I would use the full command below and place it just after the Server Name and Server ID commands (command is all one line):
load conlog file=sys:system\console.log save=sys:system\console.old maximum=2500 entire=yes
Basically, it loads CONLOG and specifies a file of SYS:SYSTEM\CONSOLE.LOG to write to. The SAVE bit ensures that when the server reboots, the old console log is saved as CONSOLE.OLD wich can be useful when investigating server crashes. The maximum specifies that the file does not exceed 2.5Mb in this case, entire ensures that everything on the server console gets written.
