mark 30bb966970 Cleaned up the boot() function. Removed some of the garbage, 
rewritten parts and made sure it uses cngetc().
Don't try and syn the discs or unmount filesystems if boot() gets
called while still cold.
 1996-03-08 21:37:01 +00:00
mark 657b336f18 Restructured management of L1 page tables. Added support for 
detaching an L1 page table from a process that is swapped out.

mark a3aaf2a2c0 Removed old (and commented out) diagnostic code from 
undefinedinstruction() that verified the function was not
called in UND32 mode. We now always expect undefinedinstruction()
to be called in UND32 mode.
