-  * word mode does not work - a 2 byte write to a location results in the lower address 
-  * byte being unchanged (4 byte writes are even stranger) and no indication of error.

-  * When port 0x78 bit 2 is set to 1 (flash device 1)
-  * 	0xfff80000-0xfffbffff seems to be free but has dos block headers
-  *	 0xfffc0000-0xfffdffff seems to be the DOS P: drive 
-  *	 0xfffe0000-0xffffffff  is the BIOS
-  * When port 0x78 bit 2 is set to 0 (flash device 0)
-  *	0xfff80000-0xffffffff is a mixture of used and unused DOS blocks and apparently
-  *	many copies of the BIOS
-  *
-  *  In the absence of information from Ziatech and to preserve the BIOS and DOS sections,
-  *  this driver only uses the first range for a total of 8 x 0x40000 = 2Mb
