Help!  I am having the same problems with `off-the-shelf' Minix 1.5
as I had with the demo disk.  This surprised me, as I have received
reports of Minix working `just fine' on similar hardware (I have
an Amstrad PPC640 portable with 2 3.5" 720K drives; I heard that
it works on a PPC512, which is the same, apart from the memory size).

I get the same results with each boot disk - the Minix 1.5 message
comes up on the top line, the menu is printed, but when I press =
or u, I get the following message starting on line 2 of the screen
(immediately below the Minix 1.5 message):

Nonmaskable interrupt
process number -9, pc = 0x0060:0x00000A70

Kernel panic: exception in kernel, mm or fs
Type any key to reboot

It is not a problem with the first keypress, since I can set the
three parameters listed on the menu OK.  (Also, there is no disk
activity between pressing = and the error message.)

I can probably get access to another machine to make appropriate changes
and recompile a version for my portable, so if anyone can tell me what
to do, I would be extremely grateful.  Please, *please* mail ideas
to me at walrmath@durras.anu.edu.au.  Thanks in advance.
