Wow! Not so fast. Do you have another operating system on there?

The first partition is the root partition and it is expressed
as:- 

/

Technically speaking that's all you need because grub and the
kernel images go there.

In practice however it is not a good idea to have one big partition
because over time you will download packages and want to keep them
safe if something goes wrong and you have to do a rebuild. So
it is usual to have one partition for user files and it is
expressed as:-

/home

The third is called opt or local and is where various packets
have been downloaded and compiled.

/local

Yes mount points as above but you will need to size each portion 
first to whatever you think appropriate, Whether you want a swap
partition or not depends on the amount of ram you have. It should
not be bigger than 256 Meg.

Nooo. The root partition should always be on the first hard disk
in an extended partition (/dev/hda5) or the second partition
on the master disk (/dev/hda2) assuming here you have another
operating system at (/dev/hda1).

I don't know much about Grub but Lilo can sit in the MBR or the (/)
of your first Linux partition.

Probably because you all ready had another boot loader in
the MBR.

If it's worked in the past then you can try it again but i would
not be happy having root (/) on the slave drive. If you can free
up some space on /dev/hda and make a little extended partition
on it your system will have much improved stability.

(/) Doesn't have to be very big but then you will need a /usr
partition.

These days ext3 is used and Ubuntu will be very happy.

 AH> I have eComStation 1.2R and WinXP, with IBM Boot Manager, on my master

This complicates things a little but not a lot. I have no idea
what eComStation 1.2R is or what file system you are running
XP on or how much spare space you have. Perhaps you need to
utilize the slave drive in another fashion. Why not repartition
the slave disk so it can compliment the master disk?

I have no idea how big your master disk is but you could
have a one or two gig XP compatible partition on the slave
drive and it should show up on your XP system as another disk
then of load as many data folders or saved downloads as you can
on the new slave drive partition. This will free up room on the
master disk for a small ext3 (/) partition. This is a stable
set up. Yum yum. :)

Then decide what size ext3 partitions and what mount points you want 
on the rest of the slave drive. Here is my partitions and
mount points.

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda5              1565392    260772   1225100  18% /
/dev/sda7              2016016    780300   1235716  39% /home
/dev/sda8              5423680   2072056   3076112  41% /local
/dev/sda1                48052      8080     39972  17% /mnt/dos
/dev/sda2             20788104  12312412   8475692  60% /mnt/windows
/dev/sda10            22888668   6141692  15584276  29% /opt
/dev/sda6              5052032   1742628   3052768  37% /usr


Just substitute /dev/sda for /dev/hda. See how small the amount
of used space is on /dev/sda5 is. Ok that can be the partition
on the master and the rest of the Linux can be on your slave as 
/dev/hdb.

Don't forget that on /dev/hdb you will now have a Win partition
and you should mount that as /mnt/windows2

What ever you do just make sure you don't have the boxes next
to your other operating systems checked when you go to format the
new partitions.
