To specify the target memory access size

• Answer the "Target memory access size?" question.
When accessing target system memory locations, the access mode specifies the type
of microprocessor cycles that are used to read or write the value(s). For example,
when the access mode is byte and a target system location is modified to contain
the value 12345678H, byte instructions are used to write the byte values 12H, 34H,
56H, and 78H to target system memory.
Answer "bytes" if the emulator should make 8-bit accesses to target system
memory.
Answer "words" if the emulator should make 16-bit accesses to target system
memory.
To select the default physical to logical run
address conversion
• Answer "yes" or "no" to the "Enable max segment algorithm for physical run
addresses?" question.
The run and step commands allow you to enter addresses in either logical form, that
is "segment:offset" (0F000H:0FFFFH, for example) or physical form (0FFFFFH,
for example). When you enter a physical address, the emulator must convert it to a
logical (segment:offset) address. Your answer to this configuration question sets the
default algorithm for this conversion.
Answer "no" to cause the conversion to make the segment part of the logical
address as small as possible. For example, 0FFFFF becomes 0F000:0FFFF.
Answer "yes" to cause the conversion to make the segment part of the logical
address as large as possible. For example, 0FFFFF becomes 0FFFF:000F.
If neither of these default algorithms is suitable, you can enter addresses in logical
format.
