Making Debian Linux Recognize More Than 4 GB of RAM – (BIG MEMORY)
If you have a server with 8GB of RAM and Debian could only detect 4GB by default.
Then you will need to install this package called “linux-image-2.6.18-5-686-bigmem”
This package provides the binary image and pre-built loadable modules for Linux kernel 2.6.18 on Pentium Pro/Celeron/Pentium II/Pentium III/Pentium 4 with 4-64G RAM machines.
How to Install
apt-get install linux-image-2.6.18-5-686-bigmem reboot
For DEBIAN Lenny
It uses package: linux-image-2.6-686-bigmem
This package depends on the latest binary image for Linux kernel 2.6 on Pentium Pro/Celeron/Pentium II/Pentium III/Pentium 4 with 4-64G RAM machines
How to Install
apt-get install linux-image-2.6-686-bigmem reboot
Piping a decade later, but one never knows…
Ubuntu is based on Debian; however, I can just find a ‘generic’ and a ‘low-latency’ version for the Linux kernel. There is no option for ‘bigmem’ or anything similarly sounding. I wonder (since you seem to be familiar with both Debian and Ubuntu) if there is any alternative way to specify a kernel designed for a system with tns of memory under Ubuntu as well…
