Page fault in FreeBSD-7.0: How to set dumpdev when installing from bootonly cdrom

[Juergen Leising]

Hello,

I fail in installing FreeBSD-7.0-RELEASE from the bootonly cdrom
at an AMD 3000 Sempron (not a 64-bit processor):
Page fault (trap 12).  So I would like to produce a proper crashdump.
How do I do this?

On an already installed system I would set into /etc/rc.conf,
whith ad0s4b being a swap partition:

	boot_verbose="YES"
	verbose_loading="YES"
	dumpdev="/dev/ad0s4b"
	dumpdir="/var/crash"

But what if I install a fresh distribution from CD?

I could remaster the bootonly cdrom. But which files do 
I have to change, then, to get a crashdump?

Or would some kernel parameters be sufficient?

BTW: The snapshot 200806-bootonly-cdrom also caused a page
fault to me.

Bye, bye

Juergen
