HelloI am not that an experienced linux user, yet I had installed debian in several machines. This is my first experience with DSL but I get the following problem
I have a Pentium 133 with 16M ram and no bootable cdrom.
I boot from floppy and I have tried normal boot (just enter), lowram, and the super low ram as described in the wiki.
My main problem is the after
Scanning for harddisk partitions and creating /etc/fstab/ ... done
using swap partition /dev/hdc2
I get
mount can't find /ramdisk in /etc/fstab/ or /etc/mtab/
afterwards many others problems occur leading to a simple shell with no X.
Any help would be much appreciated :-)
Here's the full output:
======
lowram
======

Processor 0 is Pentium 75-200 132Mhz

about the same. The difference is that I get some more skipping this and that. In the ende I get again

I forgot to mention that I used both the dsl-3.0.1.iso and the dsl-3.0.1-syslinux.iso witha) no boot options
b) lowram
c) super low ram (as mentioned in the wiki)
but the result was always the same
I hope this helps a bit

What does it say before "Starting init process."from "Accessing DSL image at..."
If you can, you could also try pasting the output of 'dmesg' when you are in the shell.

HiIt begins with:
Accessing DSL image at /dev/scd0/
Total memory found: 13264 kB ( <==== I have 16 MB)
Creating directories and symlinks on ramdisk ... Done
Starting init process
INIT: version 2.87-knoppix booting

etc (from now on, as described in my previous post)
Moreover, I noticed that before saying:
Uncompressing Linux Ok, booting the kernel
it says:
You passed an undefined mode number
Press <return> to see video modes available, <space> to continue or wait 30 secs.
I skipped this one as I sometimes went away from the PC fo more than 30 sec and it just continued. I selected a different mode but nothing different happened.

Try booting with mem=16Mhowever, if you used shared memory i.e. with your video, etc. subtract amount from 16 and use that instead.
Don't worry about the undefined mode # for now, but that's usually fixed by specifying the geometry to fit your monitor (by vga= )

boot: dsl mem=16M
I tried this and I still get the same :-(

Even if I leave it as is (press space) or choose any of the modes, the result is the same...
Hope you didn't run out of ideas :-)
Posted by ^thehatsrule^ on Nov. 02 2006,18:12
Are you sure you aren't using shared memory anywhere?Maybe try booting with mem=12M - try combinations with the superlowram/failsafe/etc. Maybe you should also try booting directly to console first (dsl 2).
Hm, did you try like vga=787 etc? Doesn't matter anyways atm. (maybe you need to use fb modes)
Also, did you check if your DSL media was corrupt, or if it worked on another machine?
Posted by drio on Nov. 02 2006,18:45
I am quite sure there is no shared ram. I mean that there is no audio or network or modem devices on the mainboard. I also have mounted a graphics card, which previoulsy worked with debian and X on this machine.Is there any way to identify the usage of shared memory?
Also even if I try vga=787 and others I still get the indefined mode number...
I had previously checked the md5sum of both floppy and cd. I now tried the cd on my AMD sempron and it works fine. Now that I have seen DLS running, I must admit it's quite cool! Look what 50M of bytes can do :-)
I just noticed that for hdc "QUANTUM FIREBALL1280A, ATA DISK drive" (my hard drive) dmesg says:
hdc: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hdc: task_no_data_intr: error=0x04 { DriveStatusError }
Could there something be wrong with my hd drive? But then how does it creates /etc/fstab?
Posted by ^thehatsrule^ on Nov. 02 2006,19:04
"mounted" cards doesn't mean that it doesn't use shared memory afaik...You can output `lspci -v` maybe.
You'll probably have to manually compute a code for your monitor/video if the general vga or fb codes don't work. What type of monitor are you using?
Hm, `cat /etc/fstab`? Maybe try disabling your hdd in your bios before trying to boot again.
Wonder if all these problems are because of one thing...

Hi.
There's probably nothing wrong with your HDD, I've seen that message before on "functional" systems. Linux also detects 13MB for my config, 3MB isn't much for the kernel.
Furthermore, I think I have posted your solution here: < X problems - runlevel 2 >
Regards,
bkil

bkil:I tried to follow your instructions althought I don't think I understand what
/grub\ dsl 2
is this one.
Also I don't understand the
su dsl
from what I have seen only sudo su is needed.
Hoever all the other are working up to a point. In order to rm the directories I have to be su (I get permission denied). If I start X as su I get several stuff. But this could be due to the fact that su can't have X in dsl?
If I start X as user dsl everything is working fine :-) :-)
Thanks both bkil and ^thehatsrule^ for your time

Dear drio,Glad to hear you've got DSL working.
About my instructions: well, I have to confess that I made them up from memory, :blush: you see I don't boot LiveCD's too often, I only needed those commands as a quick hack to make harddrive install work on a PC... Let me try to clarify that post a bit (again from memory)
The first line was supposed to mean that I think it's sufficient for you to simply enter "dsl 2" at the grub boot prompt (you could append other parameters as you will), and as a consequence, the CD will log you into a rather clean root session (no "sudo su" needed for the empty /tmp, /opt recreation).
"su dsl" (or "su - dsl" if you'd like to have a login shell) is needed to change user from root to dsl, to enable you to run startx (it's not needed for installation of course).
After a harddrive install, you probably make both your /opt and /tmp non-volatile, so you don't need these "tricks" later on.
And the superuser can also start X sessions (at least on a hard install), his(her) config files in /root work the same way as any other user's in /home/*. Not that root would need X or anything...
Anyway, if startx throws errors, you need to either set your home directory, or make sure you use a valid configuration by copying, creating or editing your (hidden) config files and scripts. (Though all worked as expected automagically after a full HD-install over here)Yours,
bkil
