MANDRAKE and 1Gig of RAM
 

I had 512 and the new Mandrake 9.0 which I liked. I upgraded to 1 Gig of RAM and Mandrake would no longer boot!! I installed Redhat but do not like it as much, but it had no problems with the RAM. Any ideas??

Sounds like you need to compile your kernel so that LINUX can handle your 1 gigabyte memory or more.

Just Linux has a good tutorial on how to compile your kernel.

There shouldn't be any special compiling to take place. The only thing is that you need to specify the amount of ram in your boot loader. I'm running a dual 1.12 Ghz with 2GB Ram -- Dual-booting between WinXP Pro/Mandrake 9.0.
Personally, I use LILO -- here's what you need to add to your append line in /etc/lilo.conf .

append="mem=1024M"

Inside the quotes, you may have other entries. Just add a space to the end & them add the mem=1024M to specify your Gig of ram.
