60df79fa4d Implement "safe mode" boot process 
Lots of ways this could be done. I have chosen to set it up so it just boots with a minimum driver set.

On SBC test  by setting BT_REC_TYPE to BT_REC_SBC02 and use the 1-bit jumper (crtact) jumper to enable.

Options for other platforms needs to be considered.

0bdecc9a4a Floppy Fix 
Floppy I/O was failing for slower CPUs when the timer interrupts were active.  Now fixed.

Credit to Jorge Jorge Rodrigues for finding this problem and pointing me in the right direction for the fix.

b856a1a529 Disk I/O to/from Banked Memory 
Supports double-buffered disk i/o to read/write to/from any memory bank specified.

NOTE:  Disk I/O will be temporarily slower than normal because all I/O is being forced thru double-buffering for testing.
