PowerMac 9600 video questions
Eric Deveaud
Hi,
I'm setting up a powerMac 9600/350 (currently 128Mb ram but should jump
to 512 soon) with 2 HD (2Gb MacOS / 9Go Debian woody)
install method was:
get Ramdisk.image.tgz vmlinux from potato
boot with BootX
minimal NFS potato install
edited /etc/apt/sources.list to point to woody
apt-get dist-upgrade.
I was unable to install woody directly, it always fail when looking at
Release or basedebs.tgz
runs 2.4.18-pre7-ben0 from this morning rsync.
currently everything runs fine, except X
dmesg gives me the following (selected parts)
MacOS display is /bandit/IMS,tt128mb8A
Using unsupported 1024x768 IMS,tt128mb8A at 92000020, depth=32,
pitch=4096
Console: switching to colour frame buffer device 128x48
fb0: Open Firmware frame buffer device on /bandit/IMS,tt128mb8A
lspci shows me the following
zig:~ > lspci -v

03)

Memory at 92000000 (32-bit, prefetchable) [size=16M]
Expansion ROM at 90000000 [disabled] [size=64K]
I have configured /etc/X/XF86Config-4 this way
Section "Device"
Identifier "hummm"
Driver "ati"
BusID "PCI:1:15:0"
Option "UseFBDev"
EndSection
BUT cause ther's always a but. ;-))
startx faill and complains this way (taken from /var/log/XFree86.0.log)
(EE) No devices detected.
Fatal server error:
no screens found
on other hand /var/log/XFree86.0.log shows me the following
(--) PCI: (1:15:0) IMS TwinTurbo 128 rev 1, Mem @ 0x92000000/24, BIOS @
0x90000000/16
the card was probed on the expected BusID.
I must tell , that I'm going crazy, and have a big headache trying
to figure out where's the problem
Thank's in advance for any help/input/tip ;-))
Eric
PS I can put on a web page the full XFree86.0.log, XFXF86Config-4 and
output that could help.

The ati driver only works with ATI chips. ;) Try imstt or fbdev.

OK the story is continuing....
the context
PowerMac 9600
video card IMS Twin Turbo (IMS,tt128mb8A)
booted with BootX
kernel 2.4.18-pre7-ben0 with CONFIG_FB_IMSTT=y
booted with BootX
1) when giving extra kernel argument video=imsttfb
with or without "force video setting"
the machine boots fine, but after the few first kernels messages
the screen goes black.... I don't see any kernel boot messages, I have
to type blinkly.. or ssh the machine in order to reboot
I have to boot with video=ofonly in order to get the console screen.
2) setting XF86Config-4 to use
Driver "imstt"
VideoRam 8192 # the 9600/350 comes with 8Mb on card
and startx gives me something like uper half screen with a kind of
display the other (lower half) black.
furthermore, the upper half part is cutted in 2 parts (left rigth)
something like that
+---------+---------+
| | |
useable quarter | | | like mirrored of the "useable
| | | quarter"
+---------+---------+
| |
| Black |
| |
+---------+---------+
furthermore /var/log/XFree86.log tells me the following
(--) imstt(0): probed videoram = 3072k
Thank' for any advice.

Anything from imsttfb in the kernel output? Maybe you have to tell it the
mode to use?

Is this the same for all depths?

It would be interesting to know what imsttfb thinks about this. :)
I don't know the status of the imstt driver on powerpc; it could be
plain broken. You could also try the fbdev driver.
