That's because it has nothing to do with LILO (or any other bootloader
for that matter)
It's a limit originating from your BIOS

Wether you can boot from beyond cyl. 1024 is forced upon you by your
BIOS. If it understands the extended int13 calls it can, if not, now way
you can ever boot from beyond that limit. The newer LILO's can use these
calls, but if your BIOS doesn't understand them, well, too bad (use
loadlin, or create a /boot below cyl 1024)

Unless you use another OS on these discs I don't think there's a big
problem, but using windows/DOS with this table will be a good way to
destroy data (make hda4 type 0x85, it isn't a correct ID now (0x05),
although it won't hurt with linux either)
Change hdb1's partition ID too, to 0x0e (I'm not sure if it's needed (is
the limit 1023 or 1024?), but it's a safe solution anyway.
If you really don't like it, try parted, from GNU, maybe you can resize
the partitions, so fdisk won't complain anymore. (PartitionMagic can NOT
help you here)
But if you resize, be carefull not to overwrite a neighbouring partition

This line will make sure LILO is NOT in the MBR.
That way the lba32 line will be pretty ineffective :-)
Should be:

I don't know PICOBOOT, but I guess it's a linux-on-floopy distro
supply the C/H/S parameters of the HDD when booting, to force the use of
teh corrcet parameters.
I cannot be sure if this will solve anything, but that's your own fault,
telling us that some command "gives errors" isn't much to work with.

Hi Eric!
thx for your reply. You've made it much easier for me to sleep at night now...;)
But still one problem remains, which I think this is not the right newsgroup for:
I'm trying to install AtheOS (a new alternative OS - see http://www.atheos.cx) on hda3
but it doesn't recognize hda at all only hdb :(
Just thought that the strange partition table on hda might be a reason for that.
But maybe not. I will have to join the mailing list for AtheOS anyway...

I would *like* to, but I'm not sure if I can.
When you use loadlin (glad it worked out for you) you were in windows
previously. Windows set's up the modem for you, using it's settings. Now
when you boot linux, these settings aren't restored to the default
values. Try hard/soft resetting your modem. I don't know much about
this, I've a winmodem :-( (That means no modem, just heavy CPU load)

I've seen more messages like this, appearantly the LILO suplied with
RH7.0 is broken
(Yes it works on some systems, I know, but it may be a specific setup or
something)
Try using a bootfloppy from RH6.x, update LILO and rerun `/sbin/lilo`

I'd stay away from the RAID setup. It's not a 'true' RAID. Do you really
need it? You only listed one hard drive.
Nice setup though!

Any Linux distro will work. But you have to remove all
unnecessary things (daemons, Desktops etc.). Of course,
Netscape will use all the memory you have.

A low-traffic web-server needs less computing power than Netscape.

Here's the situation. I have dozens of Linux boxes in a lab. I have a
software package in RPM format that I want to install on all of the remote
boxes. I'm on an NT workstation (I can go to a Linux box if it is easier).
What would be the easiest way to copy this RPM around and install it on the
boxes? Do I use NFS, Samba, or FTP? Then how would I run the install the RPM
(ssh, telnet, something else...)? Can anybody think of a simpler way to do
this?
Thanks,

That was just an example (from my system) only intended to show how to

Okay I mentioned windows as a potential danger, but the same goes for
any other OS.
There's absolutely no guarantee that another OS will interpret the
partition table the same as linux does. partition table are a potential
danger if you mix OS'es. Always keep a very simple partition table. You
used features that are allowed in a partition table, partition
boundaries that don't start/end on cylinder boundaries, (I don't know
why you did this, but that doens't really matter), but other OS's may
not be aware of these options (DOS eg. cannot deal with this!) I don't
know atheos, but I wouldn't guess it will handle the table correct. Your
100% safe as long as linux is the only OS that uses this table,
otherwise it is guessing.
Sorry to ruin your nights again :-|

This is in your lilo.conf??
I fail to see why the lba32 line is there,
if hda3 lies below cyl 1024, it's not needed, if hda3 is beyond cyl
1024, it won't work.
Or did you copy your lilo.conf file (which does not contain the lba32
line) and added the line as an example. Then I can understand this
again.
