Hi all,
I managed to install R5 on a PowerBook G3/300, but I could not get accelerated
video running. I used "video=atyfb:vmode:14,cmode:32,mclk:xx" with xx from 63 to
73, but got always the "garbage screen". Has anyone had better results?
Thanks for your help, Albrecht.

Which kernel version is shipped with R5? Does the kernel tell you the estimated
clock crystal frequency (XTAL) during the initialization of the ATI frame
buffer device (atyfb)? If not, they're using a kernel without the clock crystal
frequency estimation patch (present in 2.3.6).
Greetings,
Geert

The kernel version is 2.2.6. If I start with the "No video driver" option
checked (from BootX), the startup messages siplly tell me that
MacOS display is /pci/ATY,RageLTPro
Using unsupported 1024x768 ATY,RageLTPro at 82801000, depth=32, pitch=4096
Console: switching to colour frame buffer device 128x48
fb0: Open Firmware frame buffer device on /pci/ATY,RageLTPro
Unfortunately, I can not telnet yet to the PB, so I can't see the startup
messages when I use the atyfb option...
Thanks, Albrecht.

Hence you need the clock crystal frequency estimation patch to be able to use
atyfb and acceleration.
Copying drivers/video/atyfb.c from 2.3.6 should do the trick.

In the meantime, I got telnet running (was missing in inetd.conf), and booted
with the atyfb option, mclk set to 63. Now dmesg tells me upon boot:
MacOS display is /pci/ATY,RageLTPro
atyfb: 3D RAGE LT PRO [0x4c50 rev 0xdc] 4M SGRAM, 230 MHz PLL, 63 Mhz MCLK
Console: switching to colour frame buffer device 128x48
fb0: ATY Mach64 frame buffer device on /pci/ATY,RageLTPro
Copying drivers/video/atyfb.c from 2.3.6 should do the trick.
I will try it...
Thanks, Albrecht.

Installed it, and now...
MacOS display is /pci/ATY,RageLTPro
atyfb: 3D RAGE LT PRO [0x4c50 rev 0xdc] 4M SGRAM, 29.498928 MHz XTAL, 230 MHz
PLL, 100 Mhz MCLK
I could not (yet) get X configured, but the system console comes up with the
atyfb video driver. (BTW, should I add "mclk:100" to its arguments?).
THANKS A LOT, Albrecht.

That's not needed: atyfb uses a 100 MHz memory clock by default for the 3D RAGE
LT PRO, as it reports.
