3 tower.

If it helps, I'll post my .config.

Edit: My kernel .config can be seen here.

Beige G3 Tower should have a Mach64 card, but try passing console=/dev/tty0 to the kernel on boot.

Using the "console=" kernel argument didn't have an effect, however, I'm glad to say that I found the problem. As I suspected, it was something to do with the framebuffer, and as I expected, it was something stupid.

I finally looked where I probably should have looked in the first place, in the dmesg output after booting to the LiveCD. The ATI Mach64 frame buffer driver identified it as a 3D RAGE. Once I enabled support for "ATI Mach64 display" and for "Mach64 CT/VT/GT/LT (incl. 3D RAGE)," the frame buffer finally started working.

It baffles me how hard this type of information is to find on the Internet. That'll teach me not to look there first.

JoseJX, thanks again for your help.
