System: NetBSD eros.endersgame.net 1.5X NetBSD 1.5X (EROS) #0: Tue Sep 4 21:23:43 EDT 2001 dive@eros.endersgame.net:/current/src/sys/arch/i386/compile/EROS i386
Architecture: i386
Machine: i386
>Description:
the random number generator on the 82443BX host bridge is not supported in
pchb_rnd.c, but once a hook is added, it is enabled and initialized on
bootup, and works perfectly as a source of entropy.
>How-To-Repeat:
boot a box with that chipset and notice that you dont see it enable the
random number generator? I dunno
>Fix:
cd to /sys/arch/i386/pci, and apply the following patch:
