Written by Matt Porter from Motorola. http://members.home.net/mmporter/linux/ Could I do the same thing with your bootloader?

I'll give your 2.4 a try. I need to get atleast one more PMC disk so I can have one stable and one unstable evironment. On an unrelated subject. I would like to have a Linux-board as SYSCON on the VME bus that is able to generate a reset on the bus but doesn't listen to it. Have you got any idea if it would be possible to modify a MVME-card that way? To me it looks like it would be possible to disconnect the signal from the Universe-bridge. /Micke ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
