I have the following system configuration and I have been unable to 
successfully boot from the TinyBsd floppy. I retreived this floppy from 
agate.berkeley.edu around 12/92 and have verified that it works fine on
various other systems.

	 386/486/387:  Utron 386/40MHz  AMI Bios
	 ISA/EISA/SCSI: ISA 
	 RAM size: 4 Meg
	 drive(s) type and size: Quantum LPS-120 256K cache
	 tape(s) type and size: Colorado 250 MB
	 ethernet type: none
	 graphics type: EGA / ATI EgaWonder (very old - 5yrs or more)
	 serial type: 2 serial ports on IDE disk controller
	 parallel type: 1 parallel port on IDE disk controller
	 other: USRobotics 14400/PC FAX Modem


After the system reads the drive for about 30 seconds I get the following error message:

trap type 19 code = 0 eip = fe00076c cs=8 eflags = 3002 cr2 0 cpl ffffffff
panic: trap
hit reset please

I have tried changing the AMI BIOS configuration so that shadow ram 
and caching are disabled. I have also removed the modem from the system. So
far everything I've tried has been to no avail.  

Any help would be greatly appreciated. In particular, does anyone out there
have experience with the same motherboard? Is there any useful information that
can be gleaned from the error message. (I know what the registers and flags 
mean, more or less, I just don't know what to do about it). Where do I go from
here?
