>Description:
Intel Pentium 166mhz PCI motherboard with a TVX chipset with onboard 
serial/parallel ports, ide controller AMI bios V4.51PG 32meg memory.
When booting with a floppy (boot.flp), I get panic: page fault with
the following errors.

avail memory = 29073408 (28392K bytes)
DPT:  RAID Manager driver, Version 1.0.5

Faltal trap 12: page fault while in kernel mode
fault virtual address      = 0xf430d003
fault code                 = supervisor read, page not present
instruction pointer        = 0x8:0xf01ace03
stack pointer              = 0x10:0xefbfff70
frame pointer              = 0x10:0xefbfff80
code segment               = base 0x0, limit 0xfffff, type 0x1b
                           = DPL 0, pres 1, def32 1, gran 1
processor eflags           = resume, IOPL = 0
current process            = 0 ()
interrupt mask             = net tty bio cam
panic: page fault

I have tried removing all expansion boards except the display controller,
swapped the simms memory chips, changed almost every option in the BIOS
to try to affect the problem. I have entered the full-screen visual mode
and eliminated all the options that conflict and all the options period.
The error never changes, except if I remove all the options, the machine
re-boots.  
The computer works fine on Linux
