RE: AlphaServer 800 Installation



Thank you ever so much for helping!  I have been struggling now for a week. Here is the extent I can record of the paging error.  There are two screen of data that scrolls by before I can write it down.  If we need that too, you will have to show me how to stop the screen from scrolling (I tried ctrl-s and even the [pause] key but neither stops the screen.

Helge – I saw on some messages that some people with Alpha boxes had this paging problem when they were using kernel 2.2 and 2.4.  I noted that one person reported the problem did not occur when they used kernel 2.6.  I have downloaded sarge (which I believe uses 2.6) and I plan to try that later today.  Thanks again for your help.

Are you using the woody boot floppies installer or the new debian



I have been using Woody CD images.

Can you try to copy down this paging error? This seems the real cause

of the problem.


Will do…

The documentation is just giving examples from "normal" operation.

Depending on the name of the kernel to boot, this line my be

different. But Yes you are right, it looks a little strange. Can you

try (at the aboot prompt):


b /boot/linux root=/dev/ram initrd=boot/root.bin

I used this just now to recreate the paging error I am documenting.

During the initial install a ramdrive is used, so this setting is

probably correct. OK

There should be a file /boot/root.bin which contains an INITial

RamDrive, i.e. a small container holding lots of drivers and other

modules. Thanks.

This should not be needed. I don't know if it is even considered at

all. I will ignore.

I think this was used in the past when you actually applied floppy

disks. I don't think it is in use today still.  I will ignore.

Well, the problem is a)that people usually get M$ preinstalled and

b)you've (unfortunately) run into a strange install error and c)alpha

are different considering booting (though when running they are pretty

similar to i386 linux), so there's an extra hurdle here for the

newcomer.  Agreed.


Please try to post the exact error message about this paging and then

we can better help you.
