I think 5 Mb is small, but I tend to tinker a lot. Here's what's
worked for me in the past:
/dev/hda1 /boot small (20 Mb?)
/dev/hda2 / big (500 Mb?)
/dev/hda3 /usr big (1.5 Gb?)

Put your kernels in /boot, which means they're well below
the 504 Mb limit. More docs at:

I don't use dsl with earthlink; but I have to admit to having the easiest
time with earthlink on the road with dialup ppp. It works with wvdial
really well for me. I would call earthlink and ask specifically what modem
they are offering. At home for me, the Alcatel at home works very well.
All you do is plug one cable into the phone line and the other is a cat5
ethernet cable which goes to a nat/firewall box. No setup of pppoe or
anything.

Date: Fri, 16 Mar 2001 16:24:25 GMT
It looks like I will have to do more experimenting on a home machine
or set up a developement machine at work. Hopefully the Alt-SysRq-$KEY
will work, once I find out what it is. The majority of the dedicated
Linux machines are the newest or next to newest version of RedHat.
Like I said in my response in another thread, we handle about 300 or
so dedicated Linux servers, and at least at the present time there's
no one machine that dies more often than others, so there's no way I
can monitor what's happening before the server crashed, and there
haven't been any crashes like this since I started investigating my
ideas.
When you ask if I had tried to ssh in, no I haven't. But the reason I
know the machine is down is because it doesn't respond to ICMP
(pings.)
Maybe if the Alt-SysRq-$KEY key combination doesn't work, then I will
experiment with starting a getty process on /dev/ttyS0 on bootup.
Would a loopback connection to the serial port work to fool it into
thinking there was a console connction? Or would this cause other
problems?

Date: Fri, 16 Mar 2001 18:10:21 +0100
Hi,
i got a problem with my bwnfsd / pcnfsd on a SuSE Box 7.1, Kernel 2.4
The nkita is installed, the exports is OK (contains /var/spool/lpd & the
partitions to be exported). "showmount -e" shows them.
If i start the both processes by hand, everything seems to be OK. If a
NT-Client tries to mount the exported partitions, it crashes with a
blue-screen.
If the LINUX-Box is rebooted, the bwnfsd doesnt start & i got the
following error:
Starting PCNFS daemon done
Starting BWNFS daemon clntudp_create: RPC: Program not registered
startproc: exit status of /usr/sbin/rpc.bwnfsd: 255
failed
The portmapper runs correct.
Please does anyone has a suggestion where the error could be ?
Thanks in advance.

My box crashed ALL the time under doze.. then installed Linux.. It
crashed.. yes.. a few times.. per month.
Got hold of some Ram Stress Test Program and it told me that for 4
months I've been using faulty RAM!.. but linux still was
functional(partialy).. somehow.. If I pushed it it crashed..
What an awesome OS..

I have no idea about your machine, but my primary machine is a P133
and I have a 13GB disk in it. The BIOS recognizes it correctly, but
it hangs at boot. I can either make BIOS ignore the disk (this is hdb)
or recognize only as 8GB. In these cases it boots. However, when I
partitioned the disk under Linux, in the fdisk I went to the expert
mode and reconfigured the geometry to reflect the true 13GB size.
Linux doesn't use the BIOS for the disk stuff. It handles it entirely
on her own. This is why I could use it even it was not recognized by
the BIOS or the BIOS had the wrong idea about it.

You don't need the first 5MB as root. What it recommends (I think)
is that you have a 5MB partition at the beginning which would be
/boot and this would be where your kernel image is. The kernel has
to be under 1023 cylinders entirely (newer Lilos don't need this anymore),
and this is the reason that /boot partition is mentioned. I never had it,
I do these things on my own, but for beginners, this is clearly a
good way to go.

The master boot record (mbr) is not only "in the first 1024 cylinders".
It is the very first sector on your disk. It is in your first one
cylinder. When the system boots, it reads the contents of the first
sector on the disk (head0, cylinder0, sector1) and executes it.
In that sector you have lilo which in turn will load the kernel.
By definition, at this time, you still rely on the BIOS' idea of the
disk geometry, and it has this 1024 cylinder limitation. This is
why the compressed kernel image (vmlinuz) should be under it.
Once the kernel is up and running it will probe your machine for
everything, including the hard disks, and will recognize them correctly.
As I know, never Lilos don't have this 1024 cylinder limitation,
but I have no experience with it.

Shouldn't be needed. In my experience most computers can't tell the
difference between an unplugged terminal and one thats switched off.
Plugging a terminal in and switching it on should get the system's
attention if its going to respond at all.
Note: I'm talking about a genuine terminal, such as a Wyse-60. Things
might not be quite so easy if you're running a terminal emulator on a
PC of some sort.

...<snip>...
Different SCSI controllers have different device drivers. You get a list
when you do 'make config' (or xconfig or menuconfig) on the linux kernel.
There are drivers for Adaptec, Buslogic, etc. I use a Tekram controller
and I have to go to Tekram's website to download the driver source and
patch it into my kernel source tree. One reason I'm not running kernel
2.4xx right now is that Tekram hasn't come out with a driver for it yet.
Also, different devices on the SCSI bus will have different drivers.
The SANE driver I use for my scanner on the SCSI bus is different from
the disk controller driver. I'm not qualified to go to a deeper level
than that on the linux kernel. Looking in the help files and other
documentation that are in /usr/src/linux and that are accessible
during a make config might help you identify exactly which packages
are involved. If anything is a module you can play around with insmod
and rmmod (when I want to use the scanner I have a whole hierarchy of
insmods I have to do in the correct order). Ultimately, if there's a
bug, I suppose you could report it on some mailing list for kernel
hackers, maybe even find the author of the driver from comments in
the source code.

Please post your script. It should work. I also redirect many

Maybe your problem is different. Are you sure that what you see

I should probably remind folks that if your boot partition is accessed
via a SCSI drive, that SCSI driver can't be a module because the
kernel wouldn't be able to load the module to read the drive. At the
very least, the image for a kernel that uses modules has to have built
into it the software to read the partition and understand the
filesystem of where the modules are stored.
