[Simh] SET CPU 48M ?

[Peter Moreton]

Thanks everyone who replied, the solution was to AUTOGEN the machine:
@SYS$UPDATE:AUTOGEN SAVPARAMS REBOOT
@SYS$UPDATE:AUTOGEN GENPARAMS REBOOT FEEDBACk
FYI, my config.cfg is now:
 
set rq0 RA92set rq1 cdromset rq2 RA92set rq3 RA92att rq0 system.dskatt rq1 openvms71.imgatt rq2 data1.dskatt rq3 data2.dskset console telnet=42set cpu idle=VMSset cpu 48Mboot cpu
$SHO MEM now shows 48Mbytes available to VMS.
 
Thanks, peter
