Sarge + 1GB RAM how?
 
Hve just done an install of Sarge from the NETINST cd onto a P4 machine with 1GB of RAM and for some reason it seems to only be seing 960MB, any idea of how to sort this?

high mem support is required for ram >=1 GB
maybe u are u using a kernel which has that turned off
u will have to recomile ur kernel for that or see if ur distro provides a precompiled kernel with high mem support

regards

thought it might be that, anyone know a precompiled kernel image that has Highmem, SATA and RAID precompiled in thatI can just apt-get? or will I need to get one of the source packages and use make-kpkg ?

KaraK 01-06-2005 09:41 AM

The default kernel configuration from Debain does have high memory support turned off. You can turn it on by recompiling your kernel. Just use the existing kernel configuration as a starting point, run make menuconfig and select: Processor type and features--->High Memory Support. Change it from "Off" to "4GB". Then recompile your kernel. I wrote a step-by-step procedure for compiling a kernel that is a sticky at the top of this forum. There is also an excellent guide here: http://newbiedoc.sourceforge.net/system/kernel-pkg.html

cheers guys, looks like recompiling the kernel will be task no.1 tomorrow morning then!

Actually, I *think* that if you just upgrade your kernel using your favorite package manager (dselect, aptitude, synaptic, etc.) then you should be good to go. I have done this before and found that the kernel upgrades that come out tend to be compiled for 4gb environments, and that the kernel that is installed for an initial install is limited to the <1gb frame.
