cannot boot: initrd extends beyond end of memory error

**sanjay** · 07-27-2003, 04:26 AM

I couldn't boot from the Knoppix cd on my computer. It says:

initrd extends beyond end of memory (0x1eff3a32 > 0x1eff0000)
kernel panic: VFS: Unable to mount root fs on 01:01

After the knoppix boot screen it freezes with this error. I tried with many boot options and I couldn't get pass this error. I have AMD Duron based system with 512MB Ram. I have two 256MB memory sticks and I get the same error with two or 1 memory sticks, I did this 'cos I assumed boot script didn't recognize my memory properly. Could anyone help me out? I want to boot of the knoppix cd and install knoppix on my system. Did anyone encounter the same/similar error? Is there any other way of installing knoppix on my system???

Sanjay.

Have you tried booting with the cheat code mem=512M you may also want to try knoppix 2 to boot to a terminal and just run the install script from there.

Hello stephen,

I have tried both the options and infact many cheat codes, didn't get it work though. I had a similar problem with redhat linux. I booted with win98 cd with cd support and invoked the setup file of RH 8.0 , as I have two cdrom drives. I can't do the same here 'cos there is no setup file in this cd. Is there any similar process that I can follow to setup knoppix linux.

I don't think so I believe the cd has to be running to copy the system to the HD and make it bootable although I've been wrong before I would suggest subscribing to the developers list at debian-knoppix@linuxtag.org if any one can answer that question it would be them. Did the Redhat install work once you ran the setup from the win98 CD?

yeah,m Im using two sticks of 256 sdram and the retarded message comes up,
initrd extends beyond end of memory (0x1eff3a32 > 0x1eff0000)
kernel panic: VFS: Unable to mount root fs on 01:01

kernals shouldt panic!!! what do I do!!!

(Thanks for typin that, so I didnt have to)

--As was already mentioned, you have to start knoppix with the mem= cheat code. Sometimes it may not be exactly equal - for instance I had 196MB RAM and had to go all the way down to ' knoppix mem=190M ' for things to work.

Yeah, I am using two 256 MB memory sticks too. Fortunately, the mem= cheatcode worked for me. For some reason, It recognizing my memory as 496MB. So, I gave mem=496MB and it worked. I am able to install knoppix on my harddrive too.

Good luck.

Hi sanjay,

i think the difference of memory is caused by a shared-memory grafic adapter.
Can you confirme, that you are using 16Mb of your installed memory for the grafic adapter?
This memory can't be used by any OS.
