I just installed gentoo on a G4 Mac. yabootconfig ran successfully but when attempting to reboot nothing happens except a folder with a Mac icon and a flashing question mark appears.

The Apple_Bootstrap partition is sda2. sda3 is swap and gentoo is installed on sda4.

Any help is appreciated.

Well, most G4 macs don't have a scsi controller. Is this your primary disk? Or maybe a firewire disk? What kind of G4 mac exactly?

It is the primary drive. It definately has a SCSI controller. The output from lspci listed a SCSI controller:

00:0b.0 Host bridge: Apple Computer Incorporated UniNorth AGP
00:10.0 VGA compatible controller ATI Technologies Incorporated Radeon R100 QD 7200
10:0b.0 Host bridge: Apple Computer Incorporated UniNorth PCI
10:0d.0 PCI bridge: Digital Equipment Corporation DEC chip 21154 (rev 05)
11:04.0 SCSI storage controller: LSI Logic/Symbios Logic 53c1010 Ultra3 SCSI Adapter (rev 01)
11:04.1 SCSI storage controller: LSI Logic/Symbios Logic 53c1010 Ultra3 SCSI Adapter (rev 01)
11:07.0 Class ff00: Apple Computer Incorporated KeyLargo Mac I/O (rev 03)
11:08.0 USB Controller: Apple Computer Incorporated KeyLargo USB
11:09.0 USB Controller: Apple Computer Incorporated KeyLargo USB
10:0a.0 Firewire (IEEE 1394) Texas Instruments TSB12LV26 IEEE-1394 Controller (link)
21:0b.0 Host bridge: Apple Computer Incorporated UniNorth Interval PCI
21:0f.0 Ethernet controller: Apple Computer Incorporated UniNorth GMAC (SunGEM)(rev 01)

Will that cause a problem with the installation?

No, it's just different than usual. When you ran yabootconfig, did it successfully bless the disk? What does your yaboot.conf look like?

here is the output from yabootconfig:
Code:
yaboot is the Linux Loader for PowerPC.  yabootconfig sets up your system to boot directly
from your hard disk, without the need for a boot CD, floppy or a network boot.
Install yaboot bootstrap on /dev/sda2 to boot Linux from /dev/sda4? [Yes] Creating a simple /etc/yaboot.conf...
Running mkofboot to make the disk bootable...
Done


and here is /etc/yaboot.conf:

Code:
boot=/dev/sda2
device=/pci@f2000000/pci-bridge@d/ATTO,ExpressPCIProUL3D@4,1/@1:
partition=4
root=/dev/sda4
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/vmlinux

I'd be guessing that SCSI controller doesn't have OpenFirmware?

It may not be recognized properly. Can you type:

ofpath /dev/sda2

What does that return?

Well, that seems right. Can you run ybin with the -v switch so we can make sure that it's writing the nvram and blessing the partition properly?

Well, that looks okay too. If you hold down option when you power on, what disks show up as bootable?

The Gentoo Install CD is the only disk that shows up.
