>Environment:
AT&T Globalyst 515 (NCR BIOS 2.08, 486DX4/100, 24MB RAM, removed SCSI drivers from kernel, no CD-ROM)
>Description:
      I get this panic (right after I exit the kernel configurator) when trying to boot my AT&T Globalyst 515 from the 4.9-RELEASE install floppies (some context included):

--snip--
Preloaded elf kernel "kernel" at 0xc0829000
Preloaded mfs_root "/mfsroot" at 0xc0829084
Fatal trap 12:  Page fault while in kernel mode
fault virtual address = 0x10014
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc02d29ec
stack pointer = 0x10:0xc084bf24
frame pointer = 0x10:0xc084bf2c
code segment = base 0x0, limit 0xfffff, type 0x1b, DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 (swapper)
interrupt mask = net tty bio cam
trap number = 12
panic: page fault
--end snip--

I have no FreeBSD machine to use as a serial console (I am trying to set up my first), and I do not think there is a way to get a backtrace if the install floppy panics.
>How-To-Repeat:
      Boot this machine with the install floppies.  Configure all SCSI drivers out of the kernel.  Watch it panic.
>Fix:
      No fix.
