Kernel: Version 2.2.14
Known problems with the kernel
- you can not use more than 768MB on an IM RS/6000 machine, the rest will stay unused.
- on PowerMacs with more than 700MB you have to specify the kernel argument "
mem=700M
", otherwise the machine will not boot.
- the graphics chip of the iBook is not supported right now, specify the kernel argument "
video=ofonly
"
- the platinumfb driver used in PowerMac 7200 display garbage if you boot with a resoltuion of 832x624 and a color depth creater than 8 bit. Solution: setup another resoltion or color depth
- older Wallstreet PowerBooks, mostly the 233 Mhz models, display garbage while booting. Pass the following kernel bootargument in the BootX kernel args line:
video=atyfb:vmode:14
The vmode:14 seems to be the only requirement
If your PowerBook supports only 800x600 specify vmode:10
- on PowerMac 9500/9600 only one PCI bus can be used, the second bus can not be used right now.
- some internal modems are unsupported, we have reports about the Performa 6400. Other Performa models maybe also affected. The modems in iBook, iMac, PowerBook are supported. Externel serial modems should work. Use wvdial as dialer software.
- SMP was broken in recent Linux kernels. It seems to work again with 2.2.17pre3. To use the SMP feature of the kernel download the current Linux kernel sources from a mirror of http://www.kernel.org/, get the pre patches from the
people/alan/2.2.17pre/
folder, choose CHRP as architecture and the SMP feature.
- SMP seems to work also on PowerMac 9500/9600 SMP machines, instructions can be found here:
