The 384K of RAM that disappeared seems to be lurking at 0xE00000 (if I remem-
ber correctly) as normal RAM.  It can also be enabled with some granularity
(16K or perhaps 64K) in the 0x00A000-0x00FFFF range.  If you do not find it
at 0xE00000-0xE5FFFF, let me know and I will fish out the utility I wrote to
scan protected memory for such lumps of RAM.
