I can't boot the live cd (7.04) and found that my partition magic cd also will not boot. This is an ecs pt890t-a mobo with a celeron D cpu. I understand this a20 line is some ancient low memory thing.


edit:

!!! I found a reference that claims that iso's created using NERO use a boot method that can cause this problem:

I did use NERO to burn the live cd iso. But I thought burning an iso would create a cd identical regardless of which program was used to burn the cd. Is this correct????



Partition magic 8 cd complains about address line a20 already enabled (himem.sys or some such thing in the startup sequence).

Could this be what is causing my system to not be able to boot ubuntu live cd either?

The symptom is that the cd takes forever to read and seems to be timing out or something.

There's no bios option to turn this a20 off that I can find (I have seen this setting on older mobo's). Could the celeron not support this old memory layout stuff?

Any ideas on this one?

thanks

I have not had problems with CDs burned using Nero. Only issue is that (Ubuntu) CDs need to be burned at lowest speed.

It might solve the issue.

PS I assume that you burned as disk image.

You might be right here. It's working!

I used ubuntu to burn a cd, using the current 7.04 (don't know if this is an update or the same feisty I had dloaded some time ago) and this worked. I burned a different brand of media, and the only choice was to burn at max speed (using right click, write to disk..).


Then I tried again to boot my partition magic, and even though it still gives the same warning, it no longer hangs. So, I guess I'm stumped here. I had totally disconnected power, before when it failed, so I don't think that had anything to do with it. All I know is partition magic failed at least 5 times, and now, it's working just fine 2 times in a row.

And so is the ubuntu live cd with no cd hangups.

Well, now that it ain't broke any more, I'm not going to try to fix anything

thanks
