G4 Dual Processor and LinuxPPC: SCSI issues

Post by Bret Van Hor » Tue, 12 Sep 2000 10:36:29

Okay, first off, I'm a newbie with linuxPPC, so be forewarned that I am
probably making some horribly obvious mistake.

That being said, here's what I have done:

I got the vmlinux_ibook kernel (which I saw a post about working with the
new G4s) and tried to boot off of it on an HFS+ partition.

So I see the penguin, and it starts to go through the whole routine of
booting up and detecting all of the devices on the machine.

It seems to do okay until it gets to the Adaptec 2930 SCSI card Apple
installed at the factory. It queries the card, downloads the info from the
card's firmware, then it hangs on the following line (sorry I wasn't in a
situation where I could copy the whole boot sequence):

SCSI: Aborting command due to time out: pid 0, SCSI0, channel 0, id 0, lun
0, test unit ready 00 00 00 00 00

Does anyone have any idea as to what I might be missing/doing
wrong/forgetting to pray for? I've tried it with and without any SCSI
devices hooked up to the chain, and the card is supposed to be

Thanks in advance,



1. YDL on G4 dual processor

I tried to boot G4 dual processor Apple machine with a YDL 1.2 CD.

To boot it I had to remove the hard disk connector as It was always
booting MAC from the hard disk. I dont know how to change the boot

While booting it gave messages like loading usb driver for Keyboard
But finally it gave usbcore : device not responding error (-101).
Is this a known problem. I do not have any port other then USB for

How do I make it detect keyboard. Is the problem with the driver ?
Tell me any other way to boot it ..
