Booting Linux PPC on a 4400 Scsi

by Josef Gros » Wed, 08 Apr 1998 04:00:00

Hey,

this seems similiar to my problems on a 7300. Some guru told me to set
the output to /chaos/controll and the input to keybd, atutoboot to no.
OF might not react to your first try, so you will have to enter this
values a couple of times :-(

I haven't tried this yet, but I sure will

1. PPC 4400 and mol (long)

I'm trying to get mol to run on my PPC4400 and falling short of the
goal. I get as far as a producing a window filled with a gray (round
cornered) rectangle and the smilin' Mac in the center, but everything
stops there.

Here's what I'v done so far:
Compiled kernel 2.2.14 with the 603 patches in place;
Installed the kernel and System.map in /boot;
Put the stripped the ROM from my 8.5 CD in /usr/lib/mol/rom as rom.nw;
Put a version 8.6 System on an HFS partitionm and selected that
partition as the startup system with Conflect Catcher;
Put a bootable Zip cartridge in my Zip drive.

Here's what happens:
If I select the Zip as the first device, gray screen - no Smilin' Mac,
no drive activity;
If I select /dev/hda as the first device - gray screen - no smilin' Mac
and sounds of brief activity on the disk drive (no activity LED);
If I select /dev/hda14 ( the HFS bootable partition) as the first device
- gray screen - smilin' Mac and sounds of brief activity on the disk.

In all cases the launching window displays:

Can anyone suggest a next step?
