Buffer Memory Mapping
Nonvolatile Memory Mapping
F/ EE = 1 (flash memory used)
F/ EE = 0 (EEPROM used)
Notes:
1. This attribute memory is an image from EEPROM. It is actually resident in upper half of the SRAM after power-on auto-
2. Refer to "Attribute Memory Mapping" for detailed locations.
3. The PENTIC+ decodes HA0-16 for memory access. The (common or attribute) MEMBase addresses are left for the host adapter
and the socket service to determine.
