Re: Technical question boot problem

[Ken Yap]

I bet it definitely works (boot on XT drive) if one disables the onboard
IDE first.
The problem I see is using IDE and MFM/RLL drives at the same time,
which might prove difficult.

To boot XT drives on an AT+, one usually has to disable the IDE drives
so that the BIOS doesn't go looking there. XT controllers usually have
an extension BIOS to hook into the main BIOS boot entry point.

I really don't see where this is a problem. User level processing does not
need
hardware memory protection; it could be implemented as a strictly software
solution. For example, a table defined within the OS giving the user and the
level. Then, all memory access could interrogate this table and give pseudo
memory level security.

   In addition, the user programs could be protected from the kernel and
vice
   versa...

 Note, without memory protection we really have no lower priviledged users,
all users
 are the equivelent of root.  Users exist merely to provide some logical
division.

 
  And that would be a big bonus, especially for embeded systems
