Re: [gentoo-user] No kernel boot after inserting more ram
Nothing to do about it... If he's using amd64 that option doesn't even exist. And even if he's on x86, if that option is not enabled, it will boot, but will just not use all the memory phisically available. On 1/18/08, Mike [EMAIL PROTECTED] wrote: Just a thought...

Well, if you haven't changed anything else other than the RAM module since the last time you booted the machine, then the problem would not be with your Grub configuration . . . If you have, then revert the change. Any help or ideas are welcome :) Boot a LiveCD and run memtest86. Sometimes even new memory modules are duff.
