2.6 Memory Configuration with MemList
The memory size is set to 2MB per default with UsrMemEnd label in
DEFS/systype.d. If a EUROCOM-17 with a different memory size is
used, modify the memory list or choose one of the uncommented
UsrMemEnd samples in DEFS/systype.d. Set the 2MB UsrMemEnd to
comment and remove the comment for your configuration. Init.a
contains the following MemList:
MemList
* Select one of predefined UsrMemEnd labels in systype.d
(default is 2 MB)
MemType
SYSRAM,255,B_USER,4096,$00020000,UsrMemEnd,OnBoard,$c0020000
* MemType
SYSRAM,255,B_USER,4096,$00100000,UsrMemEnd,OnBoard,$c0100000
(Download version)
If you want to change the memory list, edit the file init.a in directory
SYSSRC. After modification of init.a, reassemble the file with the
following command:
$ make init
Now a new INIT module is built and stored as init in
CMDS/BOOTOBJS.
Examine the bootlist file in CMDS/BOOTOBJS, replace init.dd by
init, generate a new bootfile on the harddisk with os9gen and reboot the
system.
For further details of the INIT module and Colored Memory, refer to the
‘OS-9 Technical Manual’.
