d
The d key selects which device the current MMS page points to. Pressing the d
key causes the system to prompt for the new device. Enter a 0, 1, or 3 (0 = DOS
ROM, 1 = system RAM, 3 = BIOS ROM), and press enter. Invalid input is not
accepted. Once a new device has been entered, the main data display returns
showing the data read from the selected device at the current offset. For example,
if you are looking at the DOS ROM at offset 4000h, and you use the d command
to select the BIOS ROM, the data displayed is from offset 4000h of the BIOS ROM.
f
The f command allows a range of memory to be filled with a user-selectable byte.
Pressing the f command brings up prompts for the start and stop fill addresses, and
requests the fill byte. Fill operations are available only when RAM is the selected
device. This command does not know how to write to Flash devices in a DOS ROM
socket.
g
The g command allows you to “go” to any place in the memory map desired. It is
the random access equivalent to the plus and minus keys. It provides one additional
benefit in that the data byte which resides at the address specified by the user to
go to is highlighted for easy recognition.
i
The i key allows the DOS ROM interface to be toggled between the 8- and 16-bit
interfaces supported on the ÉlanSC310 microcontroller. This is useful if running
the utility on a hardware platform that has an 8-bit DOS ROM interface as opposed
to the 16-bit DOS ROM interface on the ÉlanSC310 Microcontroller Evaluation
Board.
l
The l command allows one screen’s worth of data to be appended to a log.
Successive screens can be captured to the same file in this manner. Pressing the l
command prompts the user as to whether the output file should be a binary image
of the data, or whether a DOS debug-like ASCII representation should be saved.
If the binary option is chosen, data is logged to a file named MMSVIEW.BIN. If
the ASCII option is selected, the output file is MMSVIEW.ASC.
