Hello,
trying to login as root?
Disabled for security reasons per default, anyway you should not use
telnet!
It's unsecure as hell and you should have ssh/scp on your machine, if not,
install it.
Of course you can tell me now:
Hey dude this box is only 2 m away from me,
but if it's somehow networked/internet connected that doesn't matter,
it's just a few msec away from anyone in the world. Even if your network
is secured highly,
I wouldn't use it, you never know if there is someone, doing something
nasty on your own network.
Just don't use telnet.
Good luck

Which device???
0x1603 doesn't even exist on my system.
Are you sure it didn't say 0x0316 instead.

Did you really?
Well if it really is looking for device major=16 I'm not surprised anyway.
Are the major numbers of hda correct (ls -l /dev/hda*)
Is lilo.conf correct?
Have you booted in rescue mode and supplied the "root=/dev/hdaXXX" option?
Or did you only supply "linux rescue" to the LILO prompt?

Weird. Im not aware of any requirement anywhere for a default SHMMAX?
Other than h/w or OS limitations.

Which you can do. Get heaps of info on the "recompile the kernel
bit", then do it once you are confident.

If you're running on segmented memory architecture (Intel + most of
the RISC chips), you slow down a bit if your SGA is across multiple
segments. Basically, SHMMAX defines the biggest segment of shared
memory that will be allocated. The size of the SGA is divided by this
and that defines the number of allocations needed to create the SGA.
Addressing across segments in this h/w architecture is expensive.
That's all.
>Will I be limiting the maximum size of SGA I can define?
In theory yes. In practice, no. The OS will allocate as many
"chunks" of SHMMAX size up to the number in SHMSEG. Which will be a
larger number than you need.

Hello:
fdisk \mbr
will restore the original dos boot. It BLOWS away the LILO hook.
To get LILO back, use a BACKUP floppy to boot linux, then type lilo.
Lilo will boot what it is told. If / is on the secondary master ( hdbX) it
should
have no problem finding it and booting.

NT writes a second MBR somewhere on the drive during installation, where
exactly I am not sure but I believe it is at the end of the drive.
You can do a little black magic to get your linux to boot from hdb. Try
switching drive assignments in the bios and then you will need to voodoo
windows by adding the following to the windows boot section in
/etc/lilo.conf
map-drive = 0x80
to = 0x81
map-drive = 0x81
to = 0x80
This will make windows see no changes to drive assignments. Hope this
helps...

Just delete all the partitions on the second drive, and continue with the
install.
There's no difficullty installing linux on a second HDD.
Preferably you would have it connected as hdb
(ie. slave on the first IDE controller)

I suppose the dos tool you're talking about is 3c5x9cfg.exe . then this
tool should show you the irq and base port curently being used. also
make sure that you have compiled 3c509 support with your kernel.

Subject: ethernet card config
Date: Fri, 16 Feb 2001 12:45:59 -0000
Hi there,
A networking/ethernet card config problem:
I have installed Mandrake on a machine which has what Windows called a
"3Com Etherlink 10/100 PCI for Complete Pc Management NIC (3C905C-TX)."
However, on startup Linux identifies it as "3Com 3c905C Tornado" and gives
the error "***INVALID CHECKSUM 002f***".
It identifies the card as being at 0xd800 with IRQ 10, which is what Windows
thought too.
The driver installed is 3c59x.c and the card is installed (term?) as eth0.
When I try to use dhcpc to configure networking, it times out. I take it
this is due to the ethernet card not working - is this correct?
If so, what do I need to do to get it working? Bear in mind that I don't
know anything about Linux - for example, which files control the
configuration of the card.
If this is too involved for a specific answer, where can I find a general
troubleshooting guide for this kind of thing?
Thanks.

Not if you create 2 partitions during the install of winME. If you let ME take
the whole drive then split it, I would run defrag before splitting the drive.

Richard,
that video card does not work with RH 7. I had the same problem.
So, I replaced it with an 8MB ATI rage pro, and it worked fine.
Sad to tell you, but you will need a new card to use RH7

For some reason 7.2 doesn't install the telnet-server, install it from the CD
and all should be fine.

What kind of terminal are you using? This seems more like an ncurses
problem. Just to be sure, try these
1)set the TERM environment variable to something respectible, like vt100
2)start up a ncurses program, such as joe or pine, or vim, or whatever.
3)Try the same from the console of the computer.
4)Still no luck, report back to us.

If you get no movement, then its probably the wrong device.
