I have a powermac g4. It's blue. I guess that means it's a Digital Audio or Gigabit but I'm not sure which one. I've ran OS X on it for several years now but want to switch it to a gentoo only box. The internal cdrom drive is not working right now. I'm not sure if it's broken or configured wrong as I had to get a new PCI card to support a 300 gig hard drive and afterwards the cdrom drive seemed to mess up (it makes a strange noise and often spits the disk back out). I have an external LaCie Firewire cdrom available. Is it possible to boot the installation CD from this drive? If not, is it possible to boot the CD from another computer for installation on the g4 just mentioned?

*EDIT* I'm using a Sonnet Tempo ATA-133 PCI card to support my large capacity drive

I replaced the cdrom drive (actually a DVR, a shame it's broken) and the installation cd boots. Something strange happens when the prompt is reached. Text follows:
Code:
livecd root # hdg: dma_timer_expiry: dma status == 0x21
hdg: DMA timeout error
hdg: dma timeout error: status=0x51 { DriveReady SeekComplete Error }
hdg: dma timeout error: error=0x84 { DriveStatusError BadCRC }
ide: failed opcode was: unknown
hdg: dma_timer_expiry: dma status == 0x21
hdg: DMA timeout error
hdg: dma timeout error: status=0x51 { DriveReady SeekComplete Error }
hdg: dma timeout error: error=0x84 { DriveStatusError BadCRC }
ide: failed opcode was: unknown


I hit Ctl-C to return to the prompt, continue on to Preparing the Disks and /dev/hda does not exist. It looks like I should use /dev/hdg, but I'm worried about the previous error(s)?

A couple other things: there is no mark for my cursor and when Tux appears at the top of the screen on boot, he is very blurry / pink like 8 bit colors or something.

*EDIT* More to add: Tab completion occasionally causes the machine to entirely freeze up. I can't access any other virtual terminals or Ctl-Alt-Del when this happens.

hda wouldn't be the correct device since you're using a different IDE controller. Usually, the IDE controller that's built into the mainboard is hda-hdd. Additional devices are named depending on the order that they're found. Check your dmesg to know for sure which device is which. Depending on what device hdg is, that could be a bunch of different things. If it's a hard disk, errors like that are usually indicitive of a dying hard disk. It could also be a kernel issue, you might want to try a different version of the InstallCD and see if that makes a difference.

The other issues sound like framebuffer issues, try passing video=ofonly to the kernel on boot and see if that helps. What kind of video card is in that machine?

The lockup on tab complete could also be a kernel issue. On some machines, the "beep" locks up the machine. You could try removing the sound drivers and see if that helps.

ppc32 video=ofonly did not fix the penguin problem
Using a 2005.1 cd did fix the error message. Tab completion and a successful install remain to be seen.
My video card is an nVidia Corporation GeForce2 MX/MX 400. Is this going to be difficult to configure (e.g. the kernel)?

I just reached the section where I chroot. When I chrooted I got the same error messages concerning the hard drive as before only this time with hde instead of hdg.

It sounds like a hardware issue, are you sure the disk is okay? How about the filesystem on the disk?

nVidia cards are annoying on PowerPC, there are no open source drivers for 3D acceleration, and only a very poorly written 2D driver. It will work, but there are always issues. :( With the 2006.0 livecd, try video=nvidiafb and see if the penguin works better.

The disk should be fine. I was using it on another machine not to long ago. I certainly don't want it to crash when I start putting personal data on it. Is there any way to be certain it's OK?

I finished the install and rebooted. Yaboot came up and then went to "Loading second stage bootstrap..." A mac icon / finder guy started blinking in the center of the screen and then the screen went black.
