>Description:
Tried to install 1.4.2 on a Compaq Presario 5900Z with a 600MHz
AMD Athlon processor.  The motherboard has no ISA slots, although
the board appears to have pads to mount one.

Booting the floppies made from boot1.fs and
boot2.fs, or booting the boot-big.fs from CDROM yields a panic.
A transcript of last few lines of output before the error follows
(transcribed by hand).

The operating system has halted.
Please press any key to reboot.

Using boot-small.fs or boot-tiny.fs results in a successful boot.
I used boot-small.fs to install netbsd to the hard disk, however,
the installed kernel fails, dropping into the debugger with the
same panic message.

I tried images from 1.4.1 and 1.4 with the same results:  boot-small.fs
and boot-tiny.fs boot successfully, boot-big.fs and boot1.fs and
boot2.fs do not.  All images from releases 1.3.3 and 1.3.2 boot
successfully.


>How-To-Repeat:
Boot the kernel again.
