About USB IRQ sharing fix:
Fix for IRQ sharing problems of USB controller and graphics card.

If the USB controller (mainly OHCI) and the graphics card share an IRQ, some system crash during boot. This fix modifies the boot script to make sure that the USB driver is loaded first which seems to solve the problem. I used the Zeta bootscript as a base though it should work on all BeOS versions.

It's tested with an ATI Radeon graphics card but should be applicable to nVidia graphics cards as well.

Make sure you have a boot CD at hand to be able to restore the bootscript if this patch goes wrong!

Latest Version
   
Details about this version:
Dirty hack that simply replaces the boot script. Unfortunately, the boot script is BeOS version specific, so it may not work for you.

Thanks go to Ithamar for tweaking the USB driver so we could locate the problem!
