Hi all,

Following my message of a couple of days ago I have tried to load 
FreeBSD by booting the machine from a floppy containing boot.flp as 
created by rawrite.exe.  I have tried FTP from my local mirror site 
(physics.usyd.edu.au), I have tried a parallel lap-link cable using 
lp0, I have tried FTP to my development machine which runs BSD and 
from which I have tried making my CDROM drive visible, as per my 
previous note to you.  I have also tried copying all the bin floppies 
to diskette and loading from these.  However, I get a page fault 
error, something like  the following which I obtained by asking for 
the debugging flag to be turned on in Options and by pressing alt-F2 
before running the system generation process.  I am able to delete 
the existing disk partitions OK.  I can create a new FreeBSD 
partition OK.  I can create three slices, /, swap, /usr.  The root 
directory, / , is about 30 MB, the swap partition is 16 MB (for an 8 
MB machine) while the /usr partition is is the remainder of the disk, 
about 68 MB.

The system generation process performs the newfs function and copies 
the root data to /stand, and eventually ends up with the following 
error screen:

DEBUG: strcmp(/dos, /usr) returns -17
DEBUG: Starting an emergency holographic shell over on the 4th screen
DEBUG: Generating /etc/fstab file

Fatal trap 12: page fault while in kernel mode

processor eflags    =interrupt enabled, resume, IOPL = 0
current process      = 59 (ifconfig)
interrupt mask       = net tty

At which point, the machin hangs.  Can you see what is going wrong?


Thanks

Kevin
