7043-140 and NetBSD 7.0.2 problems

[Simon Vannarath <simonvannarath%gmail.com@localhost>]

Hi mailing list,

I dusted off my old IBM 7043-140 PReP machine which had an old 
installation of NetBSD 5.2.3and tried installing the latest version 
(7.0.2) and found that booting the serial console sysinst imageseither 
by CD or netbootwasn't successful.I tried 6.1.5 and while the sysinst 
image went through the whole install process without problems, booting 
the kernel on the disk fails with a blinking cursorwith the LED code FDD 
(Early processor exception).

Anyone with a PReP machine have similar symptoms and any ideas on how to 
fix this?

Serial console output:

0 > boot net
LOAD: Waiting 60 seconds for Spanning Tree
BOOTP R = 1 BOOTP S = 1
