Recently I have ran an issue while installing and configuring 32 bit Suse Linux server on Vmware paltform. The Linux 32 bit systems couldn't recognise more than 4 Gb memory. The default kernel for Suse Linux 64 bit systems is bigsmp, which can read memory more than 4 GB. The default kernel for 32 bit Suse Linux systems is "smp", which can read up to 3 GB memory. Here I am discussing two tips to overcome this limit:
1. Install all physical RAM or assign total meory (like 16 GB)in Vmware settings before installing Suse 32 bit OS. It will take care of automatically and installs "bigsmp" kernel. You can see the total memory recognized by os with "free" commnad and it should be shown 16 GB.
2. If you want increase total memory after initial install of SuSe Linux 32 bit Os, you need to install "bigsmp" rpm from second or third OS dvd after installing physical RAM/allotting RAM in Vmware.
Have a nice day!
