I have a working tri-boot setup with MacOS 9.0.4, Mac OS X DP4, and Yellow Dog Linux > Champion Server 1.2. I'm using yaBoot to boot the machine (BootX causes it to lockup instantly, and often it simply turns off when I try to use BootX) and as on now, Kernel > is 2.2.17pre10-ben1 I'm using a 64MB iBook (192MB RAM, 6GB HD) without an AirPort card. And I'm facing different troubles: > First, the video trouble. Using the version of XFree that came with YellowDog, X runs in 800x600x8, which is very ugly. After about 15-30minutes of using X, the screen > would polarize and the computer would lock up hard (dead to pings etc). So, I decided to upgrade to XFree 4, because that was listed as a solution for iMac trouble on > Yellow Dog's page. I installed XFree 4, and although the lockups are now gone, I have a new (odd) problem. The left 1/4inch of the image is displayed on the right > 1/4inch of the screen =) (Slightly raised up too) There's no overlap, the entire screen is shifted to the left like this, and I'm still not able to get anything better than 8bit color. > In XFree's messages, I can see a message indicating that it thinks the video card has 468K of RAM. This sounds like it is still using offb (atyfb reports 4MB for me, offb 800x600 bytes ;-). The screen move is due to a wrong base address calculation in XFree, I heard some rumors it was fixed in more recent XFree drivers (maybe even in 4.0.1). Looks strange. What about video=ofonly? Does this work for you. IMHO a stable video system is better than a fast video system. You might even give SuSE's beta XFree: ----- XFree86 Version 3.3.5 / X Window System (protocol Version 11, revision 0, vendor release 6300) Release Date: August 23 1999 If the server is older than 6-12 months, or if your card is newer than the above date, look for a newer version before reporting problems. (see http://www.XFree86.Org/FAQ) Operating System: Linux 2.2.14pre9SuSE ppc [ELF] SuSE Configured drivers: FBDev: Server for frame buffer device (Patchlevel 10): mfb, afb, cfb8, cfb16, cfb32, NCR 77C32BLT (accel), ATI Mach (using VT number 7) --- a try. It does it's work here for three months and has never crashed my machine (8h/day use). Though with 16/32bpp the server restarts once the screensaver activates. > There's a few other minor troubles (mainly with making MacOS not unbless my yaboot partition...) but these two ar e the big ones =) Any help is appreciated. Try changing the type (delete, recreate via 'C', worked for me) to Apple_Bootstrap. After this it booted well (for me), before this I saw the MacOS logo again. What about Open Firmware (see my recent communication with Ben H., he has good points on this) Christof PS: You may not be able to reach me within the next three weeks, I'm leaving for holiday 18:00 CEST. ** Sent via the linuxppc-dev mail list.
